This was the first application of flotation without the aid of oil. In 1904 A. P. S. Macquisten invented a tube apparatus in which surface tension is utilized for concentration. In 1906 the process was applied on a working scale in the Adelaide plant at Golconda, Nevada, where chalcopyrite was separated from a lime-garnet gangue.
The beneficiation flowsheet at Bernic Lake involved dense media separation, pre-flotation of amblygonite, magnetic separation and flotation as illustrated in Fig. 10. The feed size to the dense media separator was −12 + 0.5 mm in which a mixture of ferrosilicon and magnetite with media density of 2.7 was used as a media.

This installation was one of the first large plants to prove the value of flotation in the treatment of gold ores. At the outset, when the ore to be milled was mined at or near the surface, 80% of the values were recoverable by amalgamation, and a 90% recovery could be made by a simple amalgamation and table concentration process. ...
It is known that the flotation separation of fluorite/calcite is extremely difficult because of their similar surface features. In this research, the combination of FeSO 4 ·7H 2 O and Fe 2 (SO 4) 3 (FF) as depressant for possible flotation separation of calcite/fluorite was systematically investigated, with sodium oleate (NaOL) as collector. Besides large …
1. Introduction. Historically, the dominant beneficiation strategy to recover cassiterite (SnO 2) from tin ores has been gravity separation (including jigs, spirals and tables), which could be followed by sulfide flotation for further upgrading (Bulatovic, 2010).As gravity concentration techniques are very sensitive to particle size, the …

1. Crushing stage: jaw crusher, hammer crusher. The 0-150mm material enters the 200*300 jaw crusher through the trough feeder, the crushed material is transported to the hopper through the belt conveyor, and feed to the 600*800 hammer crusher by the electromagnetic vibrating feeder for secondary crushing.
1. Introduction. The importance of flotation, as a separation process, to the economy of the whole industrial world is considered to be enormous. Without this process, many familiar metals and inorganic raw materials would be exceedingly scarce and costly because the high-grade ores that could be processed by simple physical and …
