Mining

Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Chromite mining   The Oregon Encyclopedia

Chromite mining The Oregon Encyclopedia

Chromite mining. 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.
