grinding takes place it reports to the final concentrate in the form of entrainment. The chrome occurs in the ore as a chrome spinel with iron oxide and only melts at temperatures exceeding 1600deg C. In contrast the furnaces utilized in the platinum industry
A statistical analysis of the recoveries showed that this change in grinding chemistry resulted in improvements of 1.0 and 1.3 percent, for copper and gold respectively. It was also noted that the final copper concentrate grade improved by at least 0.7 percent.
In order to produce directly marketable chrome ore for export and domestic industries, most of the chromite ore beneficiation plants in Sukinda region treat selected rich ores with rejection of huge quantities of low and sub-grade ore (10-38% Cr203).
· 1 Ore particle size In the most grinding process of the concentrator, the construction investment and production and operation cost of grinding operation is much higher than those of crushing operation, so it is necessary to reduce the grinding particle size as much ...

· Odisha state is the major reserve of the chromite ore. Due to the extensive applications, high-grade chromite ore is getting depleted day by day. Now it is a challenge for the industry to utilize these low-grade ores and tailings. Several attempts were taken to upgrade the low-grade chrome ores and tailings using different gravity separation methods, magnetic separation methods, flotation, etc ...
In chrome ore beneficiation, specific gravity and size-based separations are the most convenient and cost-effective methods [3, 4]. Majority of chromite ore beneficiating companies are searching for an economic way of beneficiating of ultrafine chromite
· The grinding media may be the ore itself (autogenous grinding), bars, balls, or cylpebs, or even the ore itself together with a small amount of balls (semi-autogenous grinding). A survey found out that approximately 53% of the grinding circuits around the world use ball mills, and 38% use autogenous or semi-autogenous grinding, and therefore nearly 90% of mining operations are users of balls ...
· Approximately 150 pounds of ore were stage crushed with rolls to minus 35 mesh, then blended and sampled for screen analysis. The results of the screen analysis, given in table 2, show that 48.3 pct passed 100 mesh, the point of chromite liberation. The minus 35-mesh stage crushed ore was slurried and tabled to produce a rougher concentrate.
