  • Preconcentration of Low-Grade Ta–Nb Deposit Using

    2021-3-29 · The concentration from gravity separation goes through the magnetic separation unit to obtain the columbite–tantalite concentrate.6 Gravity concentration is used as a roughing unit for preconcentration of high-density columbite–tantalite because of the benefits such as the larger tonnage units and low cost of some gravity concentration ...

  • Preconcentration of Low-Grade Ta-Nb Deposit Using

    Ore from the Jinzhulong Ta-Nb deposit was processed using a combination of gravity concentration and magnetic separation to upgrade the columbite-tantalite fines. Two flowsheets, namely for gravity concentration-magnetic separation (the conventional flowsheet) and magnetic separation-gravity concentration (the novel flowsheet), are proposed herein, and the factors
