Elaboração de uma cartilha para ensaios de flotação em bancada para o minério de cobre sulfetado na Mina do Sossego

Abstract

This work was to develop flotation tests on benches in order to verify the behavior of the flotation process for a particular ore and other copper sulphide ore sample of it, however contaminated with talc, both samples are from a project mining in the southeastern state of Para for the tests were made between different types of blends of contaminated samples of ore and ore free of contaminant that is already being processed by the processing plant project. All tests were done in duplicate to ensure reliability and reduce the errors of the results. The ore samples were homogenized, Wednesdays, ground in a rod mill, float in a rougher stage, filtered, rowing in a ball mill, float in one cleaner stage, filtered again and sent to be analyzed by the chemical laboratory of the company. The entire methodology, results and other relevant issues on the practice of flotation benches were discussed in this paper.
