Abstract
An oxygen sulfur symbiosis zinc mine flotation method uses sodium hexametaphosphate as a dispersant, sodium sulfide as an activator, octadecyl acetic acid amine and kerosene as collectors and No.2 oil as foaming agent. During the flotation, ores are grinded into mineral monomers for dissociation. Then, the sodium hexametaphosphate is added in a stirring barrel firstly, the sodium sulfide is added for activation and octadecyl acetic acid amine, the kerosene and the No.2 oil are added for collection. With the present invention adopted, the flotation and the recovery of oxide zinc and sulfide zinc can be realized at the same time. The process is shortened. The equipment investment is saved and the production cost is lowered. The total recovery rate of the zinc can reach to 85-90 percentages, and the zinc concentrate grade can reach to 39-52 percentages.
Description
One, technical field
The present invention relates to a kind of method for floating of mineral floating method, particularly a kind of oxygen-sulfur paragenesis zinc mine.
Two, background technology
The flotation of zinc sulphide both at home and abroad at present generally all is to adopt copper sulphate activation earlier, adds xanthate then and carries out flotation, and the flotation recovery rate of zinc sulphide is between 85%-90%.But the flotation of zinc oxide is different from zinc sulphide fully, because zinc oxide surface is not easy sulfuration, therefore adopt conventional sulfuration xanthate method to be difficult to realize the flotation of zinc oxide, though adopt the sulfuration that the sulfuration method of heating can the accelerated oxidation zinc surface, but this technology is the index instability in practice, does not obtain extensive use.The fifties in last century, Frenchman Ray invented ammonium sulfide method flotation zinc oxide, and this method is by adding a large amount of vulcanized sodium (7-10kg/t), adding the primary amine collecting agent then and carry out flotation.The flotation recovery rate of ammonium sulfide method flotation zinc oxide is between 50-70%.Because this technology can effectively realize the flotation of zinc oxide and reclaim, and in industrial easy operation, index is stable, it substantially all is at present that the flotation of adopting this technology to carry out zinc oxide is reclaimed that zinc oxide flotation is all over the world produced.
At present both at home and abroad the processing in zinc sulphide mixings ore deposit that partial oxidation is arranged is mainly adopted earlier and reclaimed zinc sulphide, adopt ammonium sulfide method recovery zinc oxide again with copper sulphate xanthate method.For raw ore zinc grade 2-3%, the ore of oxygenation efficiency between 10-30%, adopt substep to reclaim the method for zinc sulphide and zinc oxide, because amount of sodium sulfide is bigger, the zinc oxide flotation recovery rate is low, and production cost is too high, therefore, many enterprises generally all only reclaim the zinc sulphide part for this ore, and do not reclaim zinc oxide, and this has just inevitably caused the wasting of resources.
Three, summary of the invention
The object of the present invention is to provide a kind of flotation recovery that can realize zinc oxide and zinc sulphide simultaneously, can shorten flow process again, save equipment investment, the method for floating of the oxygen-sulfur paragenesis zinc mine that reduces production costs.
The present invention realizes above-mentioned purpose by the following technical solutions: for the zinc sulphide mixing ore deposit that partial oxidation is arranged, employing ammonium sulfide method realizes the flotation recovery of zinc oxide and zinc sulphide simultaneously,
(1) be dispersant with the calgon, vulcanized sodium is made activator, and octadecyl Ammoniom-Acetate and kerosene are made collecting agent, and No. 2 oil is made foaming agent,
(2) slurry pH is 9-10.5 during flotation,
(3) in the floatation process, after ore ore grinding to mineral monomer dissociated, at first add calgon to agitator, add and add the octadecyl Ammoniom-Acetate after the vulcanized sodium activation and kerosene, No. 2 oil carry out collecting,
(4) dosing (g/t) is:
Calgon roughly selects 100～200 selected 20～50
Vulcanized sodium roughly selects 3000～10000 selected 1000～4000
The octadecyl Ammoniom-Acetate roughly selects 250～300 selected 0～50
Kerosene roughly selects 60～80 selected 10～40
No. 2 oil roughly selects 40～80 selected 10～40
The present invention compared with prior art has the following advantages:
1, can reclaim zinc sulphide and zinc oxide simultaneously without stepped-flotation separation, thereby simplify flow process, save equipment investment, reduce production cost.
2, do not need to add the flotation that copper sulphate carries out zinc sulphide, saved the cost of activator, solved because amount of sodium sulfide causes the high problem of cost greatly.
3, in flotation zinc sulphide, reclaim zinc oxide, helped improving the comprehensive utilization of resources rate.The overall recovery of zinc can reach 85～90%.
