A prática de simulação computacional é tradicionalmente utilizada para a otimização de circuitos industriais de cominuição. Neste tipo de trabalho, a metodologia geralmente inclui as etapas de amostragem, modelamento e a simulação de diversas alternativas para a otimização do circuito. Esta prática se destaca por não envolver a necessidade de plantas piloto ou testes industriais. Com isso, configurase como uma opção de baixo custo e ágil, permitindo a análise detalhada de diversas opções de fluxograma e condições operacionais, exigindo, para tanto, mão de obra qualificada nesta metodologia e um computador com o software adequado. Este trabalho demonstra a aplicação da prática de simulação computacional no circuito de moagem do Sossego, da Vale, localizada na região sudeste do Estado do Pará. Tendo em vista o caráter pioneiro do circuito de moagem existente no Sossego, que inclui o primeiro moinho semi-autógeno de grande porte do Brasil, foi realizada também uma extensa revisão bibliográfica sobre a operação e a otimização desse tipo de circuito, visando contribuir para a consolidação deste conhecimento no país. / The practice of computer simulation is traditionally used for the optimization of industrial grinding circuits. The methodology usually includes surveying campaigns at the selected circuit, followed by data analysis, mass balancing and modeling. The latter consists in fitting mathematical models of each process equipment. Once the simulator is calibrated, a number of simulations may be carried out in order to explore different operating scenarios, related to optimization on the basis of selected performance indices. The simulation is thus an alternative for extensive and expensive pilot plant campaigns, as well as industrial tests. Accordingly, simulation is a low cost and low time demanding alternative, allowing the detailed assessment of several flowsheet options and/or operation conditions, even though it demands a qualified person and a professional software. This work presents an application of computer simulation program carried out at the Vale´s Sossego industrial grinding plant, located at the south-east part of Para state. As the Sossego circuit includes the first large diameter semiautogenous mill installed in Brazil, the literature review was largely focused on operating and optimization aspects of such a process, thus seeking to consolidate this kind of knowledge in Brazil.

The mining industry has long played a significant role in regional development in remote regions throughout the world. For the last two decades, the industry has faced high expectations regarding sustainable development and corporate social responsibility, particularly in remote and environmentally sensitive areas. Mining community models and mineworkers’ accommodation strategies in remote locations have varied greatly, yet there has been little documented reflection on the various models’ performance or on their implications for the quality of life (QOL) of mineworkers and their families and for the pre-existing local communities. This multidisciplinary case study research used a subjective quality of life approach to investigate the levels of satisfaction with QOL and specific aspects of QOL domains in three communities: the company town, the gate development community and the integrated community. The triangulation of data from qualitative and quantitative methods was used to examine the major QOL factors that should be taken into account by mining companies, local governments and policy makers when planning for mine development in remote areas. Findings suggest that differences exist between the mineworkers’ levels of satisfaction with specific QOL aspects and how QOL predictors are defined in distinct mining community models. Even though the case studies represent clearly different models of mining communities, in general, mineworkers in the three communities seem to be only moderately satisfied with their quality of life. It is also suggested that employees living in two almost opposite models—the company town and the gate development community—seem to have similar levels of satisfaction with overall quality of life, suggesting that the investment in infrastructure and services limited to the boundaries of the company town is not reflected in a generally improved perception of overall quality of life in this community. Findings also support the argument for an environmental and social impact assessment process for new mines in remote areas. This process should include a full and integrated consideration of the economic, environmental and social impacts of the workforce migration to remote areas and the consequent intensification of the already rapid urbanization of environmentally sensitive areas such as the Brazilian Amazon.

O Programa de Educação Ambiental (PEA) da empresa Vale constitui-se no fenômeno pesquisado, instituindo-se como objetivo específico a análise do Programa de Educação Ambiental desenvolvido pela Vale na Escola Municipal de Ensino Fundamental Adelaide Molinari, situada na Vila Planalto, município de Canaã dos Carajás-PA. A pesquisa possui abordagem qualitativa como aporte metodológico, com observações in loco na Escola Adelaide Molinari, estabelecendo-se as falas dos sujeitos entrevistados como as bases de análise do PEA da Vale. O resultado da pesquisa demonstra que o Programa de Educação Ambiental desenvolvido na Escola Adelaide Molinari trata a questão ambiental nos aspectos meramente físicos e naturalísticos em detrimento da questão socioambiental. Esse fato favorece implicitamente a Empresa Vale que, por meio de sua orientação de conteúdo trabalhado dentro da Escola, não enseja questionamentos da comunidade quanto às ações degradantes promovidas pela empresa. A pesquisa apontou a ausência da efetivação da Política Municipal de Educação Ambiental pelo poder público local. Constatou-se também que essa ausência favorece a ação da Vale, que insere suas atividades educativas no Sistema Municipal de Ensino sob a alegação da parceria existente entre a empresa e o poder público local, o que faz com que o referido Programa de Educação Ambiental deixe sua condição de atividade a ser desenvolvida na perspectiva da educação não formal e se transforme numa diretriz de educação ambiental formal no Município. / This Dissertation, entitled Environmental Education in Canaan of Carajás: the Program of Environmental Education developed for the Vale Company at the Adelaide Molinari School. It aims in the context of the Line of Research Educational Public Politics of the Program of Posgraduation degree in Education (PPGED) of the Federal University of Pará. The Program of Environmental Education (PEA) of the Vale company is constituted in the researched phenomenon, being instituted as specific objective the analysis Program of Environmental Education developed for the Vale Company at the Adelaide Molinari Municipal of Fundamental Teaching School, located in the Vila Planalto, municipal district of Canaan of the Carajás-PA. The research has qualitative approach as methodological line, with observations in loco at the Adelaide Molinari School, having the interviewees' speeches as the bases of analysis of PEA from the Vale Company. The result of the research demonstrates that the Program of Environmental Education developed at the Adelaide Molinari School treats the environmental subject merely in the physical and naturalism aspects in detriment of the socio environmental subject . That fact favors indirectly the Vale Company, through your content orientation worked inside of the school, it not provokes the community's questions about to the degrading actions promoted by the company. The research pointed the lack of the starting of the Municipal Politics of Environmental Education for the local public power. It was also verified that that absence favors the action of the Vale Company, that it inserts its educational activities in the Municipal System of Teaching under the allegation of the existent partnership between the company and the power local public, which provokes that the Program of Environmental Education leaves its activity condition to be developed in the perspective of the education non formal and become a guideline of formal environmental education in the Municipal district.

