Tungsten Oxide

Wolframite and scheelite mixed tungsten ore flotation is a worldwide difficult problem, because of the black and white tungsten composition structure is very different, conventional flotation method at room temperature and heating method is not ideal. Would there have a more effective way to realize whether black and white tungsten mixed flotation? Chairman MAO once said: “There is a way, it just hasn’t been found.” He also said: “Paths are made by men.” And actually it does. After many years of industry practice, our country's scholars found that the focus on black and white tungsten study is mixed flotation collector, the flotation is strong while the collector is strong, scholars use the collector as the breakthrough point, make many light avenues. In 70s and 90s, Chinese scholars use 731 + 733 combination of black and white mixed tungsten ore flotation collector, 731 and 733 to mix ratio of 10:1, the collector has the advantage of source is easy to obtain, the dis...

Wolframite and scheelite are different with the same name, there are all “w” but their body structure are not the same, so their beneficiation method is different, black tungsten gravity commonly used the separation method, scheelite commonly used flotation process. After years of development, our country each has a solid industrial foundation of beneficiation technology in wolframite and scheelite tungsten ore flotation. From a single scheelite recovery of scheelite in bed or recovery of wolframite from single black tungsten deposit is relatively easy. But why there is a certain type of skarn deposits made mistake like, they try to make the black and white tungsten together under the same roof, so the deposit is called "black and white mixed tungsten deposit. Mixed black and white tungsten ore flotation is a worldwide difficult problem, in this type of ore deposits, the black and white tungsten are in fine grained disseminated separately symbiosis in the strata, alth...
