PARTING: Separate Gold and Silver by Melting

Parting is the separation of silver from gold and a process during which the base metals are separated from both, but, as the presence of a high percentage of these base metals is injurious to the successful conduct of the processes which are chiefly in use, a preliminary refining by one of the methods already described is usually necessary.

Crushed ore agglomeration and its control for heap leach …

Crushed ore agglomeration. Crushed ore agglomeration has two major aims. First, it is the best opportunity for the thorough application of the leaching solution prior to building the heap and "kick starting" the leaching process itself (Bouffard, 2005, Dhawan et al., 2012a, Kodali et al., 2011a, Purkiss and Anthony, 2004).

Gold Extraction & Recovery Processes

The ore is crushed to a size that will give good liberation of gold minerals. In most operations with this crushing stage, the ore is crushed until two-three inch. A finer size can be considered if the ore needs fine liberation. The leach cycle is normally from 20 to 30 days. When the leaching cycle is complete, a new crushed ore is piled.