As mudanças vividas nos territórios ocorrem instantaneamente, pois o governo municipal e a Vale se articulam para preparar o município para o startup do projeto Ferro Carajás S11D, buscando neste momento investir em infraestrutura voltada às construções e reformas dos equipamentos públicos, trazendo, por um lado, muitos impactos positivos, devido à aceleração dos investimentos e atividades na região, e, por outro, impactam negativamente, criando um caos devido ao incremento no volume migratório, pois os Projetos em atividade na região continuam funcionando, há mais de 30 anos, de forma ininterrupta, fator que fortalece a migração de pessoas de todos os estados da federação. A pesquisa no território paraense analisa até que ponto a gestão territorial se beneficia das atividades exploratórias de produção mineral, advindas dos Grandes Projetos energéticos e busca analisar as ações diretas da empresa Vale na melhoria da qualidade de vida da população local, analisando também o comprometimento e responsabilidade da empresa relacionadas à sua atividade e tomada de decisões buscando minimizar os impactos negativos causados à sociedade e ao meio ambiente. A pesquisa busca também analisar as relações estabelecidas entre o Poder Público e a empresa, bem como analisar as territorialidades exercidas para o controle de área, através dos dados divulgados pela empresa Vale e pelo governo Municipal relacionados aos investimentos em projetos de Responsabilidade Social, visando mensurar a qualidade na aplicação dos recursos voltados ao desenvolvimento sustentável local. / In this article, we will try to introduce a research related to Social Responsibility Actions undertaken for the mining company Vale in the municipalities of Parauapebas and Canaã dos Carajás, because both as cities has the largest Mining Projects in Brazil, and Canaã soon will welcome the Major Mining Company the planet Called Ferro Carajás S11D project. The experienced changes in territories occur instantly, as the Municipal Government and Vale are organized to prepare a city to begin the Carajás S11D project, looking this time to invest in targeted infrastructures construction and refurbishment of public facilities, bringing many impacts positive results due to the acceleration of investments and activities in the region negative impact to create chaos, because the increase in volume migration, because the projects in the region are still working more for longer than 30 years of form interruptible that strengthens the migration people all states.

Seu principal objetivo é identificar como as políticas estão estruturadas, quais são as estratégias de comunicação utilizadas, e quais são os impactos socioambientais causados nas comunidades atingidas. Utilizou-se a teoria social crítica para análise dos dados e informações obtidos neste estudo, o qual envolveu empresas mineradoras das três mesorregiões que compõem o estado do Pará. Na pesquisa empírica foram entrevistados representantes das comunidades, do governo, das empresas e das organizações privadas, valendo-se das seguintes ferramentas metodológicas: observação in loco/entrevistas, diário de campo, redação e transcrição das entrevistas, análise e sistematização das entrevistas, e redação da dissertação. Os principais resultados da pesquisa indicam que a postura “socialmente responsável” afirmada pelas empresas passa pela necessidade de criar consensos nas comunidades, minorar a pobreza local e estabelecer a legitimação da empresa sobre o território; que as metodologias estratégicas de comunicação tem influenciado no modo de pensar e de agir dos atingidos pela mineração e dos profissionais envolvidos, devido abstraírem as condições de vida materializadas na cotidianidade e criarem conceitos ilusórios para explicar a realidade daqueles que sofrem os impactos socioambientais dos projetos minero-metalúrgicos; e que apesar do crescimento econômico gerado pela mineração e do investimento em políticas empresariais para mitigação dos impactos socioambientais nos municípios pesquisados, as comunidades atingidas por projetos minero-metalúrgicos continuam sofrendo com violações de direitos e acirramento das desigualdades no âmbito social, político, econômico, cultural, territorial e laboral. / This research aims to analyze the “social” corporate policies implemented in communities affected by mining-metallurgical projects. Its main objective is to identify how policies are structured, what communication strategies are used, and what are the socio-environmental impacts caused in affected communities. Critical social theory was used to analyze the data and information obtained, which involved mining companies from the three mesoregions that make up the state of Pará. In the empirical research, representatives of communities, government, corporate companies and private organizations were interviewed using the following methodological tools: on-site observation/interviews, field diary, writing and transcription of interviews, analysis and systematization of interviews, and essay writing. The main results of the research indicate that the "socially responsible" stance affirmed by the corporate companies is based on the need to create consensuses in the communities, to reduce local poverty and to establish the legitimacy of the company over the territory; and also that strategic communication methodologies have influenced the way of thinking and acting of those affected by the mining and the professionals involved, due to the existence of life conditions materialized in everyday life and create illusory concepts to explain the reality of those who suffer the socio-environmental impacts of mining-metallurgical projects. In addittion, it is concluded that despite the economic growth generated by mining and the investment in “social” corporate policies to mitigate socio-environmental impacts in the cities surveyed the communities affected by mining-metallurgical projects continue to suffer from violations of rights and intensification of social, political, economic, cultural, territorial and labor inequalities.
