Carnotite ore crusher and grinder are used in mining and concentration of carnotite. Carnotite is usually found as a yellow powder encrusting or filling the interstices between the grains or the cracks in a sandstone. It may also encrust or fill cavities in silicified wood included in the sandstone. Occasionally loosely coherent earthy masses an inch or two thick are found, sometimes associated with roscoelite. Microscopic examination proves that the mineral is crystalline and has a scaly form.

The process of crushing and grinding carnotite ore
The hand-sorted shipping-grade ore as it came from the mines consisted of lumps that would pass through rings 1 to 3 inches in diameter, mixed with finer material. The coarse ore, previous to chemical treatment, has to be ground, and at first the ore, after having been crushed to 1/4-inch size, was ground to pass a 40-mesh screen.
