Smelting – Melting – Refining. ... Manganese commonly occurs in mineral chromite as an impurity, and the amount can range from trace quantities to a few percent. In ferrochrome smelting operations, the manganese should find its way into the slag rather than the metal. Data from these analyses have most often been used to trace the ...
In the Outotec® Fire Refining Process, the hot blister copper is charged into an anode furnace for purification. The refining is carried out in batches where the necessary oxidation and reduction stages are used to purify the copper.
At the smelter, charge chrome is produced through a single stage process by smelting a mix of chromite, reductant and fluxes at temperatures in excess of 2000°C. ... The two main products of chromite refining are ferrochromium and metallic chromium; for those products the ore smelter process differs considerably.

Two factors in particular have been identified as having an influence on carbon content; the particle size of the ore, and the MgO/Al^ of the slag. 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.
Chromite today is mined particularly to make stainless steel through the production of ferrochrome (FeCr), which is an iron-chromium alloy. Chromite grains are commonly found in large mafic igneous intrusions such as the Bushveld in South Africa and Travancore in India.
Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world’s chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.
chemistries, resulting in the production of ferrochrome alloys of varying composition and grade. The results of these campaigns primarily demonstrated the robustness and flexibility of the DC arc furnace for the processing of chromite ores and secondly provided a useful database pertaining to the smelting of chromite …
Chromite Market Summary ... the ore is brought to the surface and processed by ... gravity processes prior to smelting or refining into appropriate end uses. Get Price Chromite ore, Chromite is also used as a refractory material, because it has a high heat stability.
At the smelter, charge chrome is produced through a single stage process by smelting a mix of chromite, reductant and fluxes at temperatures in excess of 2000°C. Electrical energy, required for the chemical reactions to occur, is supplied to the submerged arc furnaces, through Söderberg electrodes.
Smelting – Melting – Refining. ... Chromite ore in combination with various quantities of magnesia is used in basic refractories. Refractories of this type are used as linings in steelmaking and copper smelting furnaces, rotary cement calciners, and glassmaking tanks. However, most of the consumption is by the copper and steel industry.
