Summary of heap leaching, refining, and converting intermediate plants 1. Comprehensive processing system and main equipment At present, Japan’s policy is to preserve most of the humanoid (?) For uranium mines, only a small amount of ore is mined for heap leaching and testing (about 5,000-10,000 tons per year, with a quality of 8/10,000). Most of the uranium needed for the conversion of the plant (about 100-200 tons per year) is provided by yellow cake imported from abroad and dissolved in the middle of the process.
