Mineralogical and image analysis study of artificially weathered tailings from the Midwest uranium ore in Saskatchewan / W. Petruk and R.G. Pinard. : M38-13/88-6E-PDF
"A mineralogical and image analysis study was conducted on samples of U tailings from pilot-plant runs on Midwest ore in Northern Saskatchewan. The tailings had been subjected to simulated weathering for the equivalent of 10 years in a tailings facility (lysimeter); the pH varied from 7.0 at the beginning of the test to 5.9 at the end. The results show that during the simulated weathering some of the gersdorffite, uraninite, galena and pyrite had oxidized, with gersdorffite being the most reactive and pyrite the least. Reaction was evident at the top of the lysimeter, but was most intense at the seepage discharge. Some of the released ions precipitated as Ni, Pb, and U arsenates, sulpharsenates, sulphates and oxides on particles of all minerals. Green crystals of Ni sulphate and white crystals of Ca sulphate had precipitated at the surface of the lysimeter. Clay minerals and chlorite had washed from the top of the lysimeter towards the seepage discharge"--Abstract, p. i.
