Is milling in chrome ore more beneficial

Apr 28, 2020

Between World War I and the end of the stockpiling program in 1958, more than half of Oregon's total production of chromite came from Josephine County, followed by Grant County. Evidence of mining in the form of primitive roads, pits, tunnels, cabins, and mills can still be found on the landscape, including in the Kalmiopsis Wilderness
