Pyrometallurgy | Metallurgy for Dummies

Pyrometallurgy is a branch of extractive metallurgy. Pyrometallurgy Basic Principle. The basic premise of most pyrometallurgical operations is simple: high-temperature chemistry is employed to segregate valuable metals in one phase while rejecting gangue and impurities in another phase. In most instances, both phases are molten (such as the matte and slag in a conventional copper smelting ...

NICKEL PLATING HANDBOOK

Nickel electroforming is the process by which nickel is built up by electrodeposition onto a suitable mandrel and subsequently removed to produce a nickel product which corresponds precisely to the shape and texture of the original substrate.
