    zinc: smelting, producing and classification-metalpedia

    Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method.There are two methods of smelting zinc: the pyrometallurgical process and the hydrometallurgical process (over 90% of hydrometallurgical process is in

    Electrolysis is performed in lead-lined concrete cells with anodes of lead containing 0.5–1.0 percent silver and cathodes of aluminum sheet. The zinc deposits are stripped from the cathodes every 24 to 48 hours and remelted in an induction furnace before casting into ingots or pigs. The purification of the electrolyte ensures that the normal product will reach a purity of 99.99 percent or more

    a novel technology for separating copper, lead and zinc in

    The calcine was subjected to sulfuric acid leaching for separation of copper, lead, and zinc; i.e., copper and zinc were leached, and lead was retained in the residue. The optimum parameters of the leaching process were: a leaching temperature of 55 °C; sulfuric acid added at 828 kg/t calcine; a liquid:solid ratio of 3:1; and a leaching time of 1.5 h

    The “green,” or unroasted, charge is first oxidized in a molten bath by the submerged oxygen injection; this produces a flue gas carrying oxides of lead and zinc as well as a slag containing 80 percent of the zinc from the charge. Reduction of the metal oxides occurs when they contact carbon monoxide produced by the natural-gas injection

    zinc pressure leaching (zpl)-zinc- - metalcess

    Zinc pressure leaching (ZPL) treats zinc concentrate directly in the autoclave where specific temperature and oxygen partial pressure is given to leach zinc and generates zinc sulfate solution while sulfur, lead and iron remain in the residue (leaching residue). The leaching residue is further treated with flotation and hot filtration to separate sulfur, lead sulfide residue and tailings
