METHOD OF EXTRACTING METALS FROM ORE MATERIAL USING MATERIALBED COMMINUTION AND TANK AND HEAP LEACHING

摘要

In this method according to the invention for extracting metals, starting ore material is subjected to material bed comminution in the grinding gap between two rolls and then leached by the addition of leaching fluid. In order to be able to ensure an optimal yield of metals even in the case of greatly differing particles sizes of the comminuted ore material, the comminuted ore material is divided into oversize material and fine material, whereupon oversize material is delivered to a heap leaching and fine material to a tank leaching.
