Kinetics and mechanism of natural wolframite interactions

Abstract. The kinetics and mechanism of natural wolframite interactions with sodium carbonate during air heating were studied. X-ray phase and X-ray microanalysis were used to establish that the initial monocrystalline wolframite consists of Fe 0.5 Mn 0.5 WO 4 and Fe 0.3 Mn 0.7 WO 4.Differential thermal analysis showed that the interaction of wolframite with sodium carbonate begins above 450 Get price

Concentrates

Concentrates. Marketable ore concentrates of scheelite and wolframite (hbnerite, ferberite) contain typically 65 – 70 % WO 3.Off-grade concentrates having lower WO 3 concentrations are seldom on the market and if so, only for a lower price. In fully integrated companies lower grades (6-40% WO 3) are often preferred, because upgrading to high concentrations is mostly combined with a lower Get price

Tungsten Concentrate

Tungsten has the highest melting point of all the metallic elements and a density comparable to that or uranium or gold and about 1.7 times that of lead. Tungsten alloys are often used to make filaments and targets of x-ray tubes. It is found in the minerals scheelite (CaWO 4) and wolframite [(Fe,Mn)WO 4]. Get price
