Ore processing Waihi Gold
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 reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself.

Gold Extraction Method 3. Cyanidation
Gold Extraction Method 3. Cyanidation. 3. Cyanidation Since 1887, cyanidation was used in mining for gold and silver extraction and the technology is mature now. Because of its high recovery rate, good adaptability for minerals and on site gold extraction, the cyanidation method is still one of the main gold production method.
gold milling cyanidation jvandendries.nl
Processing Gold by Cyanidation Leaching. Processing Gold Ore by Milling by Cyanidation Oxide, transitional and deep transitional ores (high grades) will be processed in the Gold Mill plant according to their content of CuCN, %SS, gold and silver. Run of mine is transported from the pit by trucks and deposited on the crusher feed Hopper.
Gold cyanidation is a hydrometallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex. It is the most commonly used leaching process for gold extraction. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents approximately 13% of cyanide consumption globally, with the remaining 87% of cyanide

Gold Extraction Method 3. Cyanidation
The cyanide method can be mixing cyanide and percolation cyanide. Mixing cyanide is for the processing of tailings after gravity separation and amalgamation or the gold bearing concentrate after flotation, or used for all slime cyanidation; however the percolation cyanide is for the processing of flotation tailings and low grade gold bearing ore heap leaching.
