Chromite mining
Most operations were small, and many investments found little return. When the grade of the chromite was low, mills were needed to concentrate the ore; miners often converted mills used for gold. During World War I and World War II, Oregon's contribution to the domestic production of chromite varied from one-fifth to one-quarter.

The sixth chromite seam in the Lower Group (LG6) is an important source of chromite ore and is the ore body extracted at the mine. In the Eastern Lobe, in the vicinity of the mine, the strike is nearly north-south, with a dip of approximately 10 degrees towards the west. The average thickness of the LG6 seam is about 1.86 metres in the mine area.

What do we know about Iron Chromate?
When chromite ore is exposed to aboveground conditions, Cr-III can be converted to Cr-VI, which is the hexavalent state of chromium. Cr-VI is produced from Cr-III by means of dry milling or grinding of the ore. This mostly has to do with the moistness of the milling process as well as the atmosphere in which the milling is taking place. A wet ...
