Electrolytic Refining - Mineral Processing & Metallurgy
The commercial production of electrolytic metals had its origin a century ago when James Elkington, an English electroplater, invented a process for refining copper electrolytically; later, about 1890, aluminum was first produced on a commercial scale by electrolysis, followed by lead in 1905, nickel in 1910, and zinc about 1915..
Basic Refinery Process: Description and History Petroleum refining has evolved continuously in response to changing consumer demand for better and different products The original requirement was to produce kerosene as a cheaper and better source of light than whale oil The development of the internal combustion engine led to the ,..
Alumina Refining Quick Read Alumina is the common name given to aluminum oxide (Al 2 O 3) Alumina is produced from bauxite, an ore that is mined from topsoil in various tropical and subtropical regions The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite To produce pure aluminum, ,..
