African Chrome Fields currently holds hundreds of alluvial chrome mining concessions over an area of 20 km2 in the Great Dyke region of Mashonaland and Midlands provinces of Central Zimbabwe.
Jun 30, 2005· Sukinda chromite valley is one of the largest chromite deposits of the country and produces nearly 8% of chromite ore. It greatly contributes towards the economic development but at the same time deteriorates the natural environment. It is generally excavated by opencast mining method.
The bulk of chromite reserves are found in stratiform deposits (thin, even layers covering a broad area), but podiform deposits (scattered pod-shaped formations of varying size) are also important. Mining and concentrating. Chromite deposits are mined by both underground and surface techniques.
Open cast chromite mining generates large quantity of over burden. Overburden generation from the mining activities in Sukinda valley for the year 2005 is given in Table 1. If it is not protected/treated properly then runoff from these over burden can pollute the nearby surface as well as ground water bodies due to leaching of hexavalent
Because surface mining typically is less expensive than underground mining, it is preferred, but not always possible. Like mining, beneficiation (processing, crushing, separating, smelting, refining, etc.) for chromite depends on the characteristics of the ore deposit and on the mining methods used.
