Washing the ore can remove many soluble minerals, some of which may interfere with the leaching operation. One must be careful not to wash any of the gold from the ore. If the ore is to be concentrated, then washing need not be attempted, since the concentration itself will wash the ore.

【Process Introduction】 Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from lowgrade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the goldcontaining solution is leached.

In contrast, gold extraction from the oxide ore in a solution containing 20 g/L iodide and 4 g/L iodine reached 77% in 6 h and 89% in 24 h. With iodate as the oxidant, no gold could be leached in 48 h. When the iodate was partially converted to iodine by adding HCl to the solution, gold leaching was then started.

A. Processing of Oxide Ore. Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (waterbased) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning.
