•Chrome fines generated from seams by a natural process of weathering. •Eluvials chromite concentrations vary between 3 and 30% Cr2O3 in the soils where they form an anomaly. Depth of eluvials vary by area but maximum recorded is •Eluvial are loed along the margins of the Dyke or in the transverse valleys or along watercourses
· As the majority of Cr rich Indian chromite ore are friable in nature and available in fine form, utilisation of chromite fines for production of superior quality ferrochrome is essential. For this purpose, in the present study, the smelting of chromite pellets, briquettes, sinter and lump ore has been carried out in an electric arc furnace of 50 kVA. The energy consumption, yield, .
· Scrapers haul chromite to ore passes that load trains on the haulage level. The trains load a conveyor in the hoisting adit. The dimensions in the Waterkloof/Millsell mining block have allowed WCM to replace scrapers with loadhauldump machines. The open cut mine uses 8tcapacity loading shovels and 40tcapacity trucks. Ore processing
The present invention relates to a process for the partial oxidation of unagglomerated chromite ore and to the use of the claimed process in currently applied ferrochromium production processes. According to a first aspect thereof, the present invention provides a process for the partial oxidation of chromite. The said process includes the steps consisting of: (i) providing a .

CIL gold processing plant mainly consists of following steps 1 The ore is first reduced in size typically 90 passing 200mesh to ensure that all non refractory gold is readily accessible for cyanide leaching There are several variations of comminution circuits used in the gold leaching industry such as Multi stage crushing then ball .
· Smelting chrome ore 855 Low carbon levels are more readily attained with a lumpy, coarse ore and when the slag has a MgO/Al^ ratio of approximately unity. Higher values of MgO/Al^ are especially deleterious. The presence of CaO also raises the carbon level. The influence of these factors can be explained by their effect on the temperature of reaction. From .
