Ten Drying Skills Of The Copper Concentrate Dryer
Copper concentrate dryer (ore beneficiation) is a professional machine for drying
commonly used metal ore, drying efficiency, high speed, and continuous operating capability. For commonly used in industrial ores, such as the drying effect of copper concentrate and hematite.
Copper is the metal one of the earliest human discovery and use of purple, specific gravity 8.89, melting point of 1083.4 C Copper and its alloys due to conductivity and thermal conductivity, corrosion resistance, easy processing, good tensile strength and fatigue strength, widely used in the metal material consumption after steel and aluminum, as the people's livelihood and national defense projects and even indispensable in the high-tech fields of basic materials and strategic materials. It entails a wide range of uses in the electrical industry, mechanical industry, chemical industry, defense industry and other sectors. The copper concentrate is low grade copper ore after the beneficiation process processing to achieve a certain quality indicators concentrate for the smelter copper.
At present, our election in smelting and mineral raw materials is mainly chalcopyrite, chalcocite, bornite, malachite, and so on. Smelt technical conditions, the proportion of copper ore to copper oxide and copper sulfide to draw three natural types. Sulfide ore containing copper oxide is less than 10%; oxidized ores containing copper oxide is greater than 30%; mixed ore containing copper oxide 10% to 30%.
The copper minerals raw material has the following characteristics:
A) raw materials of the copper minerals suitable for dressing and smelting production, hosted in a variety of deposit types. Among them, an important mining the value of deposit types: magmatic copper-nickel sulfide deposits, porphyry copper deposits, skarn copper and polymetallic deposits, hydrothermal vein-type copper deposits, volcanic - sedimentary massive sulfide copper deposits, sedimentary layered deposits.
2) ore texture and structure is complex and dissemination size uneven, uneven dip particle size of ore, even a lot of mineral assemblages, fabrics disseminated subtle, complex composition of refractory ore more.
3) ore chemical composition of a variety of associated symbiotic variety of beneficial and harmful components, the complexity of the dressing and smelting process conditions. Currently, the majority of the development of mining integrated copper deposits, associated to a variety of beneficial to harmful elements. Through comprehensive mining and utilization, we can transform variable damage into benefits and turn waste into treasure.
Copper beneficiation process is broken - milling - classification - Flotation - Selected, containing nickel and cobalt molybdenum gold and rare metal ores, the rougher copper concentrate were flotation of nickel concentrate, cobalt concentrate, molybdenum concentrate, gold concentrate.
Selected copper device, select the device of iron ore has been the focus of my factory R & D, production of selected copper equipment includes all equipment such as crushing, milling, screening and selection phase of the needs of, to meet the customer assembly kinds of dressing the needs of the production line.
