scheelite

1.The major metal minerals recycled include tantalum niobite, fine spar, tantalum aeschynite, wolframite and scheelite, which have large density of generally 5 to 7.

主要回收的金属物钽铁、细晶石、钽易解石、黑、白，密度比较大，一般为5~7。

2.Under hygrothermal climate, a series of physicochemical changes take place on huebnerite-scheelite deposit,containing polymetallic sulphi-des and slich a deposit forms a secondary tungsten deposit.

在温湿气候条件下，含多金属硫物的锰-白床会产主一系列的物、变，形成次生富集床。
