Tungsten Metallurgy

Nearly all alloy steels containing tungsten are made in the electric furnace where tungsten is introduced to the steel’s metallurgy in the form of ferro-tungsten. Ferro-tungsten, melts between 3500 and 3700 degrees F., while tungsten powder melts between 6000 and 6200 degrees F. Neither will actually melt in a steel-making furnace, but the ferro-alloy because … Read more

Extracting Tungsten from Wolframite Gold Ore

The present great demand for tungsten due to world conditions has resulted in an increase of tungsten ore dressing problems for our metallurgists. The flowsheet study shown here was recently developed for treatment of a very complex tungsten-gold ore. The flowsheet study previously shown for tungsten was devised for a simple tungsten ore free of … Read more
