Description
Technical field
The present invention relates to a kind of beneficiation method that reclaims bismuth from select the molybdenum mine tailing.
Background technology
Bismuth is typical eare scattered metals element.Although the Independent Mineral of bismuth is common, few enrichment is the Independent Industrial mineral deposit.Bismuth mainly is present in the ores such as tungsten tin mine, plumbous zinc ore, copper mine, molybdenum ore and gold mine with accompanying element, and content is lower, comprehensively reclaims usually used as byproduct.Fusing point low (271 ℃) due to bismuth, be used to make fusible alloy very early, is widely used in fire-fighting and electrical equipment industry field.
China's bismuth resource reserve occupies first place in the world, and is maximum in the world bismuth producing country, is again maximum in the world bismuth raw material exported country.Bismuth mineral has kind more than 50, and what industrial value was arranged is bismuthine, basobismutite, bismite and native bismuth etc.The independent bismuth deposit of China is few, and the overwhelming majority all belongs to molybdenum bismuth intergrowth deposit.And the floatability of molybdenum is better than bismuth, therefore normally preferentially selects molybdenum, then reclaim bismuth from select the molybdenum mine tailing.Select the molybdenum mine tailing to carry out the milltailings of self-contained molybdenite, bismuthine, wherein contain Mo and be less than 0.01%, contain Bi 0.25 ~ 15%.Following characteristics appears in the exploitation along with the bismuth mineral resource: 1) difficulty selects the bismuth mineral resource to increase gradually.Bi content is more and more lower, and disseminated grain size is thinner, more complicated with the symbiosis of other mineral; 2) existing technique of preparing falls behind, and the bismuth rate of recovery is low.Bismuth mineral reclaims still take flotation as main, is mainly under alkaline environment, to adopt lime, vulcanized sodium etc. as inhibitor at present, suppresses the sulfide minerals such as pyrite, the flotation bismuthine.Because the good pyrite of part floatability is very difficult suppressed, cause inferior separating effect.Therefore need a kind of ore dressing new method that reclaims bismuth from select the molybdenum mine tailing badly, improve the comprehensive utilization ratio of bismuth resource.
CN201210035477.4 discloses the beneficiation method of low content molybdenum bismuth in a kind of polymetallic ore, in selecting the molybdenum mine tailing, adds lime and makes inhibitor, and diethyldithiocarbamate is made collecting agent and reclaimed bismuth mineral.CN201010157945.6, disclose a kind of beneficiation method of native bismuth mineral, in selecting the molybdenum mine tailing, adds sodium carbonate, lime, waterglass, zinc sulfate and make inhibitor, and butyl xanthate etc. are made collecting agent and reclaimed bismuth mineral.CN201210036062.9, disclose the beneficiation method of low content molybdenum bismuth in a kind of polymetallic ore, by adding sodium carbonate, lime, vulcanized sodium, makes inhibitor in selecting the molybdenum mine tailing, and butylamine black powder and diethyldithiocarbamate reclaim bismuth mineral as collecting agent.Above-mentioned three all adopts the alkaline inhibitor such as lime, sodium carbonate, vulcanized sodium or waterglass, and flotation bismuthine under alkaline environment, be unfavorable for the activation of bismuthine, causes the rate of recovery lower.
CN200910082391.5 discloses a kind of separation method of molybdenum and bismuth sulfide minerals, and the method adopts waterglass to size mixing, and the inhibitor that uses dihydroxy ethyl carbamic acid sodium or dihydroxy ethyl potassium carbamate to separate as the bismuth sulfur mineral.At first, the method is flotation bismuthine under alkaline environment, is unfavorable for the activation of bismuthine, causes the rate of recovery lower; Secondly, the inhibitor that uses with high costs.
Summary of the invention
The object of the invention is to provide a kind of beneficiation method that reclaims bismuth under solutions of weak acidity from select the molybdenum mine tailing, to solve under alkali condition, and the problem that the bismuthine activation is poor, the rate of recovery is low.
The present invention is achieved through the following technical solutions: 1) size mixing: selecting the interpolation concentrated sulfuric acid to slurry pH in the molybdenum mine tailing is 5 ~ 6, stirs 10 ~ 15 minutes; 2) roughing flotation: by the molybdenum mine tailing that selects per ton, calculate, add activator plumbi nitras 200 ~ 500g, collecting agent butyl xanthate 100 ~ 200g and foaming agent terpenic oil 10 ~ 20g do one roughing, obtain roughly selecting concentrate and rougher tailings; 3) flotation is scanned: the rougher tailings once purging selection is added to butyl xanthate 50 ~ 100g and foaming agent terpenic oil 5 ~ 10g, and secondary is scanned interpolation butyl xanthate 50 ~ 100g and foaming agent terpenic oil 5 ~ 10g or blank and is scanned, and obtains scavenger concentrate and flotation tailing; 4) flotation is selected: to do 3 ~ 4 blank selected to roughly selecting concentrate, obtains bismuth concentrate and cleaner tailings; Cleaner tailings and scavenger concentrate are back to the roughing flotation operation.
The method is the flotation bismuthine under acid condition, has greatly improved the floatability of bismuthine, has improved flotation recovery rate, the bismuth rate of recovery>85%, and the bismuth concentrate contains Bi>20%.
Technical scheme of the present invention has following characteristics: 1) adopt sulfuric acid that ore pulp is adjusted to faintly acid, can remove the sludge of bismuthine surface cover cap and residual medicament, clean the bismuthine surface, help the absorption of the medicament of follow-up interpolation on its surface; 2) adopt plumbi nitras to make activator, can improve the floatability of bismuth mineral, increase substantially the flotation recovery rate of bismuth; 3) technological process is simple, and beneficiation cost is low; 4)
Abandon tradition and under alkali condition, adopted the method for the medicament flotation bismuth mineral that cyanide, vulcanized sodium, lime etc. are poisonous, the smell is awful and corrosivity is stronger, adopt new method flotation bismuthine under solutions of weak acidity, environmental protection more, efficient, be applicable to the molybdenum ore of bismuth-containing.
