Circuito Rougher da usina de Sossego: caracterização da recuperação metalúrgica

Abstract

This work approaches a study developed in a vacation stage on Vale, from January to February of 2008. Specifically at the Copper Mill of Sossego located at Canaã dos Carajás-PA. This paper is based on a metallurgical characterization in rougher circuit, one of the first steps of froth flotation ore at the cooper mill of Sossego. This way, it was possible to get more information about the capacity of cooper and gold flotation ore. Considering sampling of concentrate, reject and feeding. Besides samples were sent to a process laboratory, where they could be filtered with a filter the vacuum, dried in greenhouse, homogenized, quarteated with a quarteater, separated in a main and hided sample, identified and sent to a chemistry laboratory. So it was possible to note the substances’s text indicated more flotability in initial tank cells of rougher circuit.
