Nickel Smelting and Refining

In this process, copper and precious metals remain as a pyrophoric residue that re-quires separate treatment. Use of electrical cells equipped with inert cathodes is the most com-mon technology for nickel refining. Electro-winning, in which nickel is removed from solution in cells equipped with inert anodes, is the more common refining process.

Antimony roaster project Oman

5 ERG''s customer buys stibnite ore (antimony sulphide) This arrives in containers into Sohar port and is delivered by road to the plant After quality checks and blending, the ore is fed into the Roaster where it is heated and oxidised with air to form antimony oxide vapour. Sulphur dioxide (SO 2) is a byproduct The flue gas from the roaster is then cooled.

Lead processing

Lead processing - Lead processing - The metal and its alloys: Refined lead usually has a purity of 99 to 99.99 percent, but lead of 99.999 percent purity (known as "five nines") is becoming more common commercially. At these levels, the grades of lead differ mostly by their bismuth content. With modern smelting and refining techniques, it is possible to reach these high levels of purity ...

Zone melting

Zone melting (or zone refining or floating-zone process or travelling melting zone) is a group of similar methods of purifying crystals, in which a narrow region of a crystal is melted, and this molten zone is moved along the crystal.The molten region melts impure solid at its forward edge and leaves a wake of purer material solidified behind it as it moves through the ingot.

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.
