Experimental report on the selectivity of ore in Ningshan Yuxin Molybdenum Mine


The process and condition test of the Ningshan Molybdenum Mine is carried out to solve the problem of low recovery rate of the existing molybdenum concentrate.

This test was sent to a large sample containing 0.432% molybdenum and carbon %. The test sample is a molybdenum-rich high-carbon molybdenum ore, which is also difficult to treat molybdenum ore. The reason is that when molybdenum ore is associated with graphite or “carbonaceous matter” and talc , because of their similar natural buoyancy, neutral oil can float, making molybdenum and “carbonaceous matter” or talc difficult. Separation, especially the separation of molybdenite from "carbonaceous matter" is even more difficult.

The researchers passed a large number of tests, through a variety of pharmaceutical test comparisons, combined with the on-site process and process conditions, and finally determined the use of a coarse, two sweep, nine fine process, to obtain molybdenum concentrate containing 42.47% molybdenum, molybdenum recovery 85.95%, the test achieved the intended purpose, which provided a reference for the Ningshan molybdenum mine to improve the current plant molybdenum recovery rate.
