Embodiment 1

[0042] Using 1# molten converter vanadium slag, its composition is TFe 37.00%, MFe 14.00%, FeO 29.57%, V 2 o 5 17.32%, SiO 2 16.23%, MnO 10.28%, TiO 2 8.43%, other 4.17%; aluminum ash 1 component is SiO 2 5.42%, Al 2 o 3 38.53%, Al 28.25%, (FeO+Fe 2 o 3 ) 0.74%, CaO 1.52%, MgO 2.52%, Na 2 O2.82%, MnO 0.86%, others 19.34%.

[0043] The method for comprehensive recycling of vanadium slag and aluminum ash valuable components comprises the following steps:

[0044] A. Raw material preparation and charging: Prepare molten vanadium slag, lime and aluminum ash, first put lime and aluminum ash into the electric furnace, then pour molten vanadium slag, the amount of lime and aluminum ash added is 15% of the total weight of vanadium slag And 70%, particle size ≤ 100 mesh.

[0045] B. Heating reduction: After charging, heat the electric furnace to 1500°C and keep it warm for 1.5 hours to reduce the valuable components iron, manganese and vanadium in aluminum ash and vanadium...

Abstract

The invention discloses a method for recovering valuable components in vanadium slag, which belongs to the field of metallurgy, and is a method for recovering Fe-V-Mn alloy in molten vanadium slag by using aluminum ash reduction. The invention can make vanadium slag, Valuable resources such as iron, vanadium and manganese in aluminum ash are effectively recovered, and the tailings produced at the same time can also be reused, realizing the comprehensive utilization of vanadium slag resources, taking into account the ecological characteristics of "resources + energy", with simple process, Advantages of low production cost, energy saving and emission reduction, and zero pollution.

Description

technical field [0001] The invention relates to the comprehensive utilization of metallurgical solid waste resources, in particular to a method for treating vanadium slag, which belongs to the field of metallurgy. Background technique [0002] Vanadium is an important strategic material, widely used in steel, chemical, aerospace and other industrial fields. With the acceleration of the process of global economic integration and the rapid development of my country's market economy, the demand for vanadium products is becoming more and more intense. my country's vanadium resources are mainly associated with iron and other elements in nature, and occur in vanadium-titanium magnetite, accounting for about 45% of my country's vanadium resources. At present, the treatment process of vanadium-titanium magnetite in my country is mainly to extract vanadium-containing iron ore through the blast furnace-converter-vanadization process, in which the vanadium-containing iron ore is reduc...
