Most of the uranium ore deposits at present supporting these mines have average grades in excess of 0.10% of uranium – that is, greater than 1000 parts per million. In the first phase of uranium mining to the 1960s, this would have been seen as a respectable grade, but today some Canadian mines have huge amounts of ore up to 20% U average grade.

This mine is the largest reserve of uranium in the country and its economic viability depends on the associated phosphate exploration. This means that the uranium extraction is subject to the production of phosphoric acid-raw material used in the production of fertilizers (agroindustry).

The first commercial production of phosphate rock began in England in 1847. A wide variety of techniques and equipment is used to mine and process phosphate rocks in order to beneficiate low-grade ores and remove impurities. The eighth chapter of this book deals with mining and beneficiation of phosphate ore. The principle and operating conditions of …

The pond at the abandoned phosphate mine sits in a stack of phosphogypsum, a radioactive waste product from fertilizer manufacturing. It contains small amounts of naturally occurring radium and ...

uranium-bearing phosphate beds. The present work used the integrated carborne c-ray spectrometric data, X-ray analysis and HPGe c-ray spectrometer data to investigate the radioactive zones at this area. Car-borne c-ray spectrometric survey revealed an increase of equivalent uranium, up to 182 ppm. Maps were

The phosphate companies are authorized for the possession of fixed industrial gauges containing radioactive materials and enhanced naturally-occurring radioactive materials. During this contracting history, the decommissioning of their uranium recovery operations was unique. Decommissioning is beyond the simple closing of the plant.
