SEVERAL WAYS OF IMPROVING THE METALLURGICAL PERFORMANCE OF ORES FROM JINCHUAN MINE

Jinchuan nickel mine is one of the world-famous large scale multi-metal associated copper-nickel sulfide deposits. It was indicated by research results of a pilot and a commercial test that such measures as adoption of high efficient novel collector-frothers AS, CEED, J-622 etc. developed by our institute, mixed addition of reagents, regrinding of rougher concentrate followed by centralized cleaning, reasonable and suitable ways of dealing with middles were the effective ways of improving the metallurgical performance of nickel ores from Jinchuan mining area No. 2. The research achivements of J-622 commercial test have been applied in practice. In order to supply the high quality concentrate of which MgO content must be low, another commercial test will be achived according to the pilot test results. Remarkable benifit has been and will be gained in Jinchuan Nonferrous Metals Company.
