Classification of tungsten ores-Metalpedia - Asian Metal
Classification of tungsten ores; Tungsten ores; Tungsten does not occur naturally in its pure metallic state; rather, it is found in several ores, but only two kinds of tungsten-bearing mineral rocks, called wolframite and scheelite, are mined commercially. Wolframite accounts for about 70% of the total tungsten resources in the world, and scheelite accounts for about 30%.

Tungsten Metallurgy - Mineral Processing & Metallurgy
This is a typical flowsheet for a tungsten ore containing an important amount of gold associated with sulphide. The Mineral Jig recovers a high grade tungsten-gold product which is amalgamated and cleaned up in a batch through a Unit Cell for gold and sulfide removal. "Sub-A" flotation removes the balance of the gold bearing sulfides.

tungsten and gold bearing ores
The primary goal of this investigation was to demonstrate tungsten and gold recovery from scheelite-bearing gold ores. In Alaska, at least seven gold-tungsten deposits have been identified. One of these deposits, the Big Hurrah, is well defined, and deposits of its type may, in aggregate, contain significant resources of both tungsten and gold.
