Levantamento de parâmetros físicos em colunas de extração mineral

Abstract

The oxidized copper ore of Canaan has been stored since the beginning of the extraction of copper sulphide ore. Targeting the best future use of the ore that has been stored, and desiring to facilitate the processing of oxidized copper ore from the mine via the Quiet hydrometallurgical route. Preliminary tests were carried out in vertical columns of mineral extraction in laboratory scale, flow in porous media with the ore beds: crushed, crowded, crowded with crushed. Rose physical parameters such as porosity, integrity particle residence time of the fluid density and fluid flow, to provide data for future adaptation of a model capable of performing the physical control of the operation, and assess the results of the three samples for operational optimization. The results of this study showed that it is possible to control the solid-liquid contact column and also the influence of porosity on fluid flow in the test samples. The parameters measured showed that among the three studied samples, which was tested with a mixture of two kinds of material (crushed and crowded) is the most suitable for application on an industrial scale, taking into consideration the economic and operational.
