    To find the mineral, miners searched for a small piece of ore called “float” and followed it to the deposit, which is often in the shape of a lens-shaped “pod.” They worked small isolated deposits with hand tools. Larger deposits justified the cost of using dynamite, air compressors, jackhammers, and loading shovels/excavators

    The deposits of the chromite are generally removed by surface and underground mining techniques. The podiform deposits are generally mined by surface mining technique while the underground mining is employed to stratiform deposits. Open pit mining: The layers covering the ore of the chromium are first removed to reach the ore
