Abstract
The invention relates to an improved flotation cell design for the mining industry. The flotation cell includes a cylindrical froth flotation unit and a unique hexagonal overflow froth launder. The unique design optimizes the froth flotation process and allows for the economical utilization of a honeycomb nesting arrangement.
Claims8
A froth flotation machine comprising:
- (a) at least one upright cylindrical flotation cell having an upper end;
- (b) an inlet box attached to said cell,
- (c) a discharge box attached to said cell;
- (d) a rotation mechanism means contained in said cell for producing a mineral rich froth;
- and
- (e) an hexagonally shaped overflow froth launder mounted to and circumferentially extending about the entire periphery of said upper end of said flotation cell for collection of said mineral rich froth.
An improved flotation machine including an array of at least two rows of cylindrical flotation cells, an inlet port in the cell at one end of each row of cells for feeding into said end cell finely divided mineral ore and a fluid, a discharge port in the cell at the opposite end of the row of cells for removal of unseparated fluid and ore from said cell an aeration means located in each cell for creating a mineral-rich froth therein, a hexagonal shaped overflow froth launder provided on each of aid cells for collection of said mineral-rich froth, said hexagonal shaped overflow launders of a first row of cells contacting the hexagonal overflow launders of an adjacent row of cells in a honeycomb configuration.
A flotation machine comprising an array of at least two rows of cylindrical flotation cells, each of said cells provided with a hexagonal overflow froth launder, the hexagonal launders in one of said rows contacting the hexagonal launders of an adjacent row in a honeycomb configuration, each of said cells having an inlet means, an outlet means, and aeration means located in each of said cylindrical cells.
