The cycle Ⅶ of a deposit is suitable for low sulfuric acid concentration leaching. The rapid acid consumption obtained from the ore agitation leaching test is characterized by step with the increase of acid concentration of leaching agent. The change of uranium leaching rate and mineral dissolution corresponds to acid consumption step characteristics. High acid consumption step can cause CaSO4 precipitate. The corresponding acid concentration of each acid consumption step respectively guides the selection of acid concentration of leaching agent for acidification stage, formal leaching stage, and prevent the lower permeability of ore bed. The method of definition the acid concentration range of the liquid injection was further verified by field test.
