Recovery of valuable metals from copper blast furnace

2004-8-1  Recovery of valuable metals such as copper and nickel from copper blast furnace slag by carbon was studied. The optimum conditions necessary for maximum recovery of these metals with minimum reduction of iron oxide were derived. The effect of several experimental parameters, such as temperature, carbon addition and CaO addition to the slag, on the

Nickel: smelting, producing-Metalpedia

Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.
