The in situ leaching uranium is environmentally friendly mining technique that contains mining, mineral processing and metallurgical technology, in which the leaching solution is directly injected into underground ore bed and the useful metal or compound is obtained through reaction between solutions and minerals. The ore-bearing strata pore structure feature and ore rock particle distribution directly affect the leaching rate of useful components. In order to study the ore-bearing strata ore rock structure feature and its effect on in situ leaching uranium, based on analysis of mercury penetr...
