The effect of chromite ore granulometry and sintering process parameters was evaluated to improve the metallurgical performance of pellets in a submerged arc furnace. The …

Chrome ore properties play a critical role in various pelletisation subprocesses (grinding, filtering, pelletisation and sintering) and slight variation in ore properties significantly affect the whole pelletisation process.

More than 80% of the high grade chromite ores are fragile and tend to form fines during their handling. In order to utilise these chromite ore fine, in ferrochrome production, agglomeration is… Unique challenges of clay binders in a pelletised chromite pre-reduction process.

pellets produced were used in one of the furnaces for production of high carbon ferro chrome with 60-63% Cr content successfully. 2. PRODUCTION OF CHROME ORE SINTERED PELLETS …

Chrome ore fines and concentrates are dried to eliminate clogging of the downstream ball mill, reduce the corrosion of the grinding media and increase the amenability to the briquetting …

Granulometry of the chromite fines used for pellet production is an imperative enabler which controls the pellet strength and porosity by packing of particles and formation of …

Chrome ores are comminute, filtered, pelletized and sintered to use into submerged arc furnace for ferrochrome production. Variation in ore properties affects the particle size distribution …

pellets produced were used in one of the furnaces for production of high carbon ferro chrome with 60-63% Cr content successfully. 2. PRODUCTION OF CHROME ORE SINTERED PELLETS A study was made of the available literature and some …

Chrome ore fines and concentrates are dried to eliminate clogging of the downstream ball mill, reduce the corrosion of the grinding media and increase the amenability to the briquetting process by increasing the specific surface area available for binders to agglomerate the ore particles.

Pre-oxidation of chromite ore enhance chromite pre-reduction. Optimum pre-oxidation temperature was 1000 °C for the case study ore. Fe migration from the spinel must be maximised while avoiding Cr 2 O 3 formation. Improvement of 8.5% in electricity consumption can be achieved during smelting.
