Leaching of a lowgrade, coppernickel sulfide ore. 1. Key .

This study was prompted by the disparate recoveries of nickel (>70%) and copper (<20%) from a test heap of coppernickel sulfide ore after about 200 days of leaching. Variables tested in bioleaching columns charged with a pyrrhotiterich, chalcopyrite and pentlandite ore were acid preconditioning, inoculation and aeration. The results indied

Crushed Ore Agglomeration and Its Control For Heap Leach Operations

This paper attempts to provide a concise overview of available quality control and characterization tools for crushed ore agglomeration with industrial examples from the gold, copper, nickel and uranium operations. Consequently, different agglomerationheap leaching systems and their differences are summarized.

Experimental evaluation of a mineral exposure model for crushed copper ores

Copper mineral inclusions dispersed in crushed ore particles have a certain size distribution (grainsize distribution). For efficient heap leaching processes, the crushing plant should be designed and operated to crush the ore to an appropriate particlesize distribution so that copper mineral grains are exposed and can be leached.

Leaching Process

The leaching process example includes the leaching of bauxite or Al2O3 . 2H₂O with the concentrated and heated sodium hydroxide. The concentrated NaOH here tends to dissolve the aluminium present in the given bauxite, while on the other hand, the impurities like SiO2, TiO2, and Fe2O3 do not get dissolved.
