Study on Technological Mineralogy Properties of a Tungsten Polymetallic Ore

China's tungsten mining history has been more than 100 years,with the tungsten resources increasingly depleted,the development and utilization of tungsten resources are facing various problems.The research on the mineralogy of tungsten ore process has important significance for rational development and utilization of tungsten ore resources,efficient and reasonable comprehensive recovery of tungsten ore resources.The investigation conducted a process mineralogy research of the tungsten polymetallic ore,including chemical composition,mineral composition,occurrence and dissemination characteristics of major mineral,ore texture and structure analysis and ore grindability research.This paper provides the basis for the design of multi-metal comprehensive recovery program of this ore.In the study,the recovery value of the ore is mainly WO3,Sn,Mo,Cu,which also contains a small amount of gold,the use of copper and gold can be considered comprehensive recovery in order to improve the value of copper concentrate;which tungsten,copper,molybdenum,bismuth,Tin is mainly in the form of black tungsten,copper sulfide,molybdenum ore,bismuth ore and tinite;due to black tungsten and chalcopyrite embedded close relationship between the dissociated black tungsten ore particles will have More with chalcopyrite inlay,therefore,re-election tungsten concentrate will contain more chalcopyrite,from the black tungsten ore fine embedded in the grain size,the ore to be grinding to 0.3mm below Can be more than 70% of the"clean" black tungsten ore dissociation;Xizhi embedded cloth more fine in the 0.3mm below,generally below 0.1mm;tin tin embedded in the grain size is uneven,from 0.2 mm to 0.001mm There are distributed,generally below 0.1mm;molybdenum is a coarse grain embedded cloth.
