At present, the coarse separation of scheelite is usually by gravity separation or flotation. Because scheelite is a kind of ore which is easy to be gravity-dressed, but because scheelite has fine dissemination size, it needs to be grinded to 0.2 mm before the basic monomer dissociation, thus increasing the difficulty of gravity recovery, and the recovery rate of gravity-dressing is low, the taste of scheelite in crude concentrate is not high.

A few days ago, the 2018 Summer Davos Forum and the 12th Summer Davos Forum were held in Tianjin. The theme of this forum is “Building an innovative society in the fourth industrial revolution”. The theme of this conference is mainly aimed at the issues of general concern to all parties, namely, how to continue to strengthen new kinetic energy in the current international environment, where the factors of instability and uncertainties have increased significantly, and the trend of anti-globalization has risen. And promote the sustained and steady growth of the world economy?

Environmental issues have followed the rapid development of the social economy. Nowadays, environmental issues have been put on the agenda as an important issue that cannot be avoided. Therefore, we must not only pursue economic development, but also go side by side with environmental protection! Therefore, the emergence of new environmentally-friendly materials will always become a topic after people have a meal. Although it is only a topic of time, it is not very shocking and will not detonate the audience. It just makes people feel inexplicable peace of mind! For example, the emergence of new environmentally friendly inorganic pigments, rare earth pigments, is still the focus of attention in the near future, because our new environmentally friendly rare earth pigments have been in line with international standards! And environmental protection is the eternal trend!

Tungsten has a very high melting point, very high strength, very small electron overflow work, and good chemical and chemical properties such as good chemical stability and high temperature conductivity. Therefore, tungsten has excellent properties in the electronics industry and aerospace technology. Application prospects, molten salt electrodeposition is a method for preparing high-quality metals, with its simple equipment composition and operation methods, as well as its good bonding ability and other advantages have been widely concerned.
