The chemical processing of ores to recover the metal values in pure form is commonly referred to as extractive metallurgy as presently practiced it is subdivided into hydrometallurgy and pyrometallurgy. Hydrometallurgy involves reacting the ore at low or moderate temperatures with a hquid solvent that will selectively dissolve the valuable metal or metals, separating the dissolved metals from each other by... 

Extractive metallurgy is the general term for the processes such as pyrometallurgy, hydrometallurgy, and electrometallurgy that... 

Pyrometallurgy. Metallurgy involved in winning and refining metals where heat is used, as in roasting and smelting. PyrometaHurgy is the oldest extractive process and is probably the most important. 

Pyrometallurgy, metallurgy at high temperatures, is considered with particular attention to iron. Hydrometallurgy, the extraction of metals using aqueous solutions, is discussed with particular attention to aluminum.
