Selective flotation of scheelite from calcium minerals

The results of the batch flotation tests on mixtures of these minerals showed that the recovery of scheelite from scheelitesilicate mixtures (31% WO 3) with (NaPO 3) 6 or Na 4 P 2 O 7 increased by 20% as compared with sodium silicate and the WO 3 grade of the concentrate by 5%. At room temperature, the scheelitecalcium mineral mixtures could

Different Flotation Performance of Ultrafine Scheelite

Scheelite particles are brittle and easily overground in the grind process [].As a result, there are always a large number of microgranular slimes in the scheelite pulp, which weakens the flotation environment and leads to the loss of the valuable minerals [].Decreasing the size of flotation bubbles is regarded as an efficient way to recover the fine fractions [].

Laboratory Testing of Scheelite Flotation from Raw

Tungsten is an essential metal for the manufacture of special alloys, which is in constant demand due to the development of the industry. The recovery of scheelite from undeveloped tungsten ore in South Korea was investigated to improve the flotation performance for high grade and recovery of concentrate. To investigate the interaction between the flotation reagents and the minerals, the
