Abstract

The invention relates to the field of rare earth mineral leaching, in particular to a herbaceous plant rare-earth mineral leaching agent and a preparation method thereof. The herbaceous plant rare-earth mineral leaching agent is prepared from, by weight, 50-90 parts of straw, 8-35 parts of fibrous stalks, 1-10 parts of distillers' grains, 0.5-5 parts of oxalis corniculata, 0.08-0.5 part of fungi and 0.05-3 parts of traditional Chinese medicine herb, and the raw materials smashed, fermented and soaked so that the herbaceous plant rare-earth mineral leaching agent can be prepared. By means of the herbaceous plant mineral leaching agent, the leaching effect on rare earth minerals in different types can reach 94% or above and can reach 99.98% to the highest extent, the leaching effect is improved by 12% or above compared with the leaching effect generated when the same amount of 2% ammonium sulfate is used, the peak value of the content of ammonia and nitrogen in the herbaceous plant mineral leaching agent is far lower than the peak value of the content of ammonia and nitrogen generated when 2% ammonium sulfate is used in the mineral leaching process, and the herbaceous plant rare-earth mineral leaching agent is a natural and environment-friendly mineral leaching agent.

Description

technical field [0001] The invention belongs to the field of rare earth ore leaching, in particular to a herbal plant rare earth ore leaching agent and a preparation method thereof. Background technique [0002] Rare earth is composed of 15 elements in the lanthanide elements in the periodic table of chemical elements plus two other elements related to it, a total of 17 elements, namely: lanthanum (La), cerium (Ce), praseodymium (Pr), Neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), Ytterbium (Yb), Lutetium (Lu), Yttrium (Y) and Scandium (Sc). Referred to as rare earth (RE or R). [0003] my country's heavy rare earths account for more than 70% of the world's total heavy rare earths. It is an important and precious wealth of mineral resources bestowed by nature on our country. Most of the heavy rare earths belong to the ionic type, and their mining technology is differe...
