The manufacturing technique process of the invention comprises furnace charge adding, heating up and melting, deslagging, iron chips adding and replacing, depositing and separating, sulphonium discharging, cooling down and lead obtaining. The furnace charge proportion adopts the proposal that auxiliary materials are required to be prepared for copper dross slag or ingot casting slag per 100 kg: 6 to 10 kg of soda, 2 to 4 kg of pulverized coal, antimony-bearing smoke, and 5 to 50 kg slag. The method has the advantages that the intermediate slag and the smoke produced in the manufacturing process of electrolytic lead and noble metal can be processed effectively, and the valuable metal such as Ag, Sb, Pb, etc. can be recycled effectively. The manufacturing method has the obvious advantages that the production efficiency is high, the labor intensity is low, and the production cost is low.
Description
Technical field:
The invention belongs to plumbous field of metallurgy, particularly relate to a kind of method of producing high-stibium crude lead.
Background technology:
In the electrolytic lead refining process, antimony forms the loose porous reticulated structure of strong yet at anode surface, and the parcel anode sludge makes it to have suitable adhesion strength and do not come off.The anode antimony content is low excessively, and the anode sludge is fragmentary coming off easily, makes the electrolytic solution muddiness, and precious metal is difficult for reclaiming, and separates out plumbous difficult quality guarantee; It is too high that anode contains the antimony amount, can make the anode sludge become hard and be difficult to scrub.Therefore, the total content of antimony in the lead anode and arsenic (Sb+As) is controlled at 0.8～2.0%.And it is lower through the resulting lead bullion antimony content of retailoring under normal conditions, need adjust it and satisfy manufacturing requirements, so many enterprises contain the high lead bullion of antimony or star metal and join in the lead anode to satisfy production requirement when the preliminary fire refining by buying a part, but because star metal market value height can cause electric lead anode production cost height.
In the precious metal leaching process output contain the antimony flue dust because complicated component, science and engineering skill in original place is very loaded down with trivial details, still not have to adopt directly with electric plumbous production process in the part copper scum silica frost of output or the method that the ingot casting slag is together handled the direct production high-stibium crude lead.
Summary of the invention:
Purpose of the present invention is just in order to overcome the weak point that above-mentioned prior art exists, and provide that a kind of technological process is simple, production cost is low, labour intensity is low, can the efficient recovery slag, valuable metals such as Ag, Sb in the flue dust, Pb; Some that utilize output in part copper scum silica frost, ingot casting slag and the precious metal leaching process of output in the electric plumbous production process contain the method for antimony flue dust, slag direct production high-stibium crude lead.
The present invention realizes its goal of the invention by the following technical solutions, and its production process is: add furnace charge-intensification fusing-slagging-Jia iron powder replacement-precipitate and separate-put sulfonium-lead of lowering the temperature-go out; Charge composition is that every 100Kg copper dross slag or ingot casting slag need be joined auxiliary material: contain antimony flue dust, slag 5～50Kg, soda 6～10Kg, fine coal 2～4Kg; Fire box temperature should keep 1100-1200 ℃ of furnace temperature, smelting time 7-10 hour more than 1000 ℃ during the furnace charge charging during the melting process; Stir it furnace charge fusing back, is warmed up to 1200-1300 ℃ of redeposition and begins slagging after half an hour; Put and add iron filings 0～15Kg by every 100Kg copper dross slag or ingot casting slag behind the slag and replace, time swap is 0.8-1 hour, makes its precipitate and separate, again through putting sulfonium, putting the sulfonium time is 0.4-0.8 hour, put reduce behind the sulfonium temperature to 400-600 ℃ can the output high-stibium crude lead, going out the plumbous time is 2-3 hour; The ratio of components of furnace charge the best of the present invention is: every 100Kg copper dross slag or ingot casting slag, and need join auxiliary material and be: contain antimony flue dust, slag 40Kg, soda 10Kg, fine coal 4Kg.Need not add iron filings replaces.
Technical characterstic of the present invention be in copper dross slag, ingot casting slag, allocate suitable proportion into contain materials such as antimony flue dust, slag, utilize converter to realize.
The invention has the beneficial effects as follows: technical solution of the present invention, have characteristics such as technology is simple, level of automation is high, production efficiency is high, labour intensity is low, production cost is low, simultaneously the remarkable advantage of valuable metals such as Ag, the Sb in efficient recovery slag, the flue dust, Pb.
Further set forth content of the present invention below in conjunction with accompanying drawing and example.
