Description
Technical field
The present invention relates to a kind of flotation separation method of mineral, particularly the method for the high charcoal nickel-molybdenum ore of a kind of flotation.
Background technology
High charcoal molybdenum nickel minerals be in the 60's along unique bedded molybdenum deposit of finding black shale in the lower Cambrian in ancient basin, Yangtze River in China south, it is different from traditional nickel sulfide, sulfuration molybdenum ore.The main feature of high charcoal molybdenum nickel minerals is high containing charcoal, except containing molybdenum, contain the rare precious metals such as association vanadium, phosphorus, copper, lead, zinc, uranium, platinum and palladium, there is very high value of exploiting and utilizing, and high charcoal molybdenum nickel minerals reserves are very abundant, mainly be distributed in the ground such as Hunan, Guizhou, Yunnan, only the high charcoal molybdenum in Xiangxi Region, Hunan Province nickel minerals reserves are more than 10,000,000 tons.
High charcoal molybdenum nickel minerals is high containing charcoal, ore properties complexity, and ore dressing difficulty is very large, reclaiming at present high charcoal molybdenum nickel minerals dressing and smelting process and be picking, roasting, alkali soaks and reclaims molybdenum and obtain ammonium molybdate, its PROCESS FOR TREATMENT cost is high, and the rate of recovery is low, can only reclaim containing molybdenum higher than more than 3% high-grade molybdenum ore.Low-grade molybdenite is less than 1.5% containing molybdenum, and traditional dressing and smelting process is processed loss of capital, cannot reclaim, and can only low-grade high charcoal molybdenum nickel minerals grade be enriched to more than 3% by ore dressing mode, smelts recovery.
In high charcoal molybdenum nickel minerals ore dressing process, due to the suction-operated of carbonaceous thing, first can make molybdenum nickel floating agent dosage become large, exceed the more than two times of floating agent conventional amount used, make mineral processing index variation simultaneously, beneficiation cost increases; Secondly, in refining process, carbonaceous thing can make the floating agent desorption of object mineral surfaces absorption, must in refining process, add medicament, causes concentrate grade to reduce, and beneficiation reagent consumption increases; Again, extremely strong containing the carbonaceous thing surface hydrophobic of organic charcoal, be difficult to suppressedly, cause molybdenum, nickel ore concentrate grade to reduce, the content of silicon and aluminium raises, and increases smelting cost.
High charcoal molybdenum nickel minerals ore properties complexity, flotation difficulty is very big, and less about high charcoal molybdenum nickel minerals flotation research both at home and abroad, the flotation of existing high charcoal molybdenum nickel minerals mostly adopts and first removes carbonaceous thing, the method for rear flotation nickel molybdenum, the method flotation time is long, and mineral processing index is poor.Therefore, develop a kind of inhibitor that can effectively suppress carbonaceous thing, simplify high charcoal molybdenum nickel minerals mineral processing circuit, shorten molybdenum, nickel flotation time, improve mineral processing index, be of great practical significance and far-reaching significance for flotation and even other flotation containing charcoal mineral of high charcoal molybdenum nickel minerals.
Summary of the invention
The technical problem to be solved in the present invention is to provide and a kind ofly also provides to the good inhibitor of carbonaceous thing inhibition the method for floating that uses this inhibitor, to realize the efficient flotation separation of high charcoal molybdenum nickel minerals, obtains good floatation indicators.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: carbonaceous thing inhibitor for high charcoal molybdenum nickel minerals flotation molybdenum nickel, the component that this inhibitor contains following parts by weight: 40～120 parts of acid oranges, 60～180 parts of CMC of 20～60 parts of ethyl tert-butyl ether (ETBE)s.
The method that uses the high-carbon molybdenum-nickel ore flotation molybdenum nickel of above-mentioned carbonaceous thing inhibitor, this method for floating comprises the steps:
(1) ore grinding: high charcoal molybdenum nickel minerals is milled to granularity and is less than 200 objects and accounts for 70%～88%.
(2) molybdenum nickel flotation: through 1～2 molybdenum nickel roughly select, selected and 1～3 the molybdenum nickel of 2～4 molybdenum nickel scans and obtains molybdenum nickel ore concentrate and molybdenum nickel flotation tailing; During described molybdenum nickel is roughly selected, raw ore per ton adds ore pulp to adjust 300～800 grams of sodium carbonate of dispersant, 600～2000 grams of waterglass, 120～360 grams, carbonaceous thing inhibitor, 40～150 grams of collecting agent kerosene, 30～240 grams of foaming agent MIBC.During described molybdenum nickel is selected, each selected 10～100 grams/ton, carbonaceous thing inhibitor that adds; During described molybdenum nickel is scanned, scan at every turn and add respectively 10～70 grams/ton of kerosene.
(3) nickel molybdenum flotation: roughly select through a nickel molybdenum, selected and 1～3 the nickel molybdenum of 2～4 nickel molybdenums is scanned and obtained nickel molybdenum concntrate and mine tailing; During described nickel molybdenum is roughly selected, raw ore per ton adds 0～150 gram of carbonaceous thing inhibitors 4,60～240 grams of collecting agent penta xanthate, 10～30 grams of kerosene, 30～60 grams of foaming agent MIBC.During described nickel molybdenum is selected, each selected 5～80 grams/ton, carbonaceous thing inhibitor that adds; During described nickel molybdenum is scanned, scan at every turn and add respectively 20～70 grams/ton of penta xanthate, 10～25 grams/ton of kerosene.
High charcoal molybdenum nickel minerals flotation molybdenum nickel of the present invention adopts acid orange+ethyl tert-butyl ether (ETBE)+CMC as composite restrainer with carbonaceous thing inhibitor, makes high charcoal molybdenum nickel minerals flotation molybdenum nickel not need to take off in advance charcoal, directly most carbonaceous thing is suppressed in flotation tailing.Use the method for floating of above-mentioned high charcoal molybdenum nickel minerals flotation molybdenum nickel carbonaceous thing inhibitor, can reach 1%～15% to carbon content, the widely different low-grade high charcoal molybdenum nickel minerals of floatability of carbonaceous thing carries out ore dressing, provides molybdenum, nickel grade to exceed 3% molybdenum, nickel ore concentrate for smelting.
Compared with prior art, it is high that new inhibitor of the present invention and method for floating thereof sort efficiency, can effectively suppress carbonaceous thing, makes carbonaceous thing not affect the flotation of molybdenum nickel mineral, significantly reduces molybdenum nickel floating agent dosage, improved the grade of concentrate simultaneously.Adopt new inhibitor of the present invention, make the flotation of high charcoal molybdenum nickel minerals without de-charcoal, technological process is simpler, is easy to industrial implementation and large-scale promotion.
