Research progress on vanadium-titanium-iron tailings-based building materials
The deep development of ultra poor iron tailings generates a large amount of tailings and the environ-mental and safety issues caused by tailings discharge are particularly prominent.How to efficiently utilize a large amount of stacked vanadium titanium iron tailings is a common challenge facing the development of tail-ings based building materials.Most scholars believe that vanadium titanium iron tailings contain a large amount of inorganic minerals such as silicon and aluminum oxides,which are similar to the raw materials of many building materials.After mixing them with a small amount of other auxiliary materials,they can be used as raw materials for many non-metallic materials.After certain technical treatment,ideal building materials can be obtained.However,relevant research mainly focuses on the feasibility of using tailings as building mate-rials,neglecting the overall technical and economic benefits of mineral processing tailings resource utilization.There are still certain problems in large-scale industrial production and application.How to better coordinate the contradiction between the performance and economic benefits of tailings based building materials,and achieve the reduction,harmless and resource utilization of vanadium titanium iron tailings is still the main top-ic for further research by solid waste utilization workers.
