Siderite Beneficiation with Magnetic Separation-Flotation Combined Method

Abstract:

Exploratory experiments were conducted according to the property of a siderite mineral composition and structure has the advantages of simple structure, low grade theory. The siderite Contain Fe 27.46%, Pb 0.97%. First magnetic Fe separation, because of the lower grade ore, for the two stages selection, In 90% of the fineness, good beneficiation indexes, Fe concentrate grade reaches 45.49%, the recovery reached 96.21%. The Fe tailings of magnetic separation in the 90% fineness of flotation tailings Pb test, The tailings in without further grinding conditions, after two stages of cleaning grade is still difficult to improve, Pb concentrate grade of 2.64%, recovery reached 46.96%, Observed in the tests of carbon in tailings interference, because well floatability of carbon, and the dissemination too small it is difficult to remove, so lead to difficulty for improving the grade of the lead concentrate.
