Description
Technical field
The present invention relates to a kind of antimony oxide ore flotation separation method, particularly relate to a kind of low-grade antimony oxide ore flotation separation method.
Background technology
Antimony is a kind of important strategic resource, be widely used in fields such as printing, battery, alloy, military project, obtaining of antimony metal mainly comes from the antimony sulfide ore that is easy to sort all the time, but along with the further dilution of antimony trisulfide resource and the continuous expansion of antimony metal demand, the antimony oxide resource that is difficult to sort is paid attention to by people gradually.
Sorting of antimony oxide is the difficult problem of ore dressing circle, since fine size, easy argillization, and gravity separation method commonly used can only reach the rate of recovery about 20%.The antimony oxide surface wettability is strong, hydrophily is strong, conventional collecting agent is difficult to make the hydrophobic come-up of antimony oxide, and it is close with gangue mineral character, though the hydrophobic come-up of antimony oxide ore energy, but poor with the gangue mineral sorting, cause the concentrate yield height, concentration ratio is low, is difficult to obtain good economic benefit, does not still have report antimony oxide to be had the floatation process and the flotation collector of efficient sorting both at home and abroad so far.
In order effectively to solve the problem that the antimony oxide ore dressing is recycled, the invention provides a kind of low-grade antimony oxide ore flotation separation method.
Summary of the invention
It is good that technical problem to be solved by this invention provides a kind of flotation efficiency, the low-grade antimony oxide ore flotation separation method that the collecting ability of collecting agent and selectivity are good.
In order to solve the problems of the technologies described above, originally the low-grade antimony oxide ore flotation separation method that provides, at containing Sb is quartz-calcite type antimony oxide ore of 0.5%～2.0% in mass, ore grinding cause a fineness for-it is 70%～90% in mass that 0.074mm accounts for, it is 20%～30% in mass that pulp density is regulated, in ore pulp, add sodium carbonate and the waterglass combined modifier of 2500g/t～4000g/t, the sodium carbonate in described sodium carbonate and the waterglass combined modifier and the mass ratio of waterglass are 4～10:1, the copper sulphate or the plumbi nitras that add 300g/t～500g/t in ore pulp are the activator of antimony oxide, in ore pulp, add 800g/t～1200g/t by carboxyl, the combined capturing and collecting agent that oxygen oximido and sulfonic group are formed, described combined capturing and collecting agent carboxyl in mass: oxygen oximido: sulfonic group=8～9:0.5～1:0.5～1, the FLOTATION SEPARATION of realization antimony oxide and gangue mineral.
Adopt the low-grade antimony oxide ore flotation separation method of technique scheme, in ore pulp, add sodium carbonate and waterglass combined modifier, realize the dispersion of ore pulp and the inhibition of gangue mineral.Add CuSO
