antimony smelting process

The metallurgy of antimony - ScienceDirect

Antimony compounds, primarily sodium antimonate, are also used in decolorizing and refining agents for optical glass and CRT glass. In the electronics industry, Sb use grows for diodes. Antimony metal is also used for production of antimonial lead, which is an important product of the secondary lead smelter.

Lead processing - Refining | Britannica

The Parkes zinc-desilvering process is the most widely used pyrometallurgical method of refining lead bullion. As in smelting, the lead is first melted and again allowed to cool below the freezing point of copper, which crystallizes and, along with any remaining nickel, cobalt, and zinc, is removed by skimming. The lead mix then passes to a

Gold Smelting & Refining Process

When the smelting process is complete, the charge is poured into a mold. Once the slag is cool, this can be separate from lead and precious metals by using a hammer or any device than can break the slag. The metallic product is named button and have to be processed in the other smelting process called cupellation.

12.3 Primary Copper Smelting

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. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace.
