Problems solved by technology

[0004] The present invention aims at the problem that the existing high-temperature calcination cannot destroy the stable silicon-oxygen tetrahedral structure of tourmaline, which causes boron in it to be difficult to dissolve and be utilized. A physical and chemical method is adopted to add hydrofluoric acid or fluorite to tourmaline. Add sulfuric acid or fluorosilicic acid to activate the reaction, so that the silicon-oxygen tetrahedron in the tourmaline is destroyed and escapes as gaseous silicon tetrafluoride, while the boron in the tourmaline is dissolved in the solution

Embodiment 1

[0011] Take 100 grams of tourmaline powder crushed into 100 meshes and slowly add 80 grams of hydrofluoric acid with a volume concentration of 50% at 20°C to react for 1 hour. , High activity tourmaline boron fertilizer can be obtained by granulation.

Embodiment 2

[0013] Take 100 grams of tourmaline powder crushed into 150 mesh, slowly add 150 grams of silicofluoric acid with a volume concentration of 30% at 150°C and react for 2 hours, after fully reacting, add 50 grams of tourmaline powder crushed into 150 mesh, 40 grams of urea , stir and mix evenly, and granulate to obtain highly active tourmaline boron fertilizer.

Embodiment 3

[0015] Get 100 grams of tourmaline powder crushed into 120 meshes and 100 grams of fluorite powders crushed into 80 to 100 meshes and mix evenly. Slowly add 150 grams of sulfuric acid with a volume concentration of 98% to the above mixture at 30°C and react for 48 hours. After the reaction is completed, Then add 400 grams and be ground into 150 mesh tourmaline powder, 40 grams of urea, 30 grams of superphosphate, stir and mix evenly, and granulate to obtain high-activity tourmaline boron fertilizer.

Abstract

The invention discloses a tourmaline activating disposing method, which comprises the following steps: adding fluohydric acid or silicofluoridein or fluorescent stone and hydric sulphate in the tourmaline; releasing boron. The preparing method of high-activity tourmaline boron fertilizer is characterized by the following: activating tourmaline to dissolve boron element; increasing boron releasing quantity of tourmaline by 22 times than original ore; keeping tourmaline illuminating infrared negative ion; accelerating plant root growth.

Description

(1) Technical field: [0001] The invention relates to an ore treatment method, in particular to a tourmaline activation treatment method; the invention also relates to a highly active tourmaline boron fertilizer prepared by the method. (two) background technology: [0002] Tourmaline is an iron-aluminum-borosilicate mineral with a complex structure. It has piezoelectric and pyroelectric effects, can emit 4-14 μm infrared rays, and can instantly negatively ionize water. In addition, it is also rich in trace elements. Such as Na, Fe, Mg, Mn, Li, B, etc., among which the boron content is as high as 6-12%, which is a very potential boron resource. As a fertilizer, tourmaline can stimulate the development of plant roots, increase the dissolution of beneficial minerals in the soil, and locally increase the soil temperature. Therefore, tourmaline has been widely used in the preparation of soil fertilizers. For example, the application number is: 01113963.3, and the name is "Tourmali...
