Metallurgical Content. Scheelite and Wolframite WO4) are the principal minerals of tungsten, but other important minerals include ferberite and huebnerite will also respond to froth flotation. The high specific gravity of these minerals makes many of these ores amenable to gravity concentration methods, however, the fine dissemination of mineral in gangue for some ores may require finer grinding and recovery of mineral by flotation at finer sizes.
beneficiation technology applicable to these deposits. The deposits covered are: Degana, comprising of four distinct types, namely, quartz vein, eluvial, phyllite and granite, Balda, Khobna Kuhi Agargoan, Burugubanda Tapaskonda, Scheelite bearing gold ores of Kolar and Hutti, and Madurai.
Scheelite is the easiest of the tungsten minerals to recover by flotation. Fatty acids or fatty acid soaps, such as oleic acid or sodium oleate with an alkaline dispersing agent such as sodium silicate, soda ash or caustic soda, are the common reagents which are used for scheelite.
Brief Introduction of Scheelite. Scheelite, also known as calcium tungsten, is one of the most important and common type of tungsten ore. 80% of the beneficiated scheelite is used for iron and steel smelting, another 15% of it is made into hard steel, and the remaining 5% is used in other places. In short, with the high value and wide range use, the tungsten promotes the development of industry.
The separation of scheelite and cassiterite can be carried out by electric separation or flotation. During flotation separation, scheelite is captured with fatty acids, and cassiterite is suppressed with water glass. When scheelite contains aluminum, because molybdenum has good floatability, molybdenum ore can be floated first, and then scheelite.
Wolframite and scheelite are main source minerals for tungsten extraction. In scheelite ores, especially in skarns, fluorite, apatite and calcite constitute common gangue minerals. Nowadays, the main route for scheelite beneficiation is the flotation .
Scheelite sorting method can re election, magnetic separation, flotation. Different types and nature of the ore beneficiation methods and processes used are different. But based on scheelite good floatability, more due to the presence in the ore of a similar nature to their gangue minerals calcium, which led to the flotation of complexity. Advantages
Froth flotation of scheelite has regained new focus since the 2010s and research regarding floatability and reagents has made great progress over the years. The main objective was and remains the selective flotation of scheelite from other calcium bearing minerals, in particular calcite, fluorite and apatite.
