Status of foreign copper molybdenum ore beneficiation
Copper-molybdenum ore is one of the main sources of molybdenum, and Chile, the United States, Canada, Peru, Mexico and the Soviet Union, it is the recovery of molybdenum concentrate mainly from copper-molybdenum ore
Countries. Foreign practice shows that in recent years, the mining of copper tungsten deposit, the minimum copper grade of 0.2 to 0.3%, the lowest grade molybdenum 0.01 to 0.011%.
At present, foreign copper-molybdenum ore beneficiation has three characteristics: First, they use a mix plus flotation separation process; Second, the rapid construction of a modern and efficient process large
Type the new plant, only 1975 to 1980 built on flat Tuo Wali plant (36,000 tons / day, the United States), Huo boast the plant (41,000 tons / day, Peru), La Kali
Dade plant (90,000 tons / day, Mexico), plant (40,000 tons / day), Kapuqieshi He ink plant (40,000 tons / day, Iran), Sa
plant (40,000 tons / day), Bagh Dade plant (36,000 tons / day, the United States); third is to strengthen the research molybdenium recovery process.
In order to remove undue impurities, almost all recent construction of copper-molybdenum plant molybdenum rougher concentrate will be multiple choice, usually 7 times to 12 times, and in the fine
Election process, but also after a period or two and then re-grinding mill. Regrinding some open, some closed circuit with cyclones job selection period is closed, the former tailings return once
To mine box. Pima plant 3 to 7 times the combined selection of tailings, grading and re-sent to grind. The plant's molybdenum alloys mixed concentrate of 27% copper and molybdenum 0.5%, also contains a large number of
Talc, which planktonic activity and molybdenite are similar, it is difficult to remove, often resulting in molybdenum concentrate grade of less than 40%, sometimes even less than 10 to 15%, this failed concentrate
In the past had to be stored up for future processing. In order to improve the quality of concentrate, the plant had tried various methods, no problem. 1975 Pima introduction of tungsten ball election
The new law, the law is molybdenum concentrates containing talc in the selection carried directly into the flotation of molybdenum - talc separation. First or mineral acid salt was treated with a weak base (ammonium sulfate)
After a weak acid with a strong base (sodium) salt solution treatment. Featured sent out dehydration of tungsten balls, talc, molybdenum rougher tailings go to the mine boxes. The new process will return molybdenum concentrate
Yield increased from 40% to 43% (ore grade 0.47% Cu, 0.015% Mo). According to reports, the new process is set in the original production site, without the expansion of the flotation
Operating line.
