Apparatus and method for froth flotation
This patent describes a method for the froth flotation separation of the components of a slurry having particulate matter therein which is to be separated and collected. It comprises: spraying an input slurry of particulate matter into a liquid contained in a flotation tank to create a froth on the liquid surface; removing the froth from the liquid surface by skimming means, the skimming means passing the froth over a discharge surface. The discharge surface having at least one raised ridge means disposed thereon for preventing the skimming means from contacting the portion of the discharge surface upon which the at least one raised ridge means is disposed and cooperating with the skimming means and discharge surface to separate excess liquid from the froth prior to the collection of the froth.
