Three Kinds Of Copper Ore Beneficiation Methods. There are many types of copper ore. China’s mining is mainly chalcopyrite, followed by chalcocite and bornite. In addition, there are natural copper, tetrahedrite, azurite, malachite and so on. So far, more than 280 copper-containing minerals have been discovered.

Copper is one of the most useful metals .Copper ore beneficiation is a process to extract copper from raw ores. Copper ore is an ore which can produce copper metal by crushing it in ore crushing plant, grinding it in Ball mill and then smelting it in a furnace along with a piece of tin ore. Xinhai Mining Machinery is a professional manufacturer

It is reported that more than 90% of non-ferrous metal ores (copper, lead, zinc, etc.) adopt flotation process, especially for those with fine grain and complex symbiosis. Flotation process can achieve ideal separation effect, and separately recover low-grade ore then enrich multiple high-grade concentrates.

In the world, from the point of beneficiation process, the copper ore deposits can be divided into the following main types [3, 4]:
the Most Renewable ore Resource in the world-copper. Copper is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; an exposed surface has a reddish-orange tarnish. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys.

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, and 4) electrolysis. Following mining, transporting, and crushing to a consistent gravel or golf ball-size, the crushed ore is further processed at a mill

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.

Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm. Copper ore crushing process. 1.

In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.

Therefore, the flotation of pyrite has an important influence on the entire beneficiation process. In addition, before the extraction of copper from sulfide ore, you must first determine which type of ore the copper-sulfur ore is, and then select the appropriate process based on the multi-element analysis report and the grain size of the sulfide.

Ore crushing and screening, grinding and classification are essential preparatory work before separation to get proper ore size. There is a balance to keep proper ore size neither too rough (insufficient liberalization) and too fine (over-crushed) in order to achieve high recovery rate and high efficiency.
