Gold Extraction Process - Know How Gold Is Mined

2021-6-29  The process used to extract gold involves strategically drilling and blasting rocks. Plans laid out by engineers and geologists prior to mining take a lot of preparation and often show the precise position of the gold within the rocks. As a result of this, miners are able to extract large quantities of gold-laden rock, referred to as the ore.

The Extraction of Gold from E-waste by Hydrometallurgy

2015-3-31  Wong, et al used hydrometallurgy to extractvaluable metals like gold, silver, selenium, telluriumfrom copper anode sludge. In this method, anodesludge without copper is used to extract silver,selenium, and gold. First, anode sludge withoutcopper is leached into a roughly 4-9 molar nitricacid at 40-115 degrees Celsius. Silver, selenium,and tellurium are dissolved in this situation; the wasteleached into nitric acid is processed at a hightemperature between 40 to 110 degrees centigradewith aqua regia to dissolve gold. At this level, gold,arsenic, antimony, lead, tin, smooth, platinum groupmetals and small amounts of silver are leached.The leached solution is separated from the wasteand then gold, using extraction technique withsolvent recovery and then organic phase containinggold and 2 molar or more choleric acid as detergentsolution, is extracted from other impurities. Oxalicacid is used to remove residue and extract goldfrom organic extractor charged with gold.
