Description
Technical field
The present invention relates to a kind of high sulphur coal sulfiding volatilization nickel tin iron alloy waste material and oxidative slagging Rhometal and the method reclaiming tin, belong to secondary resource field of comprehensive utilization.
Background technology
China's nickel supply is made up of two parts, and a part newly produces nickel ore concentrate supply, and this part accounts for 72.9% of nickel aggregate supply, and another part accounts for 27.1% from regeneration nickel, and along with the development of economic construction and Iron And Steel Industry, the demand of nickel constantly increases.Within 2010, estimate that Chinese nickel consumption reaches after 400,000 tons/year, China becomes nickel country of consumption the biggest in the world.Within 2010, Chinese nickel metal foundation reserves only have about 2,300,000 tons, and the exploration of 2010-2013 Chinese nickel minerals does not have major progress, if just gone down according to consumption like this, after 10 years, the nickel ore resource of China is by approach exhaustion gradually.Tin resource situation is similar with it, China's tin resource is based on lode tin, the higher-grade resource that the placer tin resource accounting for 88% is easily adopted after exploitation for many years, easily select disappears substantially, and the remaining difficulty that grade is low, silt content reaches that mostly is utilizes placer tin, and retained reserve accounts for 12% of tin resource.The lode tin resource of China can be little for the dew person of adopting, the overwhelming majority bury compared with dark, exploitation difficulty is large, wherein majority is again many metals mineral intergrowth, and selecting and smelting technology difficulty is large.Alleviate the resource pressure of China's copper, nickel resources, the utilising efficiency to secondary resource need be strengthened.
Nickel tin iron alloy waste material is increasing year by year simultaneously, the alloy components damaged in the waste material produced in the waste material produced when mainly comprising mechanical workout, smelting process, industrial sector and part etc.In addition, the nickel tin iron alloy waste material major part that domestic market circulates is bought on ground from Taiwan of Japan, Korea S and China etc., it is the waste material of electronic component factory output, its chemical composition, based on nickel, tin, iron, strengthens there is comparatively positive effect to alleviation China nickel, tin resource pressure undoubtedly to this recycling.But the Land use systems at present about this alloyed scrap is add as alloying element additive in the rear alloy manufacture craft of classification, and utilization ratio is on the low side and economy performance is poor.
At present, the method for material detin mainly contains two kinds:
The first, chloride volatility process, its basic ideas are evaporated with the whole fuming of its muriatic form by the object element in material, then carries out step-by-step processing to flue dust, reaches the object of solid materials separation and valuable metal enriching and recovering.
The second, sulfiding volatilization method, its basic ideas are in material, add vulcanizing agent richness fuel and air mixture burning blowing, make object element form corresponding sulfide and the process of volatilizing.General vulcanizing agent pyrite (FeS
2), it is weakly reducing atmosphere that fuel combustion keeps in stove, blows, to accelerate chemical reaction and volatilization under high temperature and intense agitation.
The present invention makes full use of the high feature of high sulphur coal sulphur content, and for its current utility value situation on the low side, carry out high sulphur coal sulfiding volatilization detin under adopting high temperature weakly reducing atmosphere, oxidative slagging removal of impurities processes nickel tin iron alloy, tin component in material is converted into SnS, SnO and volatilizes system, and it is reclaimed.Effectively reduce nickel tin iron alloy Theil indices on the one hand and realize the recovery to it, nickel tin iron alloy waste material recycling being made qualified ferronickel simultaneously.Therefore, this project implementation is significant to the high-efficiency comprehensive utilization of nickel tin iron alloy waste material.
Summary of the invention

2etc. carrying out molten bath slag making removal of impurities.After held for some time has reacted, the qualified Rhometal of product and slag are discharged by iron notch and cinder notch respectively.
Concrete technology parameter in the above-mentioned processing step of the present invention is:
(1) slag former used is CaO, MgO, CaCO
3, SiO
2deng wherein one or more;
(2), in reaction process, the add-on of slag former is with basicity:
Represent, basicity span of control is 1.2 ~ 1.4;
(1) sulphur content of vulcanizing agent high sulphur coal used is more than 3%, and add-on is with the amount of C/Sn (2,3) thing than representing, scope is 1.3 ~ 1.7;
(2) jetting pressure of high sulphur coal is 0.6-1.3MPa;
(3) melting curing time is 1-1.5 hour;
(4) described rare gas element is nitrogen, argon gas;
Pollution in further minimizing flue gas, reply high-temperature flue gas carries out gathering dust and carrying out washing treatment, enters air after reaching emptying requirement.
The beneficial effect that the present invention has:
1, the feature that this process makes full use high-sulfur sulfur content of coal is high, achieves the treatment of wastes with processes of wastes against one another;
2, technique suitability is comparatively extensive, and technology can extend to the recovery of tin in other stanniferous materials indirectly thus;
3, in material, tin obtains, on the basis of fully recovery, remaining ingredient being made qualified ferronickel, adequately achieving the comprehensive utilization of tin, nickel, iron resources;
4, technological process is simple to operate, and stove maintenance cost is low, and production cost is lower.
