Zinc Refining - Metallurgist & Mineral Processing Engineer

Owing to the presence of lead in most zinc ores, the bulk of the spelter produced by direct smelting is of this Prime Western grade. Careful selection of ores of low lead content gave purer grades of spelter, i.e., Brass Special and Intermediate; and smelters which could secure ores carrying practically no lead produced high-grade spelter. Thus, in general, the grade of spelter produced by any ...

:: WorstPolluted.org : Projects Reports

Lead smelting is an industrial process that treats lead ores to remove impurities, and then using furnaces and through the addition of fluxes and other chemical agents produces metallic lead. Primary lead smelting uses mined ores while secondary lead smelting reprocesses use lead scrap material collected through various recovery streams. The primary source of lead ore is from the mineral ...
