Amalgamation Process Gold Technology Industry Of Gold Mining

The processing of goldmaking Amalgamation is a process of extraction of gold in rocks containing the gold content of ore by using a chemical binder Mercury (Hg) as a catcher ore minerals. This amalgam process is the most simple and cheapest is usually used by smallscale miners, but on a large scale is not very effective and very expensive.

Gold extraction

Gold extraction

Gold extraction. Once the ore is mined it can be treated as a whole ore using a dump leaching or heap leaching processes. This is typical of lowgrade, oxide deposits. Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and ores resistant to cyanide leaching at coarse particle sizes,
