At present, the raw materials to refine copper in China mainly are towanite, chalcocite, bornite, malachite and 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 two cones of medium and fine cone crusher are both gentle dip erect frustum cones, and between the two cones, there is a certain length parallel crush section (parallel band), which is used to control the granularity of product, for the design of medium and fine crusher is based on the quality and capacity of crusher.
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. With its high quality products such as Rock cone crusher?Magnetic separator?Combination crusher?Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
