摘要
Abstract
One of Kazakhstan's paleo-channel sandstone uranium deposit has reduced uranium concen-trations(15-20 mg/L)and over 50％of wells exceeding their service life,affecting economic perform-ance and sustainability.To address these problems,technical measures were implemented:used oxi-dants during acidification to boost uranium concentration peaks and maintain higher levels;established a full-life cycle quality management system to increase the service life of drilling wells;carried out ad-vanced exploration to increase indicated and measured resources;and remined the low-recovery or multilayered orebodies.The results show these measures effectively improve resource recovery,lower operating cost,and extend mine life,supporting economic feasibility and sustainable operation.关键词
