uranium mining and extraction from,acid leaching is sometimes also referred to as heap leaching because the leaching process can be performed on large 'heaps' of uranium ore that have been collected from mines. the chemistry of the leaching process revolves around oxidation of the uranium compounds, which is typically achieved using manganese dioxide (mno 2), sodium chlorate (naclo 3), and fe(ii) salts. [4] fig. 2 shows a typical reaction pathway for the acid leaching process.tailings.info hydraulic mining of tailings,a typical flow sheet for the reprocessing of tailings is shown below in figure 2. figure 2: simplified diagram showing the hydraulic re-mining of tailings. it can be noted that the use of hydraulic mining for tailings can be to either reprocess the waste, mine the waste as a product, or for moving of the tailings to a more suitable location..
