burden (waste-to-ore) ratio for surface mining of metal ores generally ranges from 2:1 to 8:1, de-pending on local conditions. The ratio for solid wastes from underground mining is typically 0.2:1. Where concentration or other processing of the ore is done on site, the tailings generated also have to be managed. Ores with a low metal con-
Aluminum is made when refining alumina, which is in turn found from the ore 'bauxite'. Bauxite is often mined in the opencast method. Aluminum deposits are found in many countries, but the countries with significant deposits include: Guinea, Jamaica, Surinam, Australia and Russia.
Africa leading the Way with Bauxite Production. Bauxite is an aluminium ore. It is known for being the main source of aluminium in the world. Bauxite was first discovered by a French geologist called Pierre Bertheir in 1821 in Provence in the South of France in Les Baux village.
In 2017, China was the top producer of aluminium with almost half of the world's production, followed by Russia, Canada, and India. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.

Unlike the base metal ores, bauxite does not require complex processing because most of the bauxite mined is of an acceptable grade. Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as "beneficiation", which include washing, wet screening and mechanical or manual sorting.
