Data through upper table show the mineral deposit, aluminium vanadium ferrotianium silicon ore deposit that two mining areas distribute, ore bodies is stored in the diabase, contain multiple beneficial or the harmful elements such as iron, vanadium, titanium, aluminium, silicon, cobalt, calcium, magnesium, manganese, sulphur, phosphorus, scandium in the ore, the ore composite type is complicated, belongs to difficulty and selects the compound mineral intergrowth type of smelting complex aluminium vanadium ferrotianium silicon.
Summary of the invention
In order to separate the mineral resources that Ziyang, shaanxi is pacified ditch-Zhu Xihe, Langao official unit two mining areas, the present invention proposes a kind of method that adopts the gradient magnetic separation process from the compound mineral intergrowth of aluminium vanadium ferrotianium silicon, to isolate ferro-silicon-aluminium and vanadium ferrotianium product.The method is at first pulverized the compound mineral intergrowth of aluminium vanadium ferrotianium silicon, then the compound mineral intergrowth of aluminium vanadium ferrotianium silicon after pulverizing is carried out the high intensity magnetic separation process processing and obtains one-level ferro-silicon-aluminium product and one-level intermediate product; Then adopt method for floating to process and from the one-level intermediate product, isolate sulphide ore and secondary intermediate product, at last the secondary intermediate product is carried out the weak magnetic separation process processing and obtain secondary ferro-silicon-aluminium product and vanadium ferrotianium product.The present invention utilizes by force, the low intensity magnetic separation mode is separated multiple accessory products and reduced manufacture craft, saved production cost, reduced the consumption of electric energy from raw ore.
Can be as the raw material of smelting aluminium, Antaciron through one-level ferro-silicon-aluminium product and secondary ferro-silicon-aluminium product that the inventive method obtains.
Can be as the raw material of smelting titanium, vanadium iron metallic compound through the vanadium ferrotianium product that the inventive method obtains.
Can be as the raw material of smelting cobalt, nickel metal and sulphur product through the sulphur concentrate product that the inventive method obtains.
The present invention is a kind of method that adopts the gradient magnetic separation process to isolate ferro-silicon-aluminium and vanadium ferrotianium product from the compound mineral intergrowth of aluminium vanadium ferrotianium silicon, it is characterized in that including the following step:
Step 1: coarse crushing
Adopting the fragmentation of mechanical disintegration mode to obtain granularity the compound mineral intergrowth of aluminium vanadium ferrotianium silicon is 200 orders～400 purpose coarse crushing ore deposits;
Step 2: fine grinding ore deposit
Adopt grater to pulverize in the coarse crushing ore deposit, obtain granularity less than 200 purpose ore pulps;
The mass percent concentration of described ore pulp is 15～20%;
Step 3: high intensity magnetic separation divides
Dividing electric current with ore pulp at high intensity magnetic separation is that 8A～10A, magnetic field intensity are under 1.1T～1.3T condition, isolates one-level ferro-silicon-aluminium and one-level intermediate product;
Step 4: floating sulphur separate sulfur concentrate
(A) add entry in the one-level intermediate product, it is 25～30% one-level intermediate product ore pulp that configuration obtains mass percent concentration;
(B) in one-level intermediate product ore pulp, add after adjusting agent, collecting agent and foaming agent mix, obtain the one-level intermediate blend;
Add the adjusting agent of 150～200g, the collecting agent of 400～600g, the foaming agent of 140～180g in the one-level intermediate product of consumption: 1000Kg;
Adjusting agent can be sodium carbonate, sodium acid carbonate, NaOH, ammoniacal liquor, lime;
Collecting agent can be butyl xanthate, its xanthate of second, amido black medicine, butyl ammonium aerofloat, cresols black powder, lead ethyl xanthate nitrile ester;
Foaming agent can be terpenic oil, high alcohol oil, fusel oil, methyl anyl alcohol;
(C) the one-level intermediate blend was carried out flotation 5 minutes～10 minutes after, obtain sulphur concentrate and secondary intermediate product;
Step 5: low intensity magnetic separation divides
(A) add entry in the secondary intermediate product, it is 10～15% secondary intermediate product ore pulp that configuration obtains mass percent concentration;
(B) dividing electric current with secondary intermediate product ore pulp in low intensity magnetic separation is that 0.03A～0.05A, magnetic field intensity are under 0.09T～0.10T condition, isolates secondary ferro-silicon-aluminium and vanadium ferrotianium.
The present invention adopts the advantage of gradient magnetic separation process and the auxiliary separation method of sulfide flotation to be:
1. select one-level ferro-silicon-aluminium and secondary ferro-silicon-aluminium with the gradient magnetic method, at first realized the effective separation of vanadium ferrotianium and aluminium silicon.Wherein, the productive rate of one-level ferro-silicon-aluminium is 53～62%, and the sulphur concentrate yield is 1.9～2.4%, and the productive rate of vanadium ferrotianium is 19～25%, and the productive rate of secondary ferro-silicon-aluminium is 14～22%.
2. gradient magnetic separation, first strong after a little less than, can reclaim to greatest extent vanadium ferrotianium metal.
3. from high intensity magnetic separation is rough, select the sulphur concentrate with method for floating, reclaim sulphur, cobalt and the nickel of association in the ore deposit, realize comprehensive utilization of resources.
4. the flow process of industrialized producing technology of the present invention is lacked, is discharged without solid waste, realizes having saved on the other hand production cost under the prerequisite of cleaner production on the one hand, has reduced the consumption of electric energy.
