The Mining Process – Waihi Gold
A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.
Gold and Platinum Refining Recovery Systems / Equipment
Add sugar water, which will turn the silver oxide into pure silver. A simpler process of refining silver is electrolytic. Hang your silver in an electrolytic bag and immerse it into a very diluted nitric acid solution.
Gold processing |
By 2000 bc the process of purifying goldsilver alloys with salt to remove the silver was developed. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower. By ad 100, up to 40,000 slaves were employed in gold mining in Spain. The advent of Christianity somewhat tempered the demand for gold until about .

Digging deeper: Mining methods explained – Anglo American
Underground mining is practical when: The ore body is too deep to mine profitably by open pit. The grades or quality of the orebody are high enough to cover costs. Underground mining has a lower ground footprint than open pit mining. The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining.
Precious Metal Refining Process | The Perth Mint
Gold Refining. The dore bar first goes through a chlorine refining process, also known as the Miller process. This involves bubbling chlorine gas through the molten dore metal in which the silver (and most other metals) react with the chlorine to form silver chloride as a slag on top. This process produces gold to a purity of %,...
