Pitchblende Uranium Ore

Uranium ores are apt to be covered with yellow spots, or crusts of uranite or uranium ocher. Other uranium minerals of a bright yellow color are known. The early discoveries of uranium minerals in Canada were in pegmatite dikes, in areas of eruptive granite. The feldspar in the neighborhood of pitchblende is usually darkened.

An Introduction to Uranium Ore Processing

The wet grinding circuits in most mills produce pulps of from 40% to 60% solids which are ready for leaching. In a few cases, where grinding is more difficult and the classifiers or cyclones overflow at a more dilute pulp density, it is necessary to thicken ahead of leaching. LEACHING The extraction of uranium from ore is accomplished

Occupational Safety in Uranium Mining

The product of uranium mining is normally uranium oxide concentrate – U 3 O 8 – which is shipped from the mines in 200-litre drums. This is barely radioactive, but has chemical toxicity similar to lead, so occupational precautions are taken similar to those in a lead smelter. Most of the radioactivity from the ore ends up in the tailings.
