Problems solved by technology

At present, langbeinite at home and abroad is mainly obtained through the transformation and flotation of langbeinite, but the quality of langbeinite obtained by the existing preparation process is low, and high-grade langbeinite cannot be obtained, which leads to the need for China to import To make up for the shortage of potash mines

preparation example Construction

[0019] The preparation method of langbeinite of the present invention, comprises the steps:

[0020] S1, raw material preparation: collect the carnallite ore exposed to the sun in the salt lake and the tailing salt discharged to the tailings dam during production, as the raw material for the preparation of langbeinite;

[0021] S2. Transformation: Carnallite ore and tailing salt are mixed according to a mass ratio of 1.86, and converted for 90 minutes under the conditions of 49.8% water addition and 25° C., and the main solid phase substances obtained from the conversion of the mixture are composed of sodium chloride and langbeinite;

[0022] S3, flotation: use the solid phase obtained above as the flotation raw material, and the obtained liquid phase is used for flotation pulping, and the flotation raw material and flotation pulping are added to the flotation machine for flotation to obtain langbeinite concentrate mine;

[0023] S4, washing and drying: take the flotation con...

Embodiment 1

[0026] The preparation method of langbeinite: collect the carnallite ore exposed to the sun in Qinghai Salt Lake and the tailing salt discharged to the tailings dam during production as the raw material for the preparation of lensonite; mix the carnallite ore and the tailing salt according to the mass ratio 1.86 Mix and convert at 49.8% water and 25°C for 90 minutes. The main components of the solid phase obtained from the conversion of the mixture are sodium chloride and langbeinite; the solid phase obtained above is used as a flotation raw material, and the obtained liquid phase is used For flotation size adjustment, the flotation raw materials and flotation size adjustment are added to the flotation machine for flotation to obtain langbeinite concentrate; take the flotation concentrate, add 30% of water, wash at room temperature for 60 minutes, and remove the original solid phase A large amount of sodium chloride in the solution is dissolved into the liquid phase, and the wa...

Embodiment 2

[0029] The preparation method of langbeinite: collect the carnallite ore exposed to the sun in the salt lake and the tailing salt discharged to the tailings dam during production, and use it as the raw material for the preparation of langbeinite. The material composition of carnallite is 17.81% sodium chloride, 47.37% carnallite, 27.26% epsomium salt, 1.23% entrained mother liquor, 6.36% kabeinite; mix carnallite ore and tailing salt at a mass ratio of 1.86, and transform under the conditions of 49.8% water addition and 25°C 90min, the main substance of the solid phase obtained by the conversion of the mixture is sodium chloride and langbeinite; the solid phase obtained above is used as the flotation raw material, and the obtained liquid phase is used for flotation pulping, and the flotation raw material and flotation pulping Add it to a flotation machine for flotation to obtain langbeinite concentrate; take the flotation concentrate, add 30% water, wash at room temperature for...

Abstract

The invention relates to picromerite feed and a preparation method thereof. The preparation method includes the steps of S1, preparing materials, to be specific, collecting solarized carnallite from asalt lake and tail salt discharged to a tailings dam during production to provide materials for preparation of picromerite; S2, converting, to be specific, mixing the carnallite and tail salt in a mass ratio of 1.86, and converting under the water addition of 49.8% and the temperature of 25 DEG C for 90 min to obtain a solid phase converted from the mixture, wherein the solid phase mainly includes sodium chloride and picromerite. Carnallite of a salt lake and tail salt from production process are used to prepare picromerite herein; picromerite with the potassium yield of 54.9% can be attained; the picromerite prepared with the carnallite of the salt lake and the tail salt from the production process can be applied to feeds, thereby preventing fed animals from lacking potassium and experiencing muscular weakness, heart failure and respiratory failure; the problem is solved that picromerite prepared in the prior art has poor quality and causes insufficient potassium content to feeds, and therefore, normal growth of animals is affected.

Description

technical field [0001] The invention relates to the technical field of langbeinite preparation, in particular to a preparation method of langbeinite and a lenbeinite feed. Background technique [0002] Kobeinite is one of the main mineral components of potash ore. Monoclinic crystal system, the crystals are in the form of short columns or thick plates, and the aggregates are in the form of blocks, powders, and shells. Transparent colorless or white, light red, light yellow or gray when containing impurities. Vitreous luster. Hardness 2.5, density 2.03g / cm3. Heating easily loses water. When the temperature is low, primary deposits of soft magnesia are formed in the brine containing magnesia and magnesia. It can also be the weathering product of langbeinite and langbeinite, which is symbiotic with langbeinite, epsomite, and glauberite. At present, langbeinite at home and abroad is mainly obtained through the transformation and flotation of langbeinite, but the quality of...
