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.
Copper concentrate dryer machine is the special machine used for drying common metal ores; it has the advantages of high drying efficiency, fast speed, and strong continuous operation capacity. Its drying effect is remarkable for the industry ores such as copper concentrate, hematite, etc.The machine is consisted of two parts: round concentration pond and harrow mud scraper. Solid particle suspending in the slurry precipitates with gravity. Upper part is clear water, which flood from the top overflow wire, the bottom sedimentation slurry will be scraped to discharge mouth at the center of the bottom by harrow mud scraper, thats the concentration process. The slurry with certain thickness continuously flows at determined rate to concentration pond, the mud scraper runs stably to scrape the pulp. So the concentrator is long-term continuous working dehydrating water equipment.
The discharge concentration depends on concentrated materials density, particle size, mineral components and time period in concentration pond. Middling ore with density of 2.82.9t/m3 can be concentrated to 30%-50%, and concentrate with density of 4-4.5 t/m3 can be concentrated to 60-70%. When the concentrator is used for dehydrating water, its product is clean water, the solid content of it below 0.5%, and the discharged mud index is 20%30%.
