Sintering ore and production method thereof

Abstract

The invention provides a sintering ore and a production method thereof. The production method comprises the following steps of: mixing the following materials in parts by weight to form a mixture: 55-60 parts of ilmenite powder containing vanadium, 1-3 parts of vanadium extraction tailings, 3-5 parts of blast furnace gas ash, 4-7 parts of limestone, 5-7 parts of coke powder, 9-23 parts of Australian ores and 4-6 parts of active lime; and putting the mixture into a sintering machine, and sintering the mixture at a sintering ignition temperature of 1050-1200 DEG C to prepare the sintering ore. The sintering ore consists of the following components in percentage by weight: not less than 49.5% of TFe, 5-8% of SiO2, 9-12% of CaO, 2-4% of MgO, 5-8% of TiO2 and 0-1% of V2O5, and the alkalinity of the sintering ore is 1.8-2.1. The production method has the advantage that the sintering ore can be prepared by effectively using solid wastes namely the vanadium extraction tailings during the production of vanadium products on the basis of ensuring that the grade of the sintering ore is not lowered.

Description

technical field [0001] The invention relates to a resource utilization technology of solid waste in the metallurgical industry, in particular to a sintered ore utilizing tailings from vanadium extraction and a production method thereof, belonging to the fields of metallurgy and environmental protection. Background technique [0002] my country is a country rich in vanadium and titanium resources. The utilization of vanadium is generally to produce vanadium oxides from vanadium slag through ball milling, roasting, leaching and other processes, and then proceed to the subsequent production of vanadium products. In the production process of vanadium oxide, solid waste-vanadium extraction tailings will be produced. The TFe in the vanadium extraction tailings reaches about 30%, containing SiO 2 16% to 19%, and there is a certain amount of MnO, and more importantly, it also contains V 5+ 、Cr 6+ Such as ions that will pollute the environment, if not utilized, will have a negative...
