Tipo de cimentação em materiais duros do perfil de alteração da mina de fosfato da Anglo American, Catalão-GO

One of the main challenges in the mining sector at present, related to the optimization of mineral assets, consists in to find the best proportion of each geological material to be mined and homogenized to ensure high productivity and stability in ore processing plants. The stability of a mineral processing plant is factor for achieving operational excellence, as a stable performance of the plants ensures economy and adherence to financial planning businesses. Is already well Know that the feed rate of the processing plants is dependent on the hardness and quality of the ore. Therefore, the ore behavior predictability is the solution to ensure the stability of mineral processing plants. This work was developed in Anglo American Phosphate Brazil Ltda., at the Fazenda Chapadão Phosphate Mine, located in the southeastern portion of the state of Goiás, in the municipalities of Catalão and Ouvidor. The phosphate ore is the result of supergene apatite concentration in the weathering profile of the alkaline ultramafic phlogopitized rocks, intruded by foscoritic and carbonatitic rocks series. The weathering profile has about 100 meters thick and is divided into three basic types, from top to bottom, coinciding with decreasing intensity of weathering: oxidized ore, micaceous ore and weathered rock. In each portion of this weathering profile, mainly near the contacts between these three divisions, are hard materials, cemented by minerals such as apatite, quartz, goethite, monazite and barite. The different features presented by these materials makes to be vital the correct identification, quantification and location of different hard materials in the mine area, to maximize its use. The main objective of this study was to define the type of cementation of hard materials which predominates in each portion of the weathering profile in the mine, as well as their relationship with the protolith. The work involved geological mapping, channel sampling...

A escola do urbano no campo do município de Catalão/GO : ensino de geografia nas especificidades do lugar

This study makes an approach to the Morro Agudo Community (Cisterna) located in Catalão city(GO) rural area where stands the Maria Bárbara Sucena Municipal School. This school center is a result of getting together several small and isolated schools, which worked, scattered in many rural communities in the region. After this centralization in a single school, many students had to move along inconvenient distance to get their classes. Morro Agudo Community (Cisterna) was outstanding at garlic cultivation throughout the 1990`s when eventually this activity came to a decline. The region is constituted by properties of small tract of land. The landowners come from a Portuguese background and there are, in addit ion, migrant workers from the northeast region of Brazil. These northeasterners work for these local landowners, and that brings an additional meaning to the social relations in the region and to the rural schooling. The social and cultural diversity of the region has a feedback at the school arising tensions in many ways. In the teaching and learning process the school deals with this diversity, combined with rules and goals that, in the end, delivers a geography teaching not able to value the local knowledge accumulated in the region by its own inhabitants. New methodological approaches to rural school communities emerged out of the analysis of these unmet expectations. Furthermore, this study takes into consideration some “residues”, that means not all events are fit into programs; there are unintended consequences in an open process. All these are object of deep review in this doctoral dissertation. In this community, an analysis of the public policies implemented by Federal and municipal governments to rural schools communities in Brazil was conducted. The way in which public policies toward rural communities are implemented at the schools was reviewed; the goals they pursue and the role played by textbooks are also object of analysis. This study questions the relevance of this tools, mainly if they meet the real needs of the local people. The social representations of teachers and students are considered carefully based on their everyday lives and experiences.

Intrusão Alcalina de Morro Preto (go): Geologia, Petrografia e Geoquímica

A intrusão alcalina de Morro Preto, localizada ao norte da cidade de Piranhas (GO), corresponde a um corpo irregular a subcircular com aproximados 3,34 km2 alojado em gnaisses atribuídos ao Arco Magmático de Goiás. É constituída principalmente por carbonatitos e lamprófiros com graus variados de laterização e silicificação, além de silexitos e, em menor expressão, por sienito ferruginizado e basalto alcalino. Quimicamente mostram baixas concentrações em Cs, K, Na, Rb e altas concentrações em elementos como TR, Nb, Ba, Th e U. Isto aparenta resultar de processos de laterização/silicificação e da formação de fases minerais raras (ou neoformação de fases minerais), como fosfatos com alta concentração de TR e Th, oxi-hidróxidos de Fe, Ba, Mn, e oxi e/ou silico-fosfatos de ETR, Nb, Ta, dentre outros, e a formação de barita. A presença de rochas carbonatíticas com alto P2O5 e o enriquecimento acentuado em TR sugere a possibilidade de mineralizações destes componentes, similar às observadas em outros complexos alcalinos de Goiás e de Minas Gerais, como Catalão e Araxá. A distribuição de elementos menores, traços e TR mostram que as rochas são produtos de alteração de rochas ígneas alcalinas como carbonatitos, lamprófiros e basaltos alcalinos, rochas já enriquecidas em elementos como Th, U, TR (principalmente em ETRL), Nb e Ta. Os teores anormalmente altos são resultado do processo de enriquecimento supérgeno (processos de intemperismo como silicificação e laterização) e/ou alteração hidrotermal com baixa temperatura.

Geek goddesses go to school : A study of female pre-service teachers in information technology courses

Various reasons have been proffered for female under-representation in tertiary information technology (IT) courses and the IT industry with most relating to cultural moirés. The 2006 Geek Goddess calendar was designed to alter IT’s “geeky image” and the term is used here to represent young women enrolled in pre-service IT teaching courses. Their special mix of IT and teaching draws on conflicting stereotypes and represents a micro-climate which is typically lost in studies of IT occupations because of the aggregation of all IT roles. This paper will report on a small-scale investigation of female students (N=25) at a university in Queensland (Australia) studying to become teachers of secondary IT subjects. They are entering the IT industry, gendered as a “male” occupation, through the safe space of teaching a discipline allied to feminine qualities of nurturing. They are “geek goddesses” who – perhaps to balance the masculine and feminine of these occupations - have decided to go to school rather than into corporations or government.
