INVESTIGATION OF EFFECTIVE PARAMETERS FOR ,, The flotation pH in most of the plants is above 10 and most often over 11 The relatively high pH used in the operating plants is not designed to depress pyrite, but rather as a frother modifier In reality, the higher pH produces a stable froth with better carrying power than at a lower pH for the majority of porphyry copper- molybdenite orEffect of pH on the Recovery and Grade of Base Metal ,, generally hither with the pH regulators per ton of ore treated For example: the cost of lime in sulphide minerals flotation is roughly double the amount of the collector used, so the significant operation cost saving can be attained by proper selection of the pH regulators [1] Lime being the cheapest, is widely used to regulate pulppolyacrylates used in copper ore flotation, what ph is commonly used in copper ore flotation Ball Mill Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two Sulphidation Of Copper Oxide Ore For Flotation Sulphidation Of Copper Oxide Ore For Flotation Production capacity : 018 - 20m³/min Power: 11 - 15 kwFroth Flotation, Lime is often used in flotation to increase the alkalinity of the pulp An alkaline pH increases the volume of the froth (possibly increasing the rate at which mineral is recovered), and depresses pyrite Frothers such as pine oil and Dowfroth 250 are used to create a froth capable of ,Improve Copper Production by Controlling PH in Flotation ,, Rich copper concentrate is produced from crude copper sulfide ore by means of a flotation procedure that takes benefit from the physical and chemical properties of small copper ore allergens To optimize the production rate of copper, pH control is essential inside the flotation tanks.
