23 23 Copper winning with Sulfidic Ore Crushing & Conveying Primary Crushed Ore Copper Concentrate Grinding & Flotation Smelting & Refining

24 24 Flotation Los Pelambres Concentrator

25 25 Flotation Grinding (Ball mills are used to grind the ore particles down to 0,22 mm average particle size) Flotation Cells

26 26 Flotation Cell Fine particles will be mixed with water by the addition of a surfactant or collector chemical. Activation of minerals to be recovered The slurry will be aerated to produce bubbles Activated mineral particles attach to the air bubbles which rise to surface. The froth with a higher mineral content will be removed. Repeating of the procedure with the aim to reach a concentrate with 20-30% copper content TAKRAF DELKOR BQR Flotation Cell
