Description
Technical field
The present invention relates to melting and/or ore dressing tailings resource utilization recovery technology field, especially a kind of non-ferrous metals
Melting and/or ore dressing tailings resource utilization recyclable device and method.
Background technique
China YouSe metallic mineral resources are abundant, are maximum nonferrous production state and country of consumption in the world, copper, lead,
Zinc, tin Isoquant occupy first, the whole world, and a large amount of solid waste can be generated during production and processing, and such as lead zinc is molten
Refine the coloured solid wastes such as slag, copper weld pool slag, tin smelting slag.
Lead smelting or ore dressing tailings are that lead concentrate or lead-acid accumulator etc. give up containing what scrap lead generated after high melt
Waste, one ton of lead of every production, the smelting slag of 0.7-0.8 ton of general output are produced 5000000 tons of lead per year by China and are calculated, annual to generate
Up to more than 300 ten thousand tons of castaway slags.One ton of copper of every production is by 2 tons or so of generation of smelting slag, not with China's Copper making scale
It is disconnected to expand, 16,000,000 tons or more of melting waste slag will be generated every year, and accumulative accumulation storage capacity is more than hundred million tons at present.Tin selects smelting process
In can generate a large amount of stanniferous, iron waste residue, mainly reverberatory smelting slag, electro-smelting slag, fuming furnace Water Quenching Slag, ore dressing tailings
Deng annual yield millions of tons.This kind of melting ore dressing tailings complicated component, except valuable containing a small amount of lead, antimony, tin, zinc etc.
It is with higher additional also containing a large amount of iron, silica, calcium oxide and partial oxidation magnesium, aluminum oxide etc. outside metal
Value.In smelting slag, lead content 0.5-5%, antimony content 0.5-2.5%, Theil indices 0.2-2%, iron is mainly with magnetic iron ore, troilite, silicon
The forms such as sour iron exist, and the grade of iron is 20-50%.Far more than 20% mining grade of iron ore.
China's smelting slag comprehensive reutilization technology and not perfect at this stage usually air storage or is sold to cement at a low price
Factory never realizes resource utilization valuable metal therein.A large amount of long-term accumulations of these smelting slags can bring serious
Water body and soil pollution, caused pollution has the characteristics that concealment, chronicity and irreversibility, to the potential of ecological environment
It is very harmful.
Currently, traditionally using ore-dressing technique, iron is separated with magnetic method, with flotation gravity separation method separation lead, iron, copper etc., is led to
Cross magnetic separation to smelting slag, gravity treatment, flotation carry out ore dressing, but the technique is there are long flow path, investment are big, the separation of the metals such as lead, iron
The disadvantages of effect is poor, and wherein the valuable metals such as antimony, tin, zinc can not effectively be recycled, be resulted in waste of resources.Together
When, fine grinding is needed in slag ore-dressing technique and medicament is added, and there are secondary pollution hidden danger for the tailings of output.
With the reduction increasingly of resource, the valuable metals such as iron, lead, antimony, the tin in melting ore dressing tailings are rationally recycled, can be mentioned
The economic benefit of high smelting recovery and enterprise.If not being pocessed and recycling, the wasting of resources is not only resulted in, it can also be to ecology
Environment causes seriously to pollute.Melting ore dressing tailings are handled, the valuable metals such as iron, lead, antimony, tin, zinc are therefrom recycled, it can
Smelting slag is set to obtain abundant resource utilization, to realize the value maximization of melting ore dressing tailings.It can be seen that selecting melting
Valuable metal separation and the research of recovery technology have important economic value and environment protection significance in mine tailings.
Smelting iron and steel, processing, manufacture production process in can generate a large amount of iron content solid waste, in such as ironmaking processes
The iron-containing dust that dust pelletizing system is collected, makes steel the steel slag of generation, the iron scale that when steel forging and hot rolling, hot-working generates,
Cut the gas cutting slag etc. that steel generate.These iron content solid waste amounts that China generates every year are up to ten million ton or more, wherein iron content 20-
90% differs, these iron content solid wastes generally recycle inside steel mill or are sold to small-sized iron-smelter at a low price, but all there is technique and fall
Afterwards, the rate of recovery is low, and the problem of environment difference has been unable to meet the higher and higher environmental requirement of modern production firm.
Summary of the invention
The invention aims to provide a kind of smelting non-ferrous metal and/or ore dressing tailings resource utilization recyclable device and
Method, the existing recovery rate of valuable metals when handling melting ore dressing tailings is low in the prior art, metallic iron recycling is difficult for solution,
The wasting of resources, secondary pollution or the cumbersome problem of process flow.
The object of the present invention is achieved like this: smelting non-ferrous metal and/or ore dressing tailings resource utilization of the invention
Including smelting recovery plant and melting recovery method.
