mine produces 3 grades of chrome ore, namely lumps, chips, and concentrates. The lumps and chips of chrome ores are used as raw material and are directly fed in submerged arc furnace, while the concentrates of chrome ore must undergo agglomerating treatment, such as sintering or pelletizing. Due . Chrome Ores on Ferrochrome Smelting
Dec 07, 2017· Non alloy steel is a type of steel that has no other elements added during smelting. Smelting is the process of extraction of a metal from its ore. This process involves heating and melting the ore. Smelting removes impurities present in the iron ore. The smelting process is done several times in order to remove the carbon.
Low cost ferroalloy extraction in DC-arc furnace at Middleburg Ferrochrome by D. Sager, D. Grant†, R. Stadle*, and T. Schreiter‡ Synopsis Middleburg Ferrochrome (MFC), a company in Samancor Chrome, commissioned a new ferrochrome smelter in March 2009. This is a 60 MW DC-arc furnace with a DC power supply for the smelting of
Outotec DC Smelting Plant. Use a cost-efficient, sustainable, and compact solution for ferroalloys processing. Outotec's direct current (DC) smelting furnace can be used for direct smelting of fine ores, even those with highly variable chemical or mineralogical compositions, as well as for recycling challenging by-products such as steel dust.
ore and nickel ore, as well as steel-plant dust. OUTOTEC STEEL BELT SINTERING BENEFITS • Transform problematic fines into profit-able pellets • Produce consistently high-quality pellets ideal for use as smelting charge material • Fulfill strict environmental require-ments with efficient off-gas cleaning and low water consumption
An intermediate process which upgrades the ore to a saleable intermediate product is viable. This process has lower capital requirements than that of charge chrome smelting. The process effectively utilizes the substantial cost and environmental benefits of natural gas for energy. The need for subsidized electrical energy is eliminated.
Because Si and C have to be refined away by the steelmaker, it is desirable to reduce their concentrations to the lowest level consistent with the lowest cost of smelting. SMELTING REACTIONS In the smelting process the electric furnace is charged with the chrome ore, a carbon reducing agent, and a flux, usually quartz.
ferrochromium – Pretreatment for smeltinG particularly the case with the AC SAF (Submerged Arc Furnace) and only to a very limited extent with the DC arc furnace. Alternative processes that have been used or have been partly developed include the CDR (Chrome
Zimbabwe Mining and Smelting Company (Zimasco) chief executive John Musekiwa told a recent mines conference that while Government's thrust of value addition will decrease chrome ore exports, it will, however, drive ferro-chrome exports.

ChromTech believes that DC technology is currently the only low cost technology that provides a differentiated product (low silicon and phosphorous), requires no agglomeration and results in higher chrome recoveries in terms of ferrochrome production.
LEAD SMELTING PROCESS - Cominco Ltd. Nov 12, 1974· A process for separately recovering lead values and sulphur values from lead sulphide ores and concentrates in which ore or concentrate in particulate form in admixture with an oxygen-rich gas is charged into a furnace containing a molten bath consisting of lead oxide-containing slag or of lead and a lead oxide-containing slag cover.
South African chrome ore will become the dominant source for ferrochrome production. Factors such as geology, mining methods, beneficiation and chemistry of the ore are discussed. The effect of chrome/iron ratio on the cost of ferrochrome production is analysed in detail. I. Introduction
Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation.
