Bauxite
Drilling and sampling of bauxite deposits As bauxite deposits are usually extensive, relatively thin (most average <10m thick) and close to the surface, drilling is usually a series of shallow vertical holes set out on a regular grid. It would be rare for drill holes to exceed 50m depth with drilling at most deposits being

Bauxite: Formula, Types & Uses
What is Bauxite? [Click Here for Sample Questions] Bauxite is primarily a metallic mineral, which is the only ore used for large-scale aluminium production. It is a sedimentary rock which contains relatively high levels of aluminium.. Bauxite is the main source of aluminium and gallium.; It appears dull in lustre and is reddish-brown, white, or tan in colour.
