Ore Dressing Research Papers

Washeries were installed near the mines, usually in an arid environment. To overcome the problem of water, many hundreds of cisterns associated to ore dressing workshops (Ergastiria) were constructed, where water was collected during the rain periods and stored during the whole year for the operation of the washeries.

Nigeria's Phosphate and Uranium Mineral Occurrences

phosphate rock deposits provide 75% of the world's phosphate resources, while 15 – 20 % come from igneous and weathered deposits and only 1 – 2% from biogenic (mainly from and bat guano accumulations) resources (van Straaten, 2002). In Nigeria, the phosphate deposits are of the sedimentary, marine origin. In

APATITE AND ROCK PHOSPHATE Indian Minerals …

Phosphate rock is also the source of by-product fluorine. Apatite & rock phosphate containing 3 to 4% CaF 2 are useful for recovery of fluorite. Hydrofluoro-silicic acid is recovered as by-product from phosphoric acid plants during processing of rock phosphate. Phosphate rocks are also considered as a significant and secondary resource of uranium.
