Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies.
front end loaders. Bedded barite deposits are more extensive and have more consistent grades; these can be exploited by large-scale open pit methods, followed by relatively simple processing. Barite is extracted by both surface and underground mining, generally followed by simple physical processing methods to produce correctly sized product and to

The Wessels mine is situated in the Northern part of the Kalahari Manganese field. Mineralisation of the Kalahari Manganese field is developed in three braunite-kutnahorite lutite layers interbedded with iron formation in the Hotazel Formation of the Palaeoproterozoic (2400 to 2100 Ma) Transvaal Sequence which was deposited within an intracratonic basin on the Kaapvaal Craton.

Barite is present in a number of zones, known as the Bear, Moose, Beaver and Wolf zones. Formerly the largest, before it was mined, is the Moose zone where a system of barite veins occur within a north-striking, steeply dipping, anastomosing fault zon. Barite pinches and swells along the structure and rarely exceeds 3.5 metres in width.
Barite is extracted by both surface and underground mining and most barite requires upgrading to achieve minimum density or purity levels. Processing methods such as crushing and milling is often followed by wet gravity concentration methods, for example spirals and jigging to remove gangue minerals and produce correctly sized product.
Used as a weighting agent for drilling fluids in oil and gas exploration to suppress high formation pressures and prevent blowouts.
Commercial barite is mined from surface or near-surface deposits by open-pit or underground mining methods. Baryte is used in the manufacture of paints and paper. Baryte that is used as an aggregate in a "heavy" cement is crushed and screened to a uniform size.
