It is closely related to agriculture... [29,30]. Fatty acid is a common collector of oxide ore. It is widely used in the flotation of calcium- containing minerals such as scheelite, apatite, fluorite and calcite [31-34]. The ability of fatty......
-hosting granodiorite in the Wudaogou scheelite deposit were carried out. The results show that w(206Pb)/w(238U) ages of zircons from the granodiorite range from 264 to 269 Ma and have a weighted mean age... the same trace element composition, which indicates that the ore-hosting monzogranite is metallogenic intrusion. However, compositions of trace elements in scheelite minerals from Wudaogou scheelite......
