The impact of the Imperial Smelting Furnace on non-ferrous metallurgy S. W. K. MORGAN N 1936 at the Avonmouth Works of the National I Smelting Company in England, zinc was produced by both the Horizontal Process and by the Vertical Retort Process, then recently installed under licence from the New Jersey Zinc Company. ISF slag contains 610% zinc, so zinc recovery through this process is lower than that achieved by the RLE process. The need to use metallurgical coke is a disadvantage. The major advantage of the Imperial Smelting Process (ISP) is its ability to take a wide variety of feed unsuited to RLE.

Self-heating smelting of sulfide concentrate sustains high-temperature smelting process mainly from the oxidation of sulfide in the concentrate and the heat from ferrous oxide in slag. As it is not necessary to add fuel, it is called heat smelting. Which metals can be extracted by smelting?

33 Chapter 2 Extraction of Non-Ferrous Metals Fig. 2.12 Imperial Smelting Blast Furnace Principle The process is carried out by using counter current principle, where the blast and preheated air given to the furnace through the tuyere and the preheated coke get charged from the top. ISP furnace is of square cross section consists of water jacket brick lined shaft. The zinc blast furnace process is one of the newest pyrometallurgical processes developed by Imperial Smelting Processing Limited in England. In the ISP, ZnO is reduced by carbon to produce zinc. In the reduction carried out by an ISP blast furnace, the zinc that is evolved in the form of a vapor is condensed by using molten lead.

Sep 08, 2020 Zinc smelting is the process of converting zinc ores 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. There are two methods of smelting zinc the pyrometallurgical process and the electrolysis process both methods are still used ...
