PRESSURE LEACHING a "medium" temperature process where sulfides were oxidized at 150o C and approximately 1,400 kPa using oxygen.Its' success resulted in the construction of an additional plant at the Flin Flon mine (1993).A major revolution in gold processing was the pressure oxidation of refractory,pyritic ores.In these ores,gold is chemically Mining and Refining Process Beneficiating ore also reduces the amount of material that needs to be transported and processed at the refinery.However,the benefits of beneficiating need to be weighed against the amount of energy and water used in the process and the management of the fine wastes produced. Gold Smelting Process Sciencing The first step in the gold smelting process occurs when ore containing gold is mined from the earth.At this point,the crude binding matter and the gold metal need to be separated.This is accomplished by pulverizing or crushing the gold ore,and then placing it in a furnace. How Is Gold Extracted From Gold Ore? Sciencing Gold is usually found alone or alloyed with mercury or silver,but can also be found in ores such as calaverite,sylvanite,nagyagite,petzite and krennerite.Most gold ore now comes from either open pit or underground mines.The ores sometimes contain as little as 5 100 of an ounce of gold per ton of rock.In.
