MATERIALS BALANCES IN GOLD PROCESSING PLANTS

Jan 01, 1987· SAMPLING GOLD PROCESSING PLANTS The basis for all materials balance calculation is the extraction of data from the process. Seme of the data can be obtained as solids or liquids flowrates, through the use of instruments in the plant, but most information is derived frcm the ex traction of samples and their analysis.

CIL gold processing plant CIL processing plant for sale

CIL gold processing plant mainly consists of following steps: 1 The ore is first reduced in size (typically 90% passing 200mesh ) to ensure that all non-refractory gold is readily accessible for cyanide leaching, There are several variations of comminution circuits used in the gold leaching industry, such as: Multi-stage crushing, then ball milling circuits, typical of ball mill and hyrocyclones.
