The project has mainly come about for two main reasons.
Interested in The processes of smelting or roasting your ore to recover its gold and silver? Some fairly rich ores require a lot of work to get all the gold and silver out them. Historically, smelting and roasting of ores have been used to capture the gold from difficult to treat ores.
it is present in many products in everyday use. Antimony’s moderate price of changing common metals into gold. to extract the antimony from these gold extraction from antimony tailings Grinding Mill China. Posted at: August 2, 2012. Gold Extraction Gold Mining Washing, GOLD EXTRACTION.
Oct 17, 2011· Learn how to make more gold with borax instead of mercury. Description of a new environmentally beneign gold extraction method which will make use of mercury for gold extraction redundant.
Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of
Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation, whereby the fusible sulphide is removed from the gangue and concentrated. The concentrate is then reduced to metal by smelting with wrought iron in pots, in reverberatory furnaces or sometimes in blast
Some antimony is produced as a by-product of smelting ores of other metals, mainly gold, copper and silver, in countries such as the United States, Canada, and Australia. Important amounts of antimony are yielded as a by-product of copper and silver mining. Numerous stibnite deposits occur in
Improved gold and silver extraction from a refractory. Improved gold and silver extraction from a refractory antimony ore by pretreatment with alkaline sulphide leach. temperature and concentrations of Na 2 S and NaOH on the removal of antimony and the extraction of gold and silver in subsequent cyanide leaching were investigated.
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%.

Antimony-bearing sulfide gold ore refers to the antimony-bearing sulfide or gold ore in which antimony minerals exist independently. This type of ore is generally difficult to be extracted by amalgamation and cyanidation directly, so flotation, roasting, and cyanidation gold extraction processes are often used to extract this type of gold.
Antimony Ore any of the natural mineral formations containing antimony in compounds and concentrations that make commercial use technically and economically feasible.
