Tungsten associated resources comprehensive recycling utilization

China tungsten ore mostly are skarn tungsten deposits, hydrothermal filling and polymetallic tungsten deposit and so on. Wolframite is usually associated with molybdenum, tin, bismuth, copper, lead, zinc, niobium, tantalum, and gold, silver and other metals.

 

In addition to individual tungsten mines that don’t recycle valuable associated elements, the majority of tungsten mines recycle valuable associated elements comprehensively to varying degrees, of which the main metal recovered are molybdenum, tin, bismuth, copper, lead, zinc silver. But the level of comprehensive utilization of resources is uneven, due to technical limitations, economy, technology, equipments and other restrictions, the overall recovery of associated metals is not high. As Pangushan, Dajishan and Fenyi Zhujiang concentrators are focused on the comprehensive recycle of molybdenum and bismuth. The bismuth recovery is 60%; the molybdenum recovery is 45% in Pangushan Concentrator. The bismuth recovery is 53%; the molybdenum recovery is 78% in Dajishan concentrator. The bismuth recovery is 30%; the molybdenum recovery is 50% in Fenyi Zhujiang concentrator.
