extract the substances from Bauxite, they first grind the ore, then place
it in pressurized tanks where a mass is formed. Continuing the process,
the workers use filters to extract everything except a liquid, which is
treated and in the end yeilds a chemical called alumina. Alumina is a powdery

is removed, producing pure aluminum. Pure Aluminum is very light, it has
luster, which is its shinyness, and it is silver in color. The comon metal
comes in many forms and has many uses. |
