Ore processing is a 24 hour operation Ore is stockpiled (1) at the processing plant and the process begins by feeding the ore into a hopper with a loader The ore is conveyed and lime is added (2) to raise the pH of the ore Following crushing through a jaw crusher (3) the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls The grinding process
Cyanide Processing Equipment and Plant Configuration Options Gold processing equipment example Cyanide solutions may be introduced from the bottom and allowed to percolate upwards or fed from the top and allowed to seep downwards Usually the strongest cyanide solution with the required dissolved lime is added first followed by Get Price Active Lime Plant Capacity 150-600TPH Cement
2 2 Goldcopper ore processing This topic has been thoroughly reviewed most recently by Jay 2001 and Sceresini 2005 hence the focus here is on the main challenges presented by copper contamination of gold cyanidation circuits 2 2 1 Leaching The major challenges to the processing of goldcopper ores using cyanidation is that of the high cyanide consumptions that are typically
The cyanide process of gold recovery enabled a higher percentage of gold and silver to be extracted from hard rock making many operations viable that would otherwise have had to close The world class Martha Mine has a history spanning three centuries Together with its historic use up to 1952 the Waihi mining operations have used cyanide since modern operations began in 1988 A substantial
