| titleOfInvention | A kind of stage grinding of microfine low-grade magnetite, stage grading new method |
| abstract | The invention discloses a kind of stage grindings of microfine low-grade magnetite, stage grading new method, secondary magnetic separation rough concentrate is fed into high frequency fine screen operation, magnetic separation under lower part of screen lease making is sieved sieves lower magnetic concentrate and feeds the selected operation of column magnetic separator, obtains column magnetic separator concentrateï¼›High frequency fine screen is sieved into upper part, the tailing of the selected operation of column magnetic separator feeds concentration magnetic separator and carries out concentration magnetic separation, acquisition concentration magnetic concentrateï¼›Concentration magnetic concentrate forms closed circuit through-three sections of ore grindings of three sections of pre-classifications, and overflow feeds magnetic separation three times, four magnetic separation, obtains four magnetic concentrates.Magnetic tailing, secondary magnetic tailing, concentration magnetic tailing are subjected to sieve classification processing, coarse grain tailing part is sold as building materials yellow sand substitute.The present invention has the advantage that iron concentrate grade is high, magnetic iron recovery is high, stable, easy to operation in production, and magnetic iron recovery is increased to 94.0% or more by only about 80%. |
