In modern ore treatment, various preliminary steps are usually carried out before smelting in order to concentrate the metal ore as much as possible. In the smelting process a metal that is combined with oxygen—for example, iron oxide—is heated to a high temperature, and the oxide is caused to combine with the carbon in the fuel, escaping ...
Before smelting iron, the ore is frequently crushed and grounded to increase its surface area, improving the chemical interaction between the iron ore and the reducing agent. In certain situations, the iron ore is concentrated using procedures like flotation or magnetic separation to eliminate impurities and enhance metal content. …
Nickel processing - Extraction, Refining, Alloying: 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 …
