The first publications and investigation reports on mineral processing, as well as the metallurgical treatment of processing products of lead vanadate ores and rich lead vanadate ores, were published between and [53,54,55]. The ores were considered as a potential source of vanadium for the rapidly increasing steel : Ivan Silin, Klaus M.

Hahn, Devrim Gürsel, Dario Kremer, Lars Gronen, Srećko Stopić, Bernd Friedrich. The tailings can contain as much as 50 pct of the CO originally present in the mined ore. Researchers at the U.S. Bureau of Mines have successfully tested on a continuous basis a process that recovers a bulk sulfide concentrate from mill by: 3.

A method for recovering scheelite by froth flotation from a slimey low grade tungsten ore pulp containing calcareous minerals other than scheelite, such as calcite, apatite or fluorite, and siliceous gangue which comprises agitating said ore pulp at a strongly alkaline pH for at least 5 minutes with an energy input of at least 25 hp.
