  • Use of Cleaner Spiral equipment as Scavenger Spiral ...

    The design specifications for Rougher spiral, Cleaner spiral and Scavenger spiral are different from each others, like pitch, through angle and turns. Now, what we are feeling means, if we use Cleaner spiral as scavenger spiral these design parameters may not produce good yield and recover. Still we are in dilemma position.

  • Size recovery curves of minerals in industrial spirals for ...

    2014-10-15  The mineral size recovery curves show that the rougher spiral recovery of iron carrier particles finer than 0.075 mm is less than 50%. Recovery of the iron carrier minerals increases with particle size but then reaches a plateau below 100% or decreases for particles larger than 0.5 mm. The fall of the recovery of coarse silica mineral carriers ...

    The rougher spiral tails were sent to a LIMS Cobber for recovery of the remaining magnetite. The Cobber concentrate (12.9% of the feed) is then sent to a regrind mill for further liberation of the magnetite. The liberated magnetite is then sent to the two-stage cleaning LIMS to produce an iron rich magnetite concentrate of 70.0% Fe.

  • MT to Deliver Concentrator Upgrade Project for QIO

    The new gravity circuit will utilise WW6 spirals in a new circuit arrangement with Mineral Technologies upcurrent classifiers, which combine to dramatically reduce recirculating loads and minimize losses to the rougher spiral stage tailings. Additional recovery gains will be accomplished with the inclusion of a magnetic separation circuit to recover fine iron from the gravity circuit tailings.
