[0039] The raw materials of this example are weighed according to the weight parts of straw, fibrous stalks, heat-clearing herbs, Rhododendron herb, and fungi in order of 30 parts, 65 parts, 0.5 parts, 4.42 parts, and 0.08 parts, and are weighed after drying. After pulverization, the Dujing herb powder is mixed with water first, and then mixed with other raw materials evenly, and water is added at the same ...

Embodiment 3

[0041] The raw materials used in this embodiment are as follows:

[0042] The straw is corn stalk.

[0043] The fibrous stalk is a mixture of tea bran, wheat bran and peanut bran in a weight ratio of 1:1:1.

[0044] The heat-clearing herb is Sapindus chinensis; the Rhododendron family herb is a composition of Vitex chinensis and Vitex vitae in a weight ratio of 1:1; the fungus is a mixture of mushrooms and yeasts in a weight ratio of 1:1, and the mushrooms are collybia spp. and Pleurotus ostreatus , Anchovy mushrooms are mixed according to the weight of 1:1:1.

[0045] The raw materials of this example are weighed in order of 40 parts, 58.5 parts, 0.5 parts, 0.5 parts and 0.5 parts according to the weight parts of straw, fibrous stalks, heat-clearing herbs, Rhododendron herbs, and fungi, and weighed after drying. After pulverization, the Dujing herbal powder is mixed with water first, and then mixed with other raw materials evenly. Water is added at the same time when mixing...

Abstract

The invention relates to the field of preparation of rare earth, in particular to a herbaceous plant rare-earth precipitating agent and a preparation method thereof. The herbaceous plant rare-earth precipitating agent is prepared from, by weight, 30-50 parts of straw, 25-65 parts of fibrous stalks, 0.5-5 parts of herb for clearing away heat, 0.5-5 parts of Vitex.negundo L.var. cannabifolia (sieb. et Zucc.) Hand.-Mazz. herb and 0.08-5 parts of fungi, and the raw materials are weighed, smashed, fermented and soaked so that the herbaceous plant rare-earth precipitating agent can be prepared. By means of the herbaceous plant precipitating agent, the mother liquid precipitating effect can reach 99.6% or above after mineral leaching is performed on rare earth minerals in different types, the concentration of ammonia and nitrogen in supernatant after precipitation is 0.94 mg / L, secondary pollution of ammonia and nitrogen is avoided, herb precipitate contained in the supernatant can be directly used circularly, and the herbaceous plant rare-earth precipitating agent is a natural and environment-friendly precipitating agent.

Description

technical field [0001] The invention belongs to the field of rare earth production, in particular to a rare earth precipitant for herbal plants 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. Heavy rare earths are mostly ionic, and their mining process is different from that of light rare ...
