Copper Ore. Copper ore usually contains about 0.5 to 2% copper that occurs in the form of disseminated and stringers. The run of mine ore is reduced from 150 mm to 25 mm size in Jaw and Cone crushers. The crushed ore is grinded in ball mills to −74 μm size. The ore is processed by froth flotation comprising rougher and scavenger cells.
Copper (Cu) ore is a naturally occurring mineral deposit that contains copper in varying concentrations. It is an important industrial metal that has been used by human civilizations for thousands of years due to its excellent electrical and thermal conductivity, high ductility, and resistance to corrosion. Copper is widely used in various …
Cyanide solution percolates through the heap leaching the gold and silver and is collected on the pregnant solution pad. The ore is crushed to a size that will give good liberation of gold minerals. In most operations with this crushing stage, the ore is crushed until two-three inch. A finer size can be considered if the ore needs fine liberation.

Crushing is an important step in comminution that prepares the ROM ore for primary grinding and other downstream processes such as heap leach. The selection of the right crushers and crusher flow sheet is dependent on the upstream mining method and blasting characteristics and the downstream process requirements.
The RGO flowsheet consists of primary single toggle jaw crushing of the ore followed by secondary cone (600 kW) and tertiary cone (600 kW) crushing. The coarse crushed stockpile has a 48,000 tonne capacity equivalent to two days operation. Bowl and mantle changes occur every month. Figure 2: Block Flow Flowsheet

Crushing and grinding The first stage of the treatment process is the size reduction of the ore particles down to a size giving liberation of the gold/mineral particles. Typically this can incorporate crushing and grinding – however the emphasis needs to be in minimising fines production prior to the gravity concentration stage.

CRUSHING PLANT DESIGN The number of crushing stages necessary to reduce ore to the proper size varies with the type of ore. Hard ores like gold, iron, and molybdenum ores, may require as much as a tertiary crushing. To design a good crushing plant one has to follow these three steps: 1. Crusher selection 2. Crusher layout and 3.
In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it.
