In the Great Dyke of Zimbabwe, the principal platinum group element (PGE)–bearing horizon, termed the main sulfide zone, is hosted in orthopyroxenites (Prendergast and Wilson, 1989).PGE mineralization has been demonstrated to occur bimodally in mafic-ultramafic intrusions, either hosted by sulfides or as discrete platinum group minerals.
Chromium. Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world''s chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.

Geologists estimate that there are about 11 billion tons of chromite mining sites all over the world. Over 90% of the chromium reserves are deposited in South Africa and Zimbabwe. Even though China is the largest consumer of the chromium, The United States of America, Kazakhstan, South Africa and India are the largest chromite mining producers ...
Domestic mining for chromite was restricted to a few locations in the United States, including Montana, California, and Oregon, and mining the mineral was only economically feasible during times of political conflict. During wartime, the United States government supported domestic production with price supports and strategic stockpiling programs.

The Valley Chrome Mine is near Gweru, Zimbabwe. The Valley Chrome Mine is a underground mining operation. Initial production took place in 1970. Mine operations consist of underground workings. There is one known shaft. The mining method is sublevel. Mine capacity in 1981 was 200 mt ore/day with a production unit cost of 18.71 $/mt ore.
Chromite, the principle ore of the element chromium, is a commercially valuable mineral. However, due to mining restrictions and the fact that Chromite is not commonly found in crystallized form, it is not well-represented in mineral collections. Chromite is isomorphous with the mineral Magnesiochromite and is easily confused with it, as they ...
