Jan 23, 2012#0183;#32;Step #7 Processing (onsite) Once ore is extracted, processing it into pure gold must be done. Ore is first crushed and then undergoes various processes depending on the nature of associated minerals. Processing lowgrade ore is relatively simple while higher grades require more extensive processing. Step #8 Refining (offsite)
In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the casting functions as a positively charged

Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

The reaction which takes place may be represented as follows: 2Ag + 2H2 SO4 = Ag2 SO4
In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride. Under the influence of an electric current, the gold migrates to a negatively charged
Pouring the acid into a coffee filter the acid passes through the filter leaving the gold behind, save the acid do not dump it down the drain. Next dump the remaining fingers and circuit boards into a deep plastic tray and add water, sort out the cleaned of gold parts, put the cleaned parts in the waist and save the uncleaned parts for redipping.
The raw ore of this mine is quartzite gold mine, which is most oxidized ore or original minerals with low sulfur content. Therefore the processing technology is combined gravity separation and allslime cyanidation carbonleaching technology, which realizes the high efficiency recovery of gold. The production cost saving is up to 15%.
Cornstarch Replaces Cyanide In Clean New Gold Extraction Method. Scientists accidentally discover a new way to isolate gold that is much safer than existing processes, which use toxic cyanide.
The main metal minerals in a goldbearing quartz mine in China are galena, chalcopyrite, pyrite, native gold, and gangue minerals are mainly quart. In the flotation gold extraction process, sulfurous acid and lime are used as inhibitor, copper sulfate as activator, ethyl xanthate and butyl xanthate as collectors and pine oil as ing agent. The dosage of every agent is 15g/t of the pine oil, 130140g / t of xanthate,
CHRISTOPHER A. FLEMING, JAMES A. BROWN SGS AND MARIUS BOTHA. ABSTRACT. The technical and economic feasibility or reprocessing hundreds of millions of tons of tailings in a number of historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate

addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver into solution; addition of carbon to adsorb (attach) dissolved metals and remove them from the slurry; stripping the metals from the carbon by acid washing and circulation of a caustic cyanide solution; precipitation of the gold and silver by electrowinning
