How is Iron Extracted from Iron Ore | Actforlibraries
The calcium oxide (CaO) produced by this reaction reacts with other oxides present in the rock, and the reaction products from this run down to the furnace bottom, forming a molten layer on top of the liquid iron known as slag. This is tapped off and used in making cement and roads.
Mining and Refining Aluminum | HowSfWorks
But today, the material is predominantly mined in Australia, Africa, South America and the Caribbean. The first step in the commercial production of aluminum is the separation of aluminum oxide from the iron oxide in bauxite. This is accomplished using a technique developed by Karl Joseph Bayer, an Austrian chemist, in 1888.
