Abstract
The invention provides an environment-friendly beneficiation method of antimonyore, which takes H2SO4 as ore pulp pH value conditioning agent and Al2(SO4)3 as antimonyore activator; the flotation effect which is the same as taking lead nitrate as the antimonyore activator can be obtained; the new medicament combination of butyl ammonium aerofloat, diethyldithiocarbamate and No. 25 black powder can be adopted, and the auxiliary agent is saved. The technical method is simple and free from pollution, can improve the surrounding environment of the place where antimonyore enterprises are positioned, and the beneficiation cost is greatly reduced. Antimony concentrate prepared by the beneficiation method has low lead content and high recovery rate, thus being a new way of environment-friendly antimony beneficiation.
Description
Technical field
The present invention relates to ore dressing field, be specifically related to a kind of beneficiation method of antimony ore.
Background technology
Along with the develop rapidly of global economic integration, national economy grows with each passing day to the requirement of non-ferrous metal.Antimony is as the important means of production in industrial production and the people's lives, because antimony alloy has the characteristic of many excellences, thereby it is of many uses, as cable sheathing and war industry etc. at the bottom of accumulator plate, bearing, printing type, family expenses alloy, the pond, antimonial also is widely used in each industrial department.But since in the ore dressing process of antimony in order to improve the floatability of antimony, used plumbi nitras, the use of plumbi nitras has increased content plumbous in the antimony concentrate, also increased the content of lead ion in the tailing water, caused plumbous to the on-site lead contamination of enterprise.Thereby need to seek the substitute of nontoxic medicament as plumbi nitras, and eliminate the on-site lead contamination of enterprise, have important social effect.
Lead is the important impurity of antimony concentrate, and the leaded high meeting of antimony concentrate influence the antimony metal quality, increases the smelting cost of antimony.Plumbi nitras is applied in the ore dressing production of antimony always as the antimony mineral activator of antimony ore ore dressing, and the use of plumbi nitras has increased the lead content of antimony concentrate, has influenced the grade of antimony concentrate.A part of lead evaporate in the air in the smelting of antimony, and a part then remains in the metallurgical slag.In order to reduce the lead content in the antimony metal, also must use deleading agent in smelting process, the use of deleading agent has increased the cost that antimony is smelted.
The antimony metallurgical slag is accumulated in the face of land or buries, because lead enters into surface water with rainwater in the oxidation antimony slag, has influenced the local water quality of antimony ore enterprise, causes local water body lead content to exceed standard, and has had a strong impact on health.2008 age and service seniority river body Anhua, Lengshuijiang section exceed standard, and have caused to have a strong impact on.It is leaded to fall antimony concentrate, seeks the medicament that substitutes poisonous medicine plumbi nitras activation antimony mineral, and very big social benefit and economic benefit are arranged.
Activator is the major terms of ore dressing field, thereby its effect is the interaction raising mineral floatability that promotes and strengthen mineral and collecting agent, and this effect is called activation, and the medicament that can play this effect is called activator.
Medicament with activation mainly is a little common inorganic compounds, comprising: nonferrous heavy metal cation and corresponding solubility salt thereof such as copper sulphate, plumbi nitras, silver nitrate etc.; Alkaline-earth metal ions and corresponding solubility salt such as calcium chloride, barium chloride etc.; Dissolvable sulfide such as vulcanized sodium, NaHS, hydrogen sulfide and calcium sulfide etc.; Inorganic acid, alkali such as sulfuric acid, hydrochloric acid, hydrofluoric acid or sodium carbonate, NaOH etc.So far flotation production practices and theory all prove, manage to seek the activator of various special efficacys, to effective separation of realizing various mineral with promote the development of flotation technology to have great significance.Therefore, to correctly grasp the kind and the consumption of activator, to obtain optimum economic benefit and social benefit at floatation process.Avoid pollution to environment.
Summary of the invention
For overcoming the shortcoming seriously polluted in the existing antimony ore ore dressing process, that dosing is big, cost is high, the invention provides a kind of beneficiation method of antimony ore, adopt pharmaceutical preparations to substitute high pollution, highly toxic plumbi nitras.
Technical scheme of the present invention is: a kind of beneficiation method of antimony ore, this method is: the antimony ore crushing raw ore is arrived smaller or equal to ore grinding behind the 20mm, and being milled to fineness is the 60%-70%-200 order, adjusts the pH value to 6-6.5, adds the Al of 800 gram/tons-1100 gram/ton

3Carry out stir-activating, carry out flotation again,, scan and recleaning for three times, obtain antimony concentrate through one roughing.
Described floatation process adds aerofloat 226, diethyldithiocarbamate and No. 25 black powder combinations as the antimony ore collecting agent; Wherein, the aerofloat 226 consumption is 100 gram/tons-120 gram/tons, and No. 25 black powder consumptions are 50 gram/tons-70 gram/tons, and the diethyldithiocarbamate consumption is 60 gram/tons-90 gram/tons.
In the said process, adjust the H that the pH value adopts 1500 gram/tons-1700 gram/ton

Above-mentioned described antimony ore refers to antimony sulfide ore; Described dosing is meant the weight of the employed medicament of all ores that participation per ton sorts; Describedly roughly select, scan with selected all be conventional technique of preparing.
In the antimony floatation process, because the antimony mineral floatability is relatively poor, in industrial practice, all need add a certain amount of activator activation, activated back adds the collecting agent flotation, for a long time, Pb (NO

2Use till today as the optimal activation agent of antimony mineral always, but, improve the location surrounding environment protection people's of antimony ore enterprise physical and mental health, have and important meaning because lead ion to human health damage, is sought the substitute of plumbi nitras.Technical scheme of the present invention adopts H
2SO
4Adjust agent as slurry pH, slurry pH is transferred to 6-6.5, under acid condition, antimony trisulfide has floatability preferably, and the rate of recovery of antimony trisulfide is than higher in neutrality or alkalescence; Adopt Al then

3As the activator flotation antimony mineral of antimony mineral, be an innovative point in the antimony ore field of sorting, do not adopt Al at present at home and abroad
2(SO

3Choose the report of antimony ore as the antimony ore activator, add Al
2(SO

3After, aluminium ion is adsorbed on the surface of antimony trisulfide mineral, has promoted the collecting effect of collecting agent to antimony mineral, improves the rate of recovery of antimony, reaches the purpose to the antimony mineral activation.Adopted new medicament combination aerofloat 226 after the antimony mineral activation, diethyldithiocarbamate and No. 25 black powder are as collecting agent flotation antimony, and the flotation collecting ability that above-mentioned composition and xanthate class collecting agent compare antimony mineral is stronger, selectivity is better.
Conventional flotation antimony sulfide ore technology must use a large amount of neutral oil such as kerosene, coal tar and diesel oil etc. as antimony flotation assistant, improves the rate of recovery and the concentrate grade of antimony.Flotation antimony need not use assistant in the technical scheme of the present invention, can reach higher antimony recovery and concentrate grade equally, and the use of having saved assistant effectively reduces beneficiation cost.
The present invention adopts H
