In addition to cyanide processing, gold ore is also processed with gravity separation. Advanced technology has enabled the amount of,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 slurry.6 Stages of the Mining Process | BOSS Magazine,22/06/2018· From there, the ore is transported to a separate facility for smelting, which is: The process of melting the ore concentrate in a furnace to separate the metal.
