the process of gold extraction

Determination of Gold in Geologic Materials by Solvent Extracti n and Atomic-Absorption Spectrometry Huffman, Jr., J. D. Mens'ik, and L. B. Riley ABSTRACT The two methods presented for the deter ination of traces of gold in geologic materials are the Extraction of Gold, Gold Extraction Process, Gold Ore Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.

2016/4/6Unfortunately, gold cyanidation was ineffective on refractory gold ores – which are made up of sulfide minerals that block the cyanide solution extracting the gold. An older, and very hazardous, extraction process called roasting was adapted and improved to work with this type of gold ore.
