Sintering Characteristics of Indian Chrome Ore Fines

2009-8-11 · Studies carried out by the authors show that it is possible to agglomerate chrome ore fines through sintering. The chrome ore sinter thus produced was found to be inferior in strength, comparable to that of an iron ore sinter, but strength requirements may not be the same for both.

Smelting of high-carbon ferrochrome from chromium

2017-4-28 · In a test melts, high-carbon ferrochrome is produced from chrome sinter and chrome-ore fines in an arc electrofurnace. Two types of sinter with the best performance—the best sintering rate, strength, and product yield—are studied. It is demonstrated by experimental melts that high-carbon ferrochrome can be produced from proposed agglomerates.

Process for the oxidative dissociation of chrome

A process for the oxidative dissociation of chrome-containing ores comprising agglomerating a mixture of a chrome-containing ore, an alkaline substance and a moist solid residue from a preceding operation as a leaning agent, dissociating the agglomerate and then leaching to form a solution of chromate and a solid residue, and separating said solution from said solid residue still wet with said

Development of Chromite Sinter from Ultra-Fine

agglomerate chromite ore fines through sintering. Perfor-mance study of this sinter in a laboratory-scale EAF showed that the specific power consumption in the melting was comparable with that of the heat-hardened chrome ore pel-lets and lower than the briquettes and lump ores. They also reported that chromite sinter can reduce the unit electricity

2018-1-20 · Das (2015) also reported a study on the characterization of chrome ore plant tailings and revealed that chromite, goethite, and gibbsite are major mineral phases present in the plant tailings while others identified as minor phases . The BET surface area of chromite ore tailings is 23.79 m 2 g −1, and the particle density was 3020 kg m −3.

Beneficiation and agglomeration process to utilize low

2011-5-8 · The recovered ore concentrate can be briquetted using a combination of molasses (7%), cement (3%) and bentonite (1%) to produce suitable agglomerate for metallurgical applications. The process flow sheet shown in Fig. 6 has been proposed and tested at a plant scale to utilize low grade manganese ore fines. It was found that these agglomerates can successfully replace 15% of high grade lumpy ores, which, can reduce the ore
