Magnetite and Hematite Ore Processing Methods

Magnetite-hematite ore dressing methods

1 single magnetite - hematite ore

Mainly hematite - magnetite and magnetite ore - siderite ore. Sorting methods such ores with weak magnetic re-election, flotation, high intensity magnetic separation joint, which uses a weak magnetic magnetite recovery with re-election, flotation recovery of weak or strong magnetic magnetic iron minerals magnetic roasting and magnetic separation or other methods of parallel processes, with a single weak magnetic iron ore magnetic roasting similar, but in the magnetic mineral roasting and magnetic separation methods in parallel with other processes, the powder ore is used in weak magnetic combined with other methods selective flocculation de-sludge method.

2 multi-metal-containing magnetite - hematite ore

Such ores are mainly: sulphide ore and phosphorus, sulfur, or rare-earth iron ore. Such iron ore beneficiation is the most complex, the general weak magnetic separation combined with other methods of process, which uses a weak magnetic recovery of magnetite; re-election, flotation recovery of weak or strong magnetic magnetic iron minerals and elements associated with the flotation recovery.

Magnetite-hematite ore crushing and grinding methods

As the difference of mining method and ore concentrator production capacity of transport conditions, blocks sent to the processing of the ore dressing plant are also different degrees, such as open-pit mining ore, bulk 1000 to 1500 mm; underground mining of ore, bulk of 300 to 600 mm. Under the current technical conditions and equipment performance, wishing such a crush large pieces of ore to the required size sorting is difficult. Industrial production in the mineral phases is breaking grinding stages. First to use large pieces of ore crushing machinery will break or a few millimeters to a few millimeters, then the use of grinding machines to grind the ore to the required size sorting.
