Comparative Analysis of Pyrometallurgy, Hydrometallurgy …

Among the various methods available, pyrometallurgy, hydrometallurgy, and bio-hydro-metallurgy stand as distinct and widely used approaches. The pyrometallurgy process is also called the dry method, the hydrometallurgy process is called the wet method, and the bio-hydro-metallurgy process is called the bioleaching process.

Metallurgy

This process is called Baeyer's process. Roasting: The process of heating a concentrated ore strongly in the presence of excess oxygen at a temperature below the melting point of the metal is called roasting. This process is commonly used for sulfide ores. 2ZnS + 3O₂ → 2ZnO + 2SO₂. During Roasting: Sulphides are partially converted to oxides

State of the art in copper hydrometallurgic processes control

For example, in Chile, the total SX/EW copper produced reached 1400 thousand tons during 1999, representing almost one half of the total electrolytic copper produced (Pezoa, 1999). This paper is focused on the control practices and trends in LX–SX–EW copper plants. Typically, the process starts with the crushing and grinding of ore.
