ReWoRK – Recycling Tungsten from Ore Concentration
Tungsten recovery from dump material. For a long time, tungsten ores such as scheelite have been processed exclusively by technological processes involving a considerable amount of unused material. This led to the accumulation and storage of immense amounts of finegrained residues of processing material, socalled tailings.
TUNGSTEN Indian Minerals Yearbook 2018
The total reserves/resources of tungsten ore in the country, as per NMI data, as on 1.04.2015 based on UNFC system, has been estimated at 87.39 million tonnes with WO 3 content of 1,42,094 tonnes. All these resources are placed under ''Remaining Resources'' egory. Resources of tungstenbearing minerals are mainly distributed in Karnataka (42%),
Tungsten Minerals Eduion Coalition
Tungsten is retrieved from the ore minerals scheelite (CaWO4, calcium tungstate) and wolframite ((Fe,Mn)WO4, ironmanganese tungstate). A significant amount of tungsten is recovered through recycling of scrap tungsten products. Uses. Tungsten is mixed with carbon to make a very strong, very resistant material called tungsten carbide.
