For chromium salt preparation, the waterinsoluble Cr(III) (chromite) is converted into the watersoluble Cr(VI) in alkaline solution in the presence of an oxidant, followed by the separation of the insoluble gangue from the leachate containing Cr(VI) by physical separation.
Abstract SOME ASPECTS OF CHROMITE WITH REGARD TO POSS IBLE USES OF NORTH CAROLINA MATERIAL Minerals Research Laboratory January 1970 Progress Report Lab Nos. 3460, 3461, 3464, 3468,
The analysis controlled for smoking and infectious respiratory diseases. In a report of 10 cases of pneumoconiosis in underground workers in chromite mines in South Africa, radiographic analysis revealed fine nodulation and hilar shadows. Chromium in the chromite ore in South Africa was in the form of chromium(III) oxide.
