Distribution characteristics of minerals and elements

2012-1-10  In this paper, environmental scanning electron microscopy (ESEM) is applied to characterizing the mineral and element distribution of chromite ore processing residue (COPR). The test results show that Cr-bearing brownmillerite occurs in the rim of COPR particle, while hydroandradite with Cr (VI) in its structure presents inside the COPR particle.

Oxidation decomposition of chromite ore in molten

2007-7-4  Traditionally, chromite ore is processed with the addition of limestone and dolomite at about 1373 K in a kiln or rotary furnace, with low utilization efficiency of resources and energy, producing a hazardous residue containing about 5% chromium, e.g., CaCrO 4 which is harmful to the environment.

Reducing energy consumption by alternative

The chromite reserves already discovered in the Ring of Fire region indicate that the tonnage of ore is sufficient to sustain production over many decades, and well into the next century. A process which is sufficiently advanced to retain a competitive advantage far into the future is essential, and will remain competitive long after the logistical and infrastructural issues are resolved.
