Vanadium titano-magnetite smelting slag activation method

Abstract

The invention discloses a vanadium titano-magnetite smelting slag activation method, and belongs to the technical field of smelting slag activation. The vanadium titano-magnetite smelting slag is crushed to obtain vanadium titano-magnetite smelting slag powder, the vanadium titano-magnetite smelting slag powder is dried under a constant temperature condition to remove all adsorbed moisture in the material, and the vanadium titano-magnetite smelting slag powder is uniformly mixed with a synergist and then put into a microwave reactor for microwave treatment; and the powder and a grinding aid into a planetary ball mill, and ball milling is carried out under the protection of inert gas or in 10% air or air atmosphere. According to the method, the hydration activity of the surface of the powder is greatly excited, the specific surface area is greatly increased, the powder subjected to microwave treatment is further subjected to ball milling under the effect of the liquid grinding aid, static electricity on the surface of the powder with the high specific surface area can be effectively reduced, powder aggregation is prevented, and therefore, the vanadium titano-magnetite smelting slag micro-powder with high activity and high dispersity is obtained under lower power consumption, and high-quality treatment of the vanadium titano-magnetite smelting slag is realized.

Description

technical field

[0001] The invention relates to the technical field of smelting slag activation, in particular to a method for activating vanadium-titanium magnetite smelting slag. Background technique

[0002] my country's vanadium-titanium magnetite smelting history has been 40 to 50 years. In the long years, the solid industrial waste generated after smelting has reached about 100 million tons, and the annual rate is 5 million tons. The increase, piled up with large and small ravines in the production area, not only wasted precious land resources but also polluted the environment, urgently awaiting our comprehensive development and utilization.

[0003] my country's scientific and technological workers have never stopped research on the comprehensive utilization of titanium slag. Due to the special physical and chemical properties and mineral structure of titanium slag, no major breakthrough has been made. Chenggang has cooperated with many research and production units ...
