Does flotation rely on the physical or chemical property of the ore

Aug 10, 2015 Flotation relies on differences in surface properties of different minerals to achieve separation. The study of these surface properties is known as surface chemistry. In flotation, it is necessary to understand the surface properties of minerals. Most importantly, surfaces can be either hydrophilic (water loving), or hydrophobic (water fearing)

    Froth Flotation Process - Detailed Explanation With

    Froth flotation is an important concentration process that can be used to selectively separate hydrophobic materials from hydrophilic waste gangue. In a more simple context, froth flotation is one of the most popular operational processes for mineral beneficiation. In ore/mineral beneficiation, froth flotation is a method by which commercially

    There, we mix the ore with an aqueous solution and grind it into a fine powder. We then mix the ore powder with water, chemicals and air in flotation cells. This process causes the copper-bearing minerals to stick to air bubbles in the cells. When the bubbles float off the top, we collect them as a liquid concentrate that is 28 percent copper
