Refining dross is the result of lead refining process where impurities like copper, tellurium, arsenic-antimony-tin, silver, zinc and bismuth in sequence from lead bullion. There are many types and composition of each type of dross varies and is subjected to specific refining steps and raw material contents. Conversely, lead refining process ...
The blast furnace produces an ordinary grade of zinc containing 1.2 percent lead. This can be used in general galvanizing, but an additional refluxing operation must be performed to produce high-grade zinc. The operation is performed in two fractionating columns, each consisting of a series of superposed rectangular trays made of bonded silicon ...

The molten lead flows to the bottom of the furnace where four layers form: "speiss" (the lightest material, basically arsenic and antimony); "matte" (copper sulphide …
Copper Dross. Generally speaking, the copper dross is treated by rotatory reverberatory furnace. In case of copper dross with high arsenic, tin and antimony, caustic soda plus iron filings are used. In reaction with caustic soda, the arsenic, tin and antimony report to sodium salt as slag to be recovered by hydrometallurgy consequently. After ...
The first stage in the refining of lead blast furnace bullion is the removal of copper and is normally done as a batch process in open kettles.A number of attempts have been made to establish continuous processes operating in reverberatory type furnaces, but the growth of accretions in the furnace has always presented a serious problem.The Broken Hill …
Lead bullion composition depends on the furnace and flux type used. The most common contaminants are antimony, cadmium, arsenic, silver, copper and gold . Single Stage Processing. The historical worldwide standard for lead smelting is the conventional sinter-blast furnace using coke . Blast furnaces produce high antimony …
blast furnace. A zinc-lead blast furnace and lead-splash condenser. Sintered zinc and lead concentrates, mixed with metallurgical coke, are charged into the top of a shaft furnace, into which preheated air is blown …
smelted in a blast furnace to produce rough lead bullion. Rough lead bullion still contains many impurities. Therefore, the rough lead bullion is refined to remove and recover …
Depending on the nature of the concentrate, the bullion exiting the smelting furnace contains a particularly broad range of impurities. For example, smelters of complex …

A. Berankova. This article analyzes the effect of zinc in the blast furnace process and it also analysis its contents in the input and output raw materials. The results obtained in the long-term ...
The furnace burden is reduced in the blast furnace and the lead bullion is discharged by batches. Two refining approaches, i.e. fully fire-refining and fire-refining + electro-refining can be selected based on lead bullion content. ... Blast furnace has been used for iron/copper/copper -nickel/zinc/lead and zinc-lead complex concentrate ...
