Cyanide. Yet another gold removal process is ground ore is put into a solution that contains a frothing agent along with a collecting agent and organic chemicals. The frothing agent turns the solution into a . The collecting agent bonds to the gold, creating an oily film that will later attach itself to the surface of air bubbles.
Metallurgical processing of metalliferous ores in general and gold ores in particular, consists essentially of three stages, often colloquially referred to as: Bashing (crushing); Mashing (grinding); and; Hashing (extraction/recovery) In the context of flowsheet selection, the bashing and mashing stages are .

Nov 21, 2008· Extraction Process of Gold (Au) and Silver (Ag) Generally, extraction process of all metal always include the Comminution (Size Reduction)to liberate achieve mineral. The next process of gold extraction from Hydrometallurgy route is Leaching.
The Gold Extraction Process. After that part of the Gold extraction process is complete, the Gold is sifted from the resulting materials and melted down to form a bar, nugget or other solid shape. Gold melting typically involves a crucible and the temperature required to melt it depends on its purity. Pure Gold, or .9999 fine Gold, melts at degrees Fahrenheit.
Industrial Process. Mercury is also extensively used in the gold mining process as an amalgam for separating gold from ore. When mercury is combined with gold silt, it causes a reaction that separates the gold from the ore. This amalgam is then heated in order to .
