A kind of preparation method of copper-nickel sulfide mineral collecting agent, comprise the steps: to take vulcanized sodium in molar ratio: phosphoric acid: nitric acid=2 ~ 3:3 ~ 6:2 ~ 5, put into gas generator, collect produce gas pass into 8 ~ 12 C fatty alcohols are housed autoclave in, the mol ratio of fatty alcohol and gas keeps 1 ~ 3:1.5 ~ 3.5, be 10 ~ 12Mpa at pressure, temperature is react 5 ~ 7h under 350 ~ 400 DEG C of conditions, the liquid mixture obtained, cut between collection 150 ~ 250 DEG C is distilled according under the different normal pressure of carbon number, obtain a kind of thick liquid substance, be the collecting agent of copper-nickel sulfide mineral.Adopt collecting agent of the present invention under the condition needing a small amount of activator, can high efficiente callback copper-nickel sulfide mineral, the overall recovery of copper-nickel sulfide mineral reaches more than 90%.
Description
One, technical field
The present invention relates to the preparing technical field of beneficiation reagent, specifically a kind of preparation method of copper-nickel sulfide mineral collecting agent.
Two, background technology
The flotation of nickel sulfide ore both at home and abroad is at present all generally adopt copper sulphate first to activate, then add xanthate and carry out flotation collecting, the flotation recovery rate of nickel sulfide is between 75 ~ 85%, particularly for containing magnetic iron ore high copper, nickel multi-metal sulfide, because the collecting ability of xanthate is not strong, a large amount of copper sulphate must be added activate nickel sulfide mineral, and then carry out collecting.However, still have partial vulcanization nickel mineral to fail to reclaim, cause mineral resources to be lost in mine tailing, so not only beneficiation cost is high, but also affects the economic benefit in ore dressing plant.
Three, summary of the invention
The object of the present invention is to provide a kind of preparation method of copper-nickel sulfide mineral collecting agent, the flotation that it can realize copper nickel sulfide mineral under adding a small amount of oxalic acid to make the condition of activator is reclaimed, not only reduce reagent cost, the rate of recovery of copper nickel sulfide mineral can also be improved simultaneously.
The present invention realizes above-mentioned purpose by the following technical solutions: a kind of preparation method of copper-nickel sulfide mineral collecting agent, comprises the steps:
Take vulcanized sodium in molar ratio: phosphoric acid: nitric acid=2 ~ 3:3 ~ 6:2 ~ 5, put into gas generator, collect produce gas pass into 8 ~ 12 C fatty alcohols are housed autoclave in, the mol ratio of fatty alcohol and gas keeps 1 ~ 3:1.5 ~ 3.5, be 10 ~ 12Mpa at pressure, temperature is react 5 ~ 7h under 350 ~ 400 DEG C of conditions, the liquid mixture obtained, cut between collection 150 ~ 250 DEG C is distilled according under the different normal pressure of carbon number, obtain a kind of thick liquid substance, be the collecting agent of copper-nickel sulfide mineral.
During flotation, ore ore grinding is added sodium carbonate tune slurry pH to 7.5 ~ 8 after mineral monomer dissociates, then add gangue mineral to suppress, then add copper nickel thing activator, finally add described copper nickel thing collecting agent and foaming agent and collecting is carried out to copper nickel thing obtain copper-nickel concentrate.
Described collector dosage: 250 ~ 350g/t
The present invention has the following advantages:
1, described flotation collector is soluble in water, and has good selective and resistance to low temperature.
2, only need a small amount of activator just can carry out collecting to copper nickel thing, reduce reagent cost.
3, owing to being only need a small amount of activator, the recovery therefore for low-grade cu-ni sulphide ore is significant, and the rate of recovery of general copper nickel can reach more than 90%.
