SOUTH AFRICA'S BENEFICIATION STRATEGY AND THE PROPOSED CHROME ORE EXPORT TAX: THE RELEVANCE TOWARDS ECONOMIC DEVELOPMENT. Mahlangu Morris Mgiyela Selby (Student number: 1053965) Supervisor: RCA Minnitt A research thesis submitted to the Faculty of Engineering and the Built Environment,
The inorganic material that are derived from earth's crust used to support our civilisation. Chromium is one of such very important metal, although it is very rarely used in its metal form, is an essential ingredient for stainless steel making. tool, and alloy steel, nickel–chromium heating elements, and plating metals.However, the chromite mineral is …
India is endowed with a reasonably large reserve of chrome ore, amounting to about 100 million tons in different grades and is one of the leading producers of ore/concentrate along with South Africa, Kazakhstan and others. Chromite production in India has registered a 10 times increase during the last 30 years. Till late 1940s, the practice was to mine the high-grade ore …
The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and agglomerated pellets (Iron and …

The run of mine (ROM) feed from underground is stored on a live stockpile before processing in a beneficiation plant. The crushed chrome ore is conveyed to a classification section where coarse and fines fractions are separated before being subjected to further processing i.e. Dense medium circuits, and mill & spiral section.
Prolonged development of ore deposits, ore beneficiation and metallurgical smelting of concentrates result in the accumulation of wastes, forming large-scale dumps and sludge ponds negatively affecting the environment and human health.
