copper ore minerals and industry in Chile

In the kingdom of metal, copper's conductivity is just second to silver while it's cheaper and larger-amount than the later. Around the world, it is Chile which owns largest amount of copper and is called ¡°country of copper mine¡±. Chile is endowed with rich mineral resources, especially copper. Chile¡¯s mining sector accounts for 10.1% of GDP(2000) and Chile has used its copper resources to diversify its economy and achieved strong economic performance with agricultural products as star performers. The expansion of the copper sector and copper exports played a key role in Chilean economic development. It has been turned that the copper ore mining equipment in Chile plays an important role in the mining industry.In addition to native copper and malachite,there are also chalcopyrite, bornite, chalcocite,covellite and tetrahedrite, etc.

copper ore mining process and equipment

The initial step of copper ore beneficiation is crushing. Crushing is frequently split into three stages, namely, primary crushing, secondary crushing and fine crushing. To accomplish primary crushing, people usually make use of a jaw crusher or impact crusher. They are able to crush copper ore into more compact dimensions. Thus, these more compact copper ore could be given into mill for example ball mill for grinding. Impact crusher is usually used after jaw crusher, and may crush hard gemstones, not just the copper ore, but additionally other ores for example copper, bauxite, container, Kaolinite, manganese etc.

Secondary crushing: after reaching certain size, the types of materials could be given to grinding mills for more grinding. Generally used grinding mills are ball mill, vertical curler mill, ruthless suspension grinding mill, MTM medium speed trapezium mill and SCM series super thin mill.

After grinding with a ball mill, the copper ore fines are given into spiral classifier. Through the principle of various solid contaminants have different sedimentation rate in liquid, spiral classifier cleansing the combination of ore and certifying them.

After washing and certifying, mineral mixture were given in to the magnetic separation. Because of the various susceptibility of numerous minerals, magnetic and mechanical pressure can separate the magnetic material in the mixture materials.

Flotation separation: The process accustomed to separate copper and metal sulfides in the gangue. Oxygenation from the milled slurry, and adding specific chemical reagents, encourages froth formation, while activators are put into promote flotation of copper-bearing compounds. The froth that floats towards the surface consists of the majority of the copper and copper sulfides, and it is removed for more treatment. These components is called the concentrate. After magnetic separating, minerals contaminants were delivered to the flotation separation. Now, put in different chemicals based on mineral qualities, so that you can result in the minerals along with other substances to become separated.
