Abstract

Language:

The extraction of metal ore in the poor leads us to look for techniques and methods to extract a good amount of it (metal) low cost without passing the gangue in the solution. For this purpose, to determine leaching parameters seen to recover the metal in a low grade ore, we proceeded to test leaching guidelines heap ore preceded by size analysis and chemical different slices to determine the working parameters that can give satisfactory results. After these analyzes guidance, we opted for crushing the ore to determine the correct job settings for a good recovery of the metal contained in the ore poor and know the slice for perfect contact between the etching solution and ore for metal recovery. During testing after leaching, we noticed that when we respect the following parameters: a constant acid concentration of 70 g / l, a time of 64 hours, a particle size of 1,700 micron; we dissolved a good amount of metals or a yield ranging between 37.9 to 74.9% when the particle size of the ore pass 9423-850 micron. However, leaching of the composite sample of the same ore, gives a neighbor leach performance to which is recorded with the fine ore 70.8%.
