And is counted. There is a considerable proportion of molybdenum ores in China, especially in Hebei, inner Mongolia with huge reserves of wrapping type low-grade molybdenum ores. For example, the improvement of leaching technology and the improvement of yield of certain uranium-molybdenum intergrowth ore in Hebei can greatly improve impurity ions in the leaching solution, so that the phase separation is unclear in the process of extraction in the downstream extraction process, and a large amount of three-phase matters are generated in the process of back extraction, thereby causing the loss of organic phases.
The traditional process flow of removing impurities from molybdenum ore leaching pulp is leaching pulp, adding carbide slag, filtering, adding flocculant, vacuum drum filtering and leaching liquid. The process flow leachate has higher turbidity and high impurity ion content, and increases the difficulty for downstream processes. The method for recovering molybdenum in the acidic molybdenum-containing solution generally adopts a selective precipitation method, an ion exchange method, an extraction method, an active carbon adsorption method and the like, and is commonly used as an ion exchange method and a solvent extraction method, but the ion exchange method and the solvent extraction method have strict requirements on leaching liquid. If a company in China uses tertiary amine as an extractant and acid organophosphorus to establish a synergistic extraction flow to carry out molybdenum extraction on sulfuric acid medium leaching liquid, but the molybdenum extraction phase separation is unclear in the extraction procedure, and the organic phase entrains water phase to make phase separation difficult in the pickling process. The molybdenum stripping three-phase produces excessive. Therefore, a process method for removing impurities from low-grade molybdenum ore acid leaching solution is needed.
