Ore processing – Waihi Gold

Ore processing consists of the following stages: crushing and grinding of the ore addition of process water (generally decanted from the tailings pond) to form a slurry addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver into Get price

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. Get price

How to Refine Silver

2017/3/28When refining silver you want to make sure you do this outside where there is plenty of ventilation. Give yourself plenty of room in order to have a quicker dissolving reaction from the silver. Depending on how much silver you have to refine will depend on how many 5 Get price

Truesilver Ore

Only around 30% of output comes from so-called primary silver mines, where silver is the main source of revenue. This is noteworthy given that the impact of the price of silver is most acute on primary silver production, whereas by-product silver production is in large part a function of the price of the other metals, with which silver is mined. Get price

Iron Ore Smelting Process

The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being Get price
