Solid-state reduction ilmenite pressing block for producing titanium-rich material and preparation method and application thereof

Abstract

The invention discloses a solid-state reduction ilmenite pressing block for producing a titanium-rich material and a preparation method and an application thereof. The solid-state reduction ilmenite pressing block comprises the main following materials in percent by weight: 78.5%-82.5% of ilmenite powder, 10%-14% of coal powder, 3%-4% of borax, 0.5%-1.5% of NaCl, 1.0%-1.5% of iron red powder and 0.5% of iron powder. In the weight percentage, the sum of the weight percentage of the ilmenite powder and the weight percentage of the coal powder also needs to be ensured between 92.5%-95%, and the sum of the weight percentage of the borax, the weight percentage of NaCl, the weight percentage of the iron red powder and the weight percentage of the iron powder needs to be ensured between 5.0%-7.5%. The ilmenite pressing block is a mixture, is specially used for producing the titanium-rich material, and can be used for preparing a high-grade titanium-rich material, and simultaneously, the preparation process is low in pollution and low in energy consumption.

Description

technical field [0001] The invention relates to an ilmenite briquette and a method for preparing titanium-rich material by using the ilmenite briquette. Background technique [0002] With the development of the titanium industry, natural rutile resources with higher titanium grades are becoming increasingly depleted, which forces people to develop and utilize ilmenite resources with abundant reserves. Due to the low grade of ilmenite titanium, if it is directly used in titanium industrial production, there will be problems such as low efficiency, long process, large amount of "three wastes" and high cost. Rutile is then used in titanium industrial production. Therefore, it is of great significance for the development of the titanium industry to study the method of producing titanium-rich materials from ilmenite with high efficiency, energy saving and environmental protection. [0003] Most of the traditional methods of producing titanium-rich materials belong to the carbot...
