froth floatation process of sulphide ore

Copper Mining and Extraction: Sulfide Ores, Stage 2: Froth flotation The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent It is then fed into a bath of water containing a foaming agent which produces a kind of bubble bath This is a rare chance to see a mill and flotation building before the roof is built (Courtesy of Codelco)Evaluation of flotation process course on the example of ,, The effectiveness was measured through the obtained values of concentrate recovery, concentrate grade, as well as tails grade 2 Scope of investigations The aim of the paper was to test and determine optimal parameters of flotation process course, for sulphide copper oreFroth Floatation Process, Froth Floatation Process , This results in the agitation of water in tank, which cause the sulphide ore particles to stick with the oil and rise to the surface in the form of froth The gangue particles being heavier remain behind at the bottom of water tank The froth is separated and concentrated sulphide ore is obtained from it.
