The Canadian company Rupert Resources owns the Ptavaara Gold Mine, which temporarily stopped operating in 2014. Finally, the Australian company Dragon Mining is also active in Finland, operating the Vammala processing plant using gold ore from the Jokisivu and Orivesi gold mines. Southeastern Europe is an interesting region for gold ore mining.
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
Cyanide method has a history of more than 200 years since it was used in extracting gold and silver in 1887. With the high recovery rate, strong ore adaptability, fast extracting speed, cyanide method is still one of the main gold extraction methods. 4 Extraction Processes for GoldPyrite Ore Goldpyrite ore is a simple sulfide goldbearing ore.
A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of .
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 reduces the rock to a slurry.
Gold in placer mines is usually mixed with a large amount of ore. The task of placer gold beneficiation is to separate gold from a large amount of mixed gravel to ensure a higher metal recovery rate and better economic benefits. The heavy minerals associated with placer gold can be arranged as follows according to the common degree: magnetite, ilmenite, rutile, garnet, zircon, pyrite. JXSC ...
