Precipitateflotation of fluoridecontaining wastewater from a semiconductor manufacturer was investigated. The process involves the addition of calcium chloride to generate precipitate and the subsequent removal of calcium fluoride (CaF 2).Results from dispersed air flotation (DiAF) experiments indicate that through the adjustment of molar ratio of calcium and fluoride ([Ca 2+]/[F −]) and ...
Jan 01, 2018· Heavy Liquid Separation indicated that conventional preconcentration of the drill core samples from both deposits would result in unacceptably high fluorite CaF2 losses. At a maximum CaF2 loss to floats of 5% the benefit of DMS would be economically marginal and difficult to justify as a conventional preconcentrator.
