Lead refining

Process Description The aim of lead refining is to produce sellable lead metal This is done in a refining kettle by separating out unwanted accompanying elements and alloying After copper has been separated out, arsenic, tin and antimony are removed from the lead melt The resulting dross is recycled...

Antimony process

The process for treating antimonial lead which comprises softening the lead, reducing and smelting the antimony slag therefrom to metal, removing tin and arsenic from said metal, concentrating same into a high antimony product and euitectic metal, treating the high antimony product in a fuming furnace thereby yielding antimony oxide, an ....

Lead processing

Lead processing - Lead processing - Refining: To remove and recover remaining impurities from lead bullion, either pyrometallurgical or electrolytic refining is used; the choice between the two methods is dictated by the amount of bismuth that must be eliminated from the bullion and by the availability and cost of energy The Parkes zinc-desilvering process is the most widely used ....

Antimony Smelting

The history of the antimony industry of China dates back to 1897 when the Tai Shing Co was formed, under contract with the Hunan Bureau of Mines, for the smelting of the ore to crude; and in 1908 the Wah Chang Mining & Smelting Co was formed for the smelting and refining of the ore and crude to regulus...

CatCracking | » Antimony passivation of E

Issue When should we consider the use of Antimony for Nickel passivation? Background Please see comment below from latest service report The antimony chemical remains off The E- nickel level has stabilized and even come down some (955 ppm on 8/19/09 vs 858 ppm on 8/28/09) The E- vanadium level has also come down a little (1534 ppm on 8/19/09 vs 1488 ppm on 8/28/09) Question Do you ....

Lead smelting

This process also keeps the lead from oxidizing The molten lead flows from the blast furnace into holding pots Lead may be mixed with alloys, including antimony, tin, arsenic, copper and nickel It is then cast into ingots Lead exposure Humans have been smelting lead for thousands of years, poisoning themselves in the process...
