the mercury is applied on an ore, picks up the gold, and the resulting amalgam is distilled, with the mercury being boiled off to remove it. mercury is highly toxic and therefore environmentally sensitive, making the industrial plant to perform this type of extraction expensive. the most important purification process in gold mining is cyanidation.
mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. using todays compact mining equipment, copper ore is extracted from the mine. after the ore is crushed, its roasted, which helps to convert sulfides to oxides.
types of ore. the standard cyanide leach process consists of grinding the ore to about 80% 200 mesh, mixing the orewater grinding slurry with about pounds per ton of sodium cyanide and enough quick lime to keep the pH of the solution at about 11.0. At

the gold mining process. In addition to cyanide processing, gold ore is also processed with gravity separation. advanced technology has enabled the amount of gold mined and processed to steadily increase over the years. for example, the worldwide production of gold in 2006 was 2360 metric tons. As of 2013, that number had climbed to 2770 metric
jan 23, 2012 As you can see, the process of taking metal ore from the earth and converting it to gold bullion is quite extensive and requires a lot front-end investment and time. In the end though, we get these shiny coins and bars to enjoy. gold miners too take special care to make the impact of mining for gold as light as possible.
ore processing. ore mined is treated and smelted at mponengs gold plant. the ore is initially ground down by means of semiautogenous milling after which a conventional gold leach process incorporating liquid oxygen injection is applied. the gold is then extracted by

extraction of gold and other precious metals from their ores by treatment with mercury is called amalgamation. gold dissolves in aqua regia, a mixture of hydrochloric and nitric acids, and in sodium or potassium cyanide. the latter solvent is the basis for the cyanide process that is used to recover gold from low-grade ore.
amalgamation is accomplished by passing a slurry of ore over copper plates coated with mercury, by mixing a slurry of ore and mercury in a cylindrical or conical vessel called an amalgam barrel, or by grinding the ore in a ball, rod, or pebble mill to free the gold from the mineral matrix and then adding mercury to the mill and continuing grinding until the gold has dissolved in the mercury.
finding new mineral reserves is critical to the success of our company. locating, extracting and processing these natural resources is a multi-year process that involves complex scientific, environmental and social planning.
