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 …

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is …

About Wolframite Ore. Wolframite is a black or brown mineral which is the chief ore of tungsten. It consists of a tungstate of iron and manganese. The wolframite ore has a high depletion rate, low grade, coarse grain size, high density, low hardness, easy mud formation, and deep color, which is mainly extracted by the gravity separation process.
