Titanium Magnetite

An experimental research on comprehensive recovery of iron and associated apatite from a low grade vanadiferous titanomagnetite ore with high phosphorus was carried out. The results showed that using the technological flowsheet of “low -intensity magnetic separation-flotation”, not only the magnetite can be effectively separated, but the associated apatite in the mineral resources can also be satisfactorily recovered. An iron concentrate with a TFe grade of 64.81% and iron recovery of 58.04% and a high-quality phosphorus concentrate of 33.50% P2O5 with a yield of 92.18% is obtained．

Test was made on separating iron from a ultra-low-grade vanadium titanium magnetite ore by a process of tailing discarding at a coarser size，staged grinding and staged low intensity magnetic separation. The results show that when the raw ore is treated by permanent dry magnetic separator with low intensity magnetic separation at 12～0 mm size，qualified tailings of about 20% yield can be discarded．The coarse concentrate is grounded in two stages. With the first stage grinding size being 45% -200 mesh and the second stage，75% -200 mesh，and then treated by two stage low intensity magnetic separation．As a result，an iron concentrate with a TFe grade of 65.80%and an iron recovery of 47.74%can be achieved．

Comprehensive Recovery

With the depletion of mineral resources, more attention is paid on the secondary resources to recover valuable metals. In this paper, a research is carried out to recover copper and iron from copper smelting slag by flotation and magnetic separation. The influence of grinding fineness and collectors on flotation of copper are investigated. A copper concentrate is obtained by flotation and an iron concentrate is obtained by magnetic separation in the closed circuit flowsheet. The copper concentrate contains 18.86% Cu with a recovery of 72.36%, and the iron concentrate contains 52.24% Fe with a recovery of 70.87%.
