随着美国对铀需要量的增长,铀价格也很快提高了,这刺激了地质找矿和对低品位铀矿的开发。铀水冶厂向更大的处理量发展,加之许多新近制定的环保条例,使水冶费用成为当前铀生产经济的重要因素。下面评述从铀矿石中提取铀的三个常规流程。 As the U.S. demand for uranium increased, uranium prices also increased rapidly, stimulating geological prospecting and the development of low-grade uranium deposits. Uranium hydrometallurgy to a larger capacity development, coupled with many of the newly enacted environmental regulations, making hydrometallurgy into the uranium production economy is an important factor. The following is a review of three general processes for extracting uranium from uranium ore.
