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 DOMBP’s tailings mineral resources, which have been accumulated since 1938, amount to 2.2 million tons as of 1 January 2018. In total, there are 2.2 million tons at 27.65% Cr 2 O 3, which is 0.6 million tons in terms of chromium oxide [].The technological scheme of chrome ore processing at DOMBP includes standard operations of gravity Recycling of Chrome-Containing Waste from a Mining and Processing Plant

However, these techniques become inefficient and complex when treating fine and ultrafine size particles (less than 75µm) resulting in this size fraction lost to the tailings. As a result, a wet magnetic separation technology for recovery of ultra-fine chromite (Cr 2 O 3) from spirals tailings as a scavenger was investigated.Vulcan fine chrome recovery plant . The first of these is the Vulcan plant, which will facilitate additional recovery of fine chrome from tailings streams.

The tailings and dump material, due to their fine particle size, mean that the coarse material accounts for only some 28% of the total with the rest being free issue. The material contains about 28% chrome content at this stage.
