The Direct Flotation Reactor (DFR) is a flotation cell that works on the principle of preventing the formation of a froth and froth slurry interface. Independent bubbles are removed from the collection zone in a gas phase/slurry phase.
Gold Recovery Equipment; Flotation Machines; ... analysis points out that for general applicability and particularly in view of the increasing trend to coarser flotation feeds, the larger cells now inevitable must be designed and operated: (a) with optimum coarse particle suspension as the dominant design criterion; (b) with provision for ...
to the feed compared to a conventional mechanical flotation cell. The design and operating conditions of the reactor is believed to promote hydrodynamic cavitation (Sobhy and Tao, 2013) and the formation of ultrafine bubbles on particle surfaces, which aids the agglomeration of fines and hence their subsequent recovery as effectively larger ...

Gold losses during flotation often occur within the fines fraction, which has been an ongoing issue that has challenged the gold mining industry. Subsequently, operations will attempt to coarsen up the primary grind to reduce the fine gold (free gold or sulphide gold) generation, resulting from over grinding. Under-grinding can then to lead to gold losses …
