Chromite mining The Oregon Encyclopedia

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.
