A kind of environment-friendly smelting silicon ore catalyst and preparation method thereof

Abstract

The invention discloses a preparing method of environment-friendly smelting wollastonite accelerant. The preparing method includes the following steps that first processing equipment is vacuumized, nitrogen is introduced, and then the first processing equipment is preheated; copper powder, zinc powder and aluminum powder are mixed uniformly and put into the preheated first processing equipment, and the temperature of the first processing equipment and the content is raised to obtain a material A; then the material A is cooled and formed in a stretched mode to obtain a material B; the material B is used as the positive and negative poles of arc power consumption self-degrading, the positive and negative poles are put into second processing equipment at the same time, and then supersonic speed arc jet gas atomization is carried out on the material B to obtain the environment-friendly smelting wollastonite accelerant. The invention further discloses environment-friendly smelting wollastonite accelerant. The prepared smelting wollastonite accelerant is high in purity, high in fineness, capable of making full contact with wollastonite and suitable for a wollastonite smelting enterprise.

Description

technical field [0001] The invention relates to the technical field of catalyst preparation, in particular to an environment-friendly catalyst for smelting silicon ore and a preparation method thereof. Background technique [0002] In the process of extracting silicon from silicon ore, catalysts are often used as a means to accelerate the reaction and improve the purity of silicon. However, due to the large solid-solid phase particles, the catalyst cannot fully contact the silicon ore, resulting in waste of resources. The main components of ore catalysts are copper and zinc, which are extremely polluting to the environment. Therefore, it is necessary to develop a catalyst that can fully contact with silicon ore to maximize its effectiveness. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes an environmentally friendly catalyst for smelting silicon ore and its preparation method, which has high pu...
