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 my country to import To make up for the shortage of potash mines

[0019] The invention provides a technical scheme: a preparation method of langbeinite, comprising the steps of:

[0020] S1. Raw material preparation: The raw material brine is dynamically evaporated at multiple temperatures in the room to obtain the raw material ore in winter and summer, and the sulfate section ore S-4 and the carnallite section ore S-5 are tested for dynamic evaporation in summer;

[0021] S2. Preparation of langbeinite coarse ore: Mix sulfate section ore S-4 with carnallite stage S-5, then place the mixed ore in a ball mill, grind until 60% of the mineral particle size exceeds 40 mesh, and grind Put the good ore into a 2000ml beaker, add the starting mother liquid E-25, stir at a stirring rate of 250r / min, and react in a constant temperature water bath for 1h to obtain langbeinite coarse ore;

[0022] S3. Coarse ore flotation: place the above-mentioned langbeinite crude ore in an external flotation machine, use alkylmorpholine as collector and turpentine as...

Abstract

The invention relates to a preparation method of picromerite and a picromerite feed, and the preparation method comprises the following steps: S1, raw material preparation, wherein raw material brineis subjected to indoor multi-temperature dynamic evaporation to obtain raw material ores in winter and summer, namely, sulfate segment ore S-4 and carnallitesegmentore S-5 in the summer dynamic evaporation test;S2, the preparation of picromerite coarse ore, whereinthe sulfate segment ore S-4 and carnallitesegment S-5 are mixed together and then placed in a ball mill, the mixed ore are ground to the particle size of 60 percent of the mineral is over 40 mesh, and the ground ore is placed into a 2000 ml beaker; a starting mother liquor E-25 is added in the breaker at the stirring rate of 250 r / min and then the reaction for 1 hour in a constant-temperature water bath is performed to obtain picromerite coarse ore; S3, the crude ore flotation, where the picromerite coarse ore is placed into a flotation machine for flotation. The method uses sulfate lake resources to prepare picromerite and applies the prepared picromerite to the feed.

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 short columnar or thick plate, and the aggregates are blocky, powdery, and shell-like. 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, 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 langbeinite obtained by the exist...
