Exploring new ways to acquire niobium resources is essential to resolve niobium supply risks, due to the fact that, at present, 99% of niobium is controlled by only two countries. In the present work, a …

The main equipment used are spiral chute, shaking table, jig and so on. The reselection is often combined with the silver ore flotation process. Cyanide leaching methods is mainly used for silver sulfide minerals. In order to increase efficiency, gold and silver concentrates are selected and then cyanided on-site to produce gold and silver.

The vanadium‑titanium magnetite with 67% passing 0.074 mm was taken from Chaoyang city, Liaoning province, China. The chemical compositions of vanadium‑titanium magnetite ore are presented in Table 1, which were determined by chemical methods combined with X-ray fluoroscopy (XRF).The vanadium‑titanium …

In the tests, the effects of particle size, pH, collector types and their amount were tested. The results showed that efficient separation of titanium bearing minerals could be achieved by oleate flotation at around pH 5, after grinding the ore down to -180μm. Oleate provided results superior to sulphonates and succinamate.
