Study on uranium extracting in ore and fluorin reducing in product

During uranium extracting produce of high fluorin content ore in one uranium mine in China, the ore pile's harden and the resin's agglomeration have engendered. The fluorin content of product "111" can’t meet the national standard. During uranium extracting test, small size ore heap leaching、leaching in series piles and piles’ turnover periodically have been used. The test results show that these measures can improve the economic index and benefit of uranium mine. Aim to the problem of product quality, the new method is used to decrease the fluorin content in product and the fluorin content in product can be decreased after treated and meet the national standard.
