Embodiment Construction

[0028] Below in conjunction with embodiment the present invention will be further described:

[0029] 1. The acidified potassium salt ore tailings ingredients are composed of the following components by weight percentage: acidified potassium salt ore tailings semi-finished product 96%, instant sodium silicate 2%, polyvinyl alcohol 1.5%, hydroxypropyl methyl Cellulose 0.49% and Sodium Carbonate 0.01%.

[0030] 2. The production method of the acidified potassium salt ore tailings: input the acidified potassium salt ore tailings ingredients into the mill for grinding, the particle fineness is ≤0.074 mm, and the powder after grinding is acidified potassium Salt mine tailings products.

[0031] 3. The production method of semi-finished potash tailings after acidification: (1) first input the mixture of potash tailings into the running mixer and stir, then slowly add dilute sulfuric acid into the mixture of potash tailings for acidification; (2) The potassium salt ore tailings mix...

Abstract

The invention discloses acidified potash salt ore tailing, and the key points of the technical scheme are that: acidified potash salt ore tailing ingredients comprise potash salt ore tailing, attapulgite clay, magnesium oxide, sulfuric acid, instant sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate. A production method of the acidified potash salt ore tailing is as follows: acidified potash salt ore tailing ingredients are transported into a mill for powder milling, and the milled powder is the acidified potash salt ore tailing. According to the production method of the acidified potash salt ore tailing, chemical reactions of sulfuric acid and instant sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate can be avoided. By acidifying treatment of the potash salt ore tailing, utilization ratio of the potash salt ore tailing can be improved, good economic benefit, environmental benefit and social benefit are brought, and the waste is turned into wealth. The acidified potash salt ore tailing has the characteristics of being good in adsorption, thixotropy, plasticity and adhesion, and is applicable to the production of nutrient soil, environmental protection materials and garden materials.

Description

technical field [0001] The invention relates to acidification treatment, in particular to acidified potassium salt ore tailings. Background technique [0002] Potash mine is a non-metallic mineral whose main components are potassium chloride and sulfate minerals. [0003] Potassium minerals mainly include potassium halite, carnallite, langbeinite, anhydrous langbeinite, polyhalite, langbeinite, kaleinite, etc. [0004] There are a large amount of potash mine tailings in the potash mine area, which have not been well developed and utilized. Contents of the invention [0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an acidified potassium salt ore tailing. [0006] The acidified potash tailings ingredients are composed of potash tailings, attapulgite clay, magnesium oxide, sulfuric acid, instant sodium silicate, polyvinyl alcohol, hydroxypropyl methylcellulose and sodium carbonate. [0007] The production method of ...
