Feasibility of Uranium Extraction from Oilfield Waters and Salt Lake Brines in Qaidam Basin

Abstract

Besides uranium ores and seawater,oilfield waters and salt lakes brine arc important uranium resources.The feasibility of uranium extraction from oilfield waters and salt lake brines in Qaidam Basin was analyzed.The chemical species of uranium in oilfield water and salt lake brines were predicted.A suitable uranium extraction method(adsorption) was proposed.Furthermore,the mechanisms and possible interferences on uranium extraction were prelimarily discussed.Finally,some suggestions on the research works of uranium extraction from oilfield waters and salt lake brines were presented.
