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.
compared to tin mining the history of zinc mining is relatively short. in the 18th century it was discovered that sphalerite or zinc sulfide could be smelted into brass resulting in the first patented techniques. since then the zinc industry has progressed to the current zinc mining process and production methods used today.
manganese (mn) is a hard gray metal that is frequently used in the production of steel. workers may be harmed from exposure to manganese through the breathing of manganese fumes or dusts. continued exposure can damage the lungs liver and kidneys. exposure to manganese dust or fumes can also lead to a neurological condition called manganism.

mar 08 2016018332a water softener is typically used to treat hard water but it can also remove small amounts of reduced iron and manganese. water softeners use an ion exchange process during which the iron and manganese are replaced with sodium. these metals are then removed from the softener filtering resin through a backwashing process.
different data mining methods there are many methods used for data mining but the crucial step is to select the appropriate method from them according to the business or the problem statement. these data mining methods help in predicting the future and then making decisions accordingly. these also help in analyzing market trend and in
manganese is a critical mineral in america and the development of new methods of beneficiation is highly desirable for our national defenses. while much investigational work has been carried out by the u.s. bureau of mines and others there is still a need for more efficient reagents to make many ores economically amenable to the flotation process.
manganese ore beneficiation method the types of manganese ore can be basically divided into manganese oxide ore manganese carbonate ore polymetallic manganese ore etc. therefore manganese dressing equipment is also diverse. manganese ore is generally sorted by gravity separation beneficiation method.
