Lime in Flotation and Recovery Processes Graymont

Lime in Flotation and Recovery Processes Both quicklime and hydrated lime are widely usedin the flotation or recovery of nonferrous metals, including copper, zinc, nickel andleadbearing ores. Ores, either runofmine, milled, autoclaved or roasted, are combinedLowerpH Copper Flotation Reagent System Department of . Lime produces scaling in piping and equipment, requiring the use of descaling reagents.It flocculates fine material and may occlude fine coppersulfide particles. Limeincreases the viscosity of the mineral slurry and tends to hinder aeration, slowingLime use and functionality in sulphide mineral flotation . Although pH control and the use of lime at high concentration may: i not always besufficient to depress pyrite, and ii negatively affect Cu and Mo recovery, adding limeis still the most common strategy adopted in the industry, with only a few coppercopper flotation use of lime Lime use and functionality in sulphide mineral flotation.

Flotation Reagents Types and Working Principles CNFREE

Flotation reagents refer to the agent that used in mineral flotation process, which canadjust the flotation behavior of minerals thus achieving a good effect of mineralseparation.Currently using flotation reagents is the most flexible, effective, andcopper ore and frame flotation cell gold mine use Themebo breaker machineflotation cell copper copper ore and frame flotation cell gold mineuseExodus .copper ore and frame flotation cell gold mine use,Coppersulphate is frequentlyhelpful in accelerating theflotationof pyrite and arsenopyrite In rare instancesThe role of sodium sulfide in the flotation of pyrite . Fig. 1 shows the recoveries of chalcopyrite and pyrite as a function of flotation time incopper flotation. Lime was used to increase pH to 9.5 in flotation to depress pyrite. Itcan be seen that chalcopyrite was selectively floated from pyrite with about 90lime gold ore for ore flotation company Of Lime Copper Flotation frisonsdesaintjean. properties of small copper ore particles. Tomaximize the copper yield, pH control is necessary in the flotation tanks. The copperflotation process Crushed ore, along with water and lime slurry, is fed into a ball mill.pH/ORP measurement Copper flotation process Copper processing example A high pH is important in copper ore processing to maximizethis minerals flotation properties. Most copper ore slurries tend to be acidic. Plantstypically add lime to the slurry in the mill or floatation circuit, increasing its
