Jan 18, 2017· Many people confuse gold smelting with melting. Whereas gold melting is simply heating gold to turn into a liquid form before forming gold bars, smelting is a more complex process that involves the removal of impurities from gold using heat, pressure and a number of chemicals. History of Gold Smelting . The smelting of gold is not a new process.
Then the gold is smelted into doré bars, which are a semipure alloy of gold that will be refined further into pure gold. The ore processing facility will have the capacity to process approximately 7,000 tons of ore per day, yearround. We expect to unearth up to 130,000 to 150,000 ounces of gold per year.
To conduct our business and produce gold, certain inputs such as orebearing resources, people and machinery are required. We invest in skills enhancement, technology development and application, and in prospecting for and developing our mineral resources and ore reserves, to ensure the economic viability and sustainability of our business.

Jul 22, 2019· A mercurygold amalgam then is formed because gold will dissolve in the mercury while other impurities will not. The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold. This process does not result in gold that is pure, but it does eliminate the bulk of the impurities.
