The Basics of Gold Mining and Processing. If the gold is located close to the surface, it's mined with openpit mining techniques. Gold that's located farther below the surface is collected with underground mining methods. Large pieces of ore are made into smaller pieces, and then the sand grainsized pieces are mixed with a cyanide solution to create a watery, mudlike mixture.
Diamond Processing Flow Chart #3. The concentrates are fed to spread a thin layer over the belt surface down which a stream of water flows. Grease is continually applied to the belt at the upper end and is scraped off at the lower end with the diamonds. The diamonds .
Beneficiation of Iron Ore. This also applies to iron ores of the nonmagnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500mesh for liberation of the iron minerals from the siliceous gangue.

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 lowgrade ore.
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 small gold nuggets and flakes. Placer mining techniques .
