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

2021-10-30  Japan Japan Resources and power: With few exceptions, Japan’s mineral reserves are small, and the quality of those mined is often poor. Coal, iron ore, zinc, lead, copper, sulfur, gold, and silver are among the most abundant minerals (in relative terms), with lesser quantities of tungsten, chromite, and manganese. Japan also has large deposits of limestone.

Selective recovery of zinc from mining sulfuric liquor

2021-8-1  The process of obtaining zinc through hydrometallurgical routes consists of leaching the metal from primary or secondary sources [11,12], followed by a precipitation treatment [5,13]. In the solvent extraction stage, the liquor is held in contact with an organic solvent and an extracting agent for the selective recovery of zinc [14,15].
