Mining and Processing . The magnetite ore which makes up a large percentage of the existing orebody is mined as part of the usual open cut mining process. Processing . Copper and gold are recovered from the ore using traditional grinding and flotation methods in the concentrator. Magnetite is liberated during this process and the magnetite
Dense media separation (DMS) is a gravity separation method in which a suspension material such as magnetite or ferrosilicon is used to form a medium denser than water in separation. This method is used to separate valuable materials from waste. Multotec supplies a complete range of DMS processing equipment, which includes a customisable and industry-proven range of …
ABSTRACT. In order to efficiently purify and recover the magnetite powder (dense medium) in the process of dry coal preparation of air-dense medium fluidized beds, a new type of fluidized dry magnetic separator was developed in this paper by changing the feeding device and mode, the location and structure of the separating tank, and the particles' movement direction …
