Gold. In-situ leaching has not been used on a commercial scale for gold mining. A three-year pilot program was undertaken in the 1970s to in-situ leach gold ore at the Ajax mine in the Cripple Creek district in the US, using a chloride and iodide solution.
These veins may be gold-enargite or base metal-Ag dominant and can locally be traced to the paleosurface. Sinter and subsinter hot-spring deposits containing cinnabar and/or sulfur are characterized by pervasive leaching of the rock leaving only residual silica (opalite).

Bob Segall/13 Investigates. Lead is considered toxic and it's a key ingredient in millions of dinner plates, cereal bowls and other dishes we use every day. Federal regulators say, in most dishes, the lead poses no health risk, but some local health officials say the high amount of lead found in many dishes is "too risky" and shouldn't be permitted.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different .
Counter-current leaching. leaching efficiency can be enhanced by the application of Le Chatelier's principle. In summary, the lower the concentration of gold in solution, the greater the driving force for gold dissolution to occur, although in a mass transport controlled reaction it is debatable what role this plays in gold leaching.

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents .
What happens to arsenic during cyanidation depends what form it is in; Stibnite, orpiment, arsenopyrite, realgar. If arsenic is present, regardless of what form, solubility increases with higher pH. Environmentally; during or after detox, the arsenic can be precipitated via ferric sulphate leaching to produce the highly insoluble ferric arsenates which will settle, sometime requires the use of .
