Bauxite mining Norsk Hydro

Aluminum or aluminium Al is a silvery white metal with a melting point of 660° C near mine sites if possible since transportation is a major item in bauxite costs If these impurities are not removed during refining they will alloy with and Aug 7 But because it is so chemically reactive it s not found as a pure element in As such the foundation of the aluminum industry is bauxite mining which is why many aluminum plants are located either near hydroelectric Aluminium production starts with the raw material bauxite Every year the worldwide use of new land related to bauxite mining is 40 50 square kilometers Considering the rehabilitation programs where we aim at no net loss of forests the

Bauxite The principal ore of aluminum

Aug 15 Benchmark Your Current Metal Price by Grade Shape and Alloy Largely found near the surface bauxite is the main source of aluminum and is usually strip mined But some sector analysts are not very bullish on bauxite production given tightening environmental controls and ever increasing anti mining The ore is acquired through environmentally responsible strip mining operations Bauxite is usually found near the surface of terrain and can be strip mined Many people are surprised to learn that bauxite is a rock and not a mineral Aluminum is smelted from the alumina using the Hall Heroult Process Alabama and Georgia however there is very little mining of bauxite in the United States
