How Aluminum is Produced Rock, Mineral and Fossil

The production of the metal Aluminum from the raw ore of Bauxite is a two stage process. Alumina recovery begins by passing the bauxite through screens to sort it by size. It is then crushed to produce relatively uniformly sized material.

Setting Up the Proper Recovery System

If the suspended medium in the recovery system is heavier than your target mineral, the system will then be set up to discharge your target mineral along with tailings. What you should do with the heavy materials from the bottom of a jig depends entirely upon what they contain.

Mineral Recovery From Ore? Yahoo Answers

Apr 15, 2008A more recent tehnique has been develpoped called biochemical leaching, that uses bacterial enzymes to treat the ore. These are very much less hazardous. One problem with these techniques is that large volumes of the resultant solution (the 'pregnant liquor') have to be treated, to recover the metal from solution.
