Ore Crushing and Grinding. Ore crushing and screening, grinding and classification are essential preparatory work before separation to get proper ore size. There is a balance to keep proper ore size neither too rough (insufficient liberalization) and too fine (over-crushed) in order to achieve high recovery rate and high efficiency.
The present invention embodies a process for extraction of nickel, cobalt, and other metals from laterite ores by heap leaching, and of the product obtained as well, characterized by the fact that it is comprised of crushing (I), agglomeration (II), stacking (III), and heap leaching (IV) stages, with this last stage being a continuous, counter-current, heap leaching system with two or
