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
Copper Mining and Processing: Processing Copper Ores
Sulfide ores are generally processed using pyrometallurgy, the extraction and purification of metals by processes involving the application of heat. This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting
Copper processing Ores Britannica
Mining. For lower-grade deposits located near the surface, the open-pit method is the most practical for the mining of large tonnages of material. Large track-mounted drills prepare the ore for blasting, and the broken ore is hauled to the ore-dressing plant by truck (at up to 150 tons per load) or conveyor.
