Zinc smelting Wikipedia

2020. 8. 28.· Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific

Investigation of silver extraction from a silver-sulphur

Abstract. A silver-sulphur flotation concentrate produced from the hot acid leach residue in the electrolytic zinc plant of Companhia Paraibuna de Metais was investigated for hydro-metallurgical silver extraction. This concentrate assayed 8320 g/t Ag, 20.6% Pb, and 43.7% S.

US3923617A Electrolytic recovery of zinc Google Patents

Iron-bearing zinc sulfide concentrates are leached with a sulfuric acid solution containing hexavalent chromium ions, e.g. chromic acid or a dichromate. The leach solution after separation from undissolved residue is hydrolyzed by heating under pressure at a temperature near or above the boiling point of the solution (ordinarily a range of from about 90* C. to about 250* C.) to precipitate

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

Notes on Use of Sulphites in Copper Flotation at the

Description. Soon after the Rosebery concentrator commenced operations in 1936, an investigation was begun in an attempt to discover a substitute for cyanide in lead flotation. Cyanide is an excellent depressant for zinc and iron, but it also powerfully depresses the copper, silver and gold bearing minerals present in Rosebery ore, thus allowing them to pass through to the zinc concentrate or
