Some Characteristics about the Mining Copper Ore
3 August, 2013 at 6:30 am in Construction
At present, the raw materials to refine copper in China mainly are towanite, chalcocite, bornite, malachite and etc. So many mining manufacturers are just producing the mining machines on the basis of the traditional machine with the outdated mechanism and technology, which cannot get rid of the passing history on the updating and innovation of jaw crusher which has been making a big difference to the whole society. In Hongxing Machinery, stone crushing machine mainly consists of jaw crusher, impact crusher, cone crusher, hammer crusher, VSI crusher and mobile crusher etc. According to the technical conditions of smelting, the copper ore can be divided into three classes based on the proportion of copper oxide and copper sulphide, that is, sulfide ore, which contains less than 10% copper oxide?oxidized ore, which contains more than 30% copper oxide; mixed ore, which contains 10%~30% copper oxide.
Raw materials of copper ore have the following characteristics:
1? raw materials of copper ore that suitable for smelting are stored in multiple deposit types. Among them, the deposit types of important exploitation values are magma copper nickel sulfide deposit, porphyry copper ore deposit, skarn type copper and polymetallic deposit, Hydrothermal vein copper deposits, Volcanic sedimentary sulfide copper deposits, and Depositional layered ore deposits and etc.
2) The ores are complex ore structures, unevenness disseminated granularity, nonuniform disseminated, mineral assemblage, subtle fabric disseminate, complex composition, and different to dress.
3) Ore chemical compositions are complex, accompanying and inter growing with many beneficial and harmful component, so, its smelting process conditions are very complex.
Ore dressing processes of copper are crushing –ball milling—classifying—flotation—concentrating. For the rare polymetallic ore contain nickel, cobalt, molybdenum and gold can firstly beneficiate copper concentrate then dress nickel concentrate, cobalt concentrate, molybdenum concentrate and gold concentrate by flotation respectively. The copper ore dressing equipments and Iron ore concentrator are the key points of the research and development of our company. The copper ore dressing equipments manufactured by our company contain all the equipments needed in all the stages of crushing, milling, screening, and concentrating. So our equipments can meet the requirements of all kinds of ore dressing production lines assembled by customers.
