Process for producing amorphous silicon-kalium fertilizer

Abstract

The present invention relates to potash fertilizer production, and is especially the production process of non-crystalline silicon potash fertilizer. The present invention utilizes new type of catalyst in converting the crystalline structure of potash feldspar into non-crystalline structure, so as to make the potassium ion replaced easily with other cation to become effective potassium.

Description

technical field [0001] The invention belongs to the field of potash fertilizer production, in particular to a method for producing amorphous silicon potash fertilizer. Background technique [0002] my country's insoluble potassium-containing rock resources are very rich and widely distributed. The development and utilization of insoluble potassium resources to produce potassium fertilizers is an effective way to solve the shortage of potassium fertilizers in my country. However, my country lacks soluble potassium salts for the production of silicon-potassium fertilizers. Domestically produced potassium fertilizers are rare and mainly rely on imports. . [0003] Since the 1950s, my country began to explore the production methods of using insoluble potassium ore resources to produce agricultural potassium fertilizers, such as lime kiln calcination. These methods are small in scale, low in technical content, and poor in effect, and have not formed industrialized production. In ...

Problems solved by technology

[0005] Except for biological potash fertilizer products, most of them are experimental researches, and industrial production has not been realized, and the output of biological potash fertilizers is less than one percent of the domestic potash fertilizer market.
