Material
Tabuaço Falcon pre-concentrate
The pre-concentrate produced from Tabuaço ball-mill product by centrifugal gravity separation on a Falcon Semi-Batch bowl: about 15 per cent of the feed by weight, carrying more than 70 per cent of the tungsten at an enrichment ratio above 4.5, with most calcium-bearing gangue and almost all of the fines rejected. A pre-concentrate intended as flotation feed, not a marketable tungsten concentrate.

EstablishedDownstream of the pre-concentrate: nothing measured. Flotation proposed, with an estimated sevenfold reduction in reagent consumption; no test performed.
The flotation stage that would turn the Tabuaço pre-concentrate into a tungsten concentrate was PROPOSED and NOT PERFORMED: the study states the pre-concentrate could directly undergo fatty-acid flotation and estimates a sevenfold reagent saving from doing so, but reports no flotation test, product, grade or recovery.
