Ore processing – Waihi Gold

Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader The ore is conveyed, and lime is added (2) to raise the pH of the ore Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls The grinding process reduces the rock to a slurry9 Step Process for Discovering, Mining & Refining Gold,As you can see, the process of taking metal ore from the earth and converting it to gold bullion is quite extensive and requires a lot front-end investment and time In the end though, we get these shiny coins and bars to enjoyThe 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
