The smelting and refining of some metals can have special hazards. Examples include nickel carbonyl in nickel refining, fluorides in aluminium smelting, arsenic in copper and lead smelting and refining, and mercury and cyanide exposures during gold refining. These processes require their own special precautions. Other hazards
Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel production.
Controlled levels of nickel, iron, and coal in the calcine ensure efficient production of ferronickel with a constant composition during smelting. Ninety percent of smelted ferronickel is used in making stainless steel and other ferrous alloys. The balance is smelted to sulphide matte for refining to nickel metal and other nickel products.
Our refining process involves four key steps: Evaluation Evaluation is a critical stage. During this step we determine the pgm content of the material and agree with the customer on the pgm quantity or value we will return to them. At this stage we provide the lead time for refining.

The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.
Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound ores. Several methods exist for the separation of cobalt from copper and nickel.They depend on the concentration of cobalt and the exact composition of the used ore

Nickel Smelting and Refining Industry Description and Practices Primary nickel is produced from two very dif-ferent ores, lateritic and sulfidic. Lateritic ores are normally found in tropical climates where weath-ering, with time, extracts and deposits the ore in layers at varying depths below the surface. Lat-
The Indian Smelting and Refining Company Limited (ISR), is a part of CK Birla Group, One of the largest industrial houses in India. In 1932, when facilities for manufacturing were virtually lacking, Birla's bought a non-ferrous Foundry from an Englishman.
Jun 22, 2019 · Nickel smelting is the process that nickel ore goes through to eventually remove impurities and leave just the nickel metal. While the ores can come from different stones and sources, they have two categories: lateritic, or rocks found in tropical climates and which contain nickel; and sulfidic ore, which is mined from underground.
Smelting operations, where the original matte is broken down to yield metallic nickel and copper anodes. Electro-refining operations, where these anodes are dissolved electrolytically to produce pure nickel and copper and an anode slime containing the precious metals. Chemical operations, for the separation and refining of the individual metals.
