Reasons for Copper Ore Sorting cont. • Preconcentrate feed into highgrade and lowgrade stockpiles: – Optimize multiple process streams send ore to either mill, heap leach or smelter. – Allows smaller mills to be built or increase capacity of an existing mill. – Manage ore blending programs more effectively.
The main copper sulphide minerals are chalcopyrite (CuFeS2) chalcocite (Cu2S), covellite (CuS), bornite (Cu5FeS4), tetrahedrite ((Cu,Fe)12Sb4S13) and enargite (Cu3AsS4). The largest source of copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs.
An example where copper is further purified is at the Asarco electrolytic plant in Amarillo, Texas. The 99% pure copper from the anode furnace is cast into 750pound, 3inch thick, rectangular slabs called anodes. The final step is a process called electrorefining.
Iron Ore Concentration Process . Magnetite is mined in large chunks and is crushed into small particles by a series of crushers. After primary crushing with jaw crushers and secondary crushing with gyratory crushers and tertiary crushing with cone or high pressure grinding rolls (HPGR), the ore is screened on vipating screens to size the particles.
Grinding is the last stage in comminution. In this operation, ore particles are reduced and classified (typically in a hydrocyclone) into a uniformly sorted material between 20 and 200 mesh. Most copper facilities use a combination of rod and ball mills to grind sulfide ore (Figures 16a and b).
Concentrating Some ore types can be treated by crushing, grinding and mixing ore with water to produce slurry. The coppercontaining particles are then removed by a process called flotation. The product of this process is dry, gray powder called copper concentrate, which contains about 30 percent copper.
Copper Ores and Copper Mining Process September 18, 2015 02:40:05 PM Copper Ores. Copper occurs in two different mineral groups: sulfide ores, oxide ores (carbonate minerals and silicate minerals), and both ore types can be economically mined.
copper ores by a flotation process, that are copper content in the feed, concentrate and tailing, and three generated upgrading parameters, that are concentrate yield, Cu recovery in concentrate and nonCu components recovery in tailing.

percent copper in the concentrate, concentrating 1 ton of copper ore requires over 200 billion Btu, or approximately 42 million Btu/ton of cathode Grinding accountsfor roughly 6 0 percent of the total energy consumed in processing, and crushing 12 percent. Pumping new
TENORM: Copper Mining and Production Wastes Within the United States, mining and production of copper are primarily located in the West, specifically Arizona, New Mexico, Utah, Nevada and Montana. According to the United States Geological Survey (USGS), production in these states and Michigan account for more than 99% of domestic copper production.
Preconcentration in this early stage produces a higher grade feed stream which often enables more flexible downstream processing options. with over 80% of the gold and copper concentrated in less than 40% of the mass below 20 mm ( Curve and Preconcentration Methods distribution can be performed by simply employing a screening process. preconcentration involving optical and xray .
