Chromite mining

Dec 11, 2020

The Thaba mine uses open pit mining to remove the chromite ore from the earth. These mines constitute the major production of the chromium. 2. Turkey. EtiKrom is the world’s biggest hard lumpy marketable chrome ore producer that can extract chrome throughout the year. Yildirim Group is also a major mines in Turkey that acquired EtiKrom in 2004

    The mining method used for extracting chromite depends greatly on the characteristics of the deposit. These characteristics include whether it is stratiform or podiform, high grade or low grade, subsurface or near surface, or massive or disseminated. Because surface mining typically is less expensive than underground mining, it is preferred
