摘要
Abstract
Acid agitation conditional leaching test was carried out to extract uranium from a refractory uranium ore.Two leaching stage with a countercurrent solution flow process was developed.The technology process has been verified by small and industrial tests.The results show that sulfuric acid dosage by two agitation leaching stages with a countercurrent solution flow process was reduced to 11% from 12%,and uranium leaching efficiency was increased 2%.The average leaching efficiency is 92.5% by sludge calculation.关键词
