THE LEACHİNG OF YTTRİUM FROM AVNİK (BİNGÖL TURKEY) APATİTE BY DILUTE SULFURIC ACID

In some countries the valuable elements such as uranium (U), vanadium (V), Fluor (F) and the rare earth elements are recovered from phosphate rocks as by-products. There is 0,32 % Y203 in Avnik Apatite in addition to 21,5 % P2O5. A sample taken from Avnik region was ground under 100 mesh size. The sample was leached with Solutions of sulfuric acid, and the effects of acid concentration, agitation time, and solid / liquid ratio on the efficiency of leaching were investigated. When 1 hour agitation time, 10 % solid/liquid ratio, and 0,3M of sulfuric acid as leach solution are applied then the best results of the leac¬hing of yttrium were obtained.
