Study on Optimization of Tungsten Ore Flotation Wastewater

A large amount of collectors, inhibitors and modifiers such as oleic acid, water glass and sodium carbonate are added to the flotation processing of tungsten ore, resulting in the difficulty of the suspended solids (SS) with the residual water glass settling down in the flotation wastewater. The removal efficiency of the suspended solids is low The comminution process and flotation beneficiation of Pb–Zn polymetallic ores require water supply flows of about 6000 L/h (Jennett & Wixson 2005). As evidenced by the change in the proportion of solids arising in the pulp during the ore processing beneficiation (Fig. 2 ), most of the feedwater from the ore flotation (80–90%) Review of Practices in the Managements of Mineral Wastes

Minerals Free Full-Text Beneficiation and Purification of Tungsten

Pb–BHA complexes have been shown to be selective for the separation of tungsten and cassiterite minerals from calcium minerals. These minerals could be enriched synchronously to some extent using Pb–BHA complexes flotation. However, it is difficult to further improve the quality and recovery of the scheelite, wolframite, and cassiterite As a strategic rare metal, tungsten is widely used in high-performance metallic materials like cemented carbide. The wet decomposition of scheelite CaWO 4 and wolframite (Fe,Mn)WO 4 is the primary and important step in tungsten metallurgy. According to the phase separation behaviors of the decomposition products, the wet Understanding the wet decomposition processes of tungsten ore:

Tungsten Metallurgy SpringerLink

Tungsten metallurgy is the technology that extracts the tungsten metal from tungsten ore raw materials. In 1781, the Swedish chemist C.W. Scheele separated a new oxide from scheelite and named it tungstic acid. In 1783, the Spanish chemists J.J. Elhuyar and F. Elhuyar, who were brothers, separated tungstic acid from wolframite.In this paper, beneficiation studies were carried out on a low-grade tungsten-bearing scheelite from Nezam Abad ore with total WO3 grade of 0.11%. Mineralogical studies showed that scheelite is mainly distributed in the ore and gangue minerals include Quartz and Tourmaline.
