The lead in this ore, typically after being concentrated at or ... of precious metals by Parke's Process, in which zinc combines with gold and silver to form an
Smelting is the general term for getting a metal from its natural ore.Gold is an exception, because it is usually found as a pure metal. Other metals, like iron, copper, zinc, and silver, need to be got from their ore.. The process of smelting always involves heating the ore, and may also use a reducing agent like coke or charcoal.Most ores are oxides, sulfides or carbonates.
One process developed in Canada, and capable of recovering 99% of the zinc in the ore, uses pressures in excess of 10 atmospheres and a temperature of ca 420 K. The presence of iron in the ore concentrate is important in this method, as it is in part responsible for the conversion of zinc sulfide to zinc sulfate.
A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead.
Extraction Of Zinc | Extraction of zinc from zinc blende | Electrolysis process. ... The next step is the process of roasting the ores of zinc. The concentrated ore is then treated at 9000 o c in the presence of excess air, on the base of a reverberatory furnace. This process of heating is called roasting. ... Process Of Smelting:

The earliest known process for smelting lead sulphide ore involved oxidizing the ore on an open grate. The principal reactions taking place in such a smelting operation are as follows: PbS Pb S0 2PbS 30 2PbO 280 The metallic lead so formed in accordance with Equation I was collected for subsequent refining while the lead oxide slag was ...
Zinc processing: Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre.
The Imperial Smelting process is based on the reduction of zinc and lead into metal with carbon in a specially designed Imperial Smelting furnace. The IS process is an energy-intensive process and thus became very expensive following the rise of energy prices.
