Abstract:This is an essay in the field of mining engineering, which takes Panxi vanadium-titanium magnetite associated sulfur resources as the research object, and expounds its comprehensive utilization path and its low-carbon development significance. Sulfur is one of the typical associated elements of Panxi vanadium-titanium magnetite, and it is also a port element of the emerging industrial chain of food-resource-energy in the double carbon era. Based on the endowment conditions of Panxi vanadium-titanium-magnetite associated resources and the occurrence status of sulfur minerals, this paper analyzes the current situation and characteristics of associated sulfur resources, and uses the mining and dressing industry chain of vanadium-titanium magnetite to discuss the possible environmental impact of sulfur in the process of comprehensive utilization. The comprehensive utilization potential analysis is discussed from two aspects of mineral product demand and comprehensive utilization maturity risk assessment. Under the circumstances that associated sulfur resources are facing the challenge of green and low-carbon development, this paper puts forward comprehensive utilization suggestions from the three aspects of planning top-level design, technical research, and production line promotion, aiming to promote the development of the sulfur industry guided by the principle of green and low-carbon, Focus on promoting carbon reduction and pollution reduction through source sulfur selection production line intervention. The research in this paper can provide new ideas and specific suggestions for the comprehensive utilization of sulfur resources associated with vanadium-titanium magnetite, environmental planning and low-carbon development.
