  • pH/ORP measurement Copper flotation process

    pH/ORP measurement Copper flotation process Mining separating minerals by flotation Measurement made easy Introduction The flotation process can separate a required mineral such as copper nickel molybdenum or zinc from ore Flotation can separate this mineral from waste materials or from another mineral The process starts with crushed ore A ball mill receives the crushed ore and

  • Effect of pH on Copper Flotation Recovery VS Mass Pull

    An example of testing the effect of pH on rougher flotation on pit samples and the results are presented Since this is only an example it needs reminding that not all ores will respond the same Here rougher flotation is most Selective at a pH of 95 as pH levels in the 9 to 10 range yielded 1% to 2% better recoveries Mineralogy data also supports this and shows between 3% and 10% of the

  • The Importance of pH in Flotation

    In flotation pH control is a vital method to control selective mineral separation A standard depressant that is used is an Alkali An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE This is very important The ore may be either alkaline or Acidic To have a positive control over flotation it is necessary to be

  • Copper Flotation Elmhurst College

    The copper minerals and waste rock are separated at the mill using froth flotation The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and groundup limestone) to give a basic pH pine oil (yes it comes from trees a byproduct of paper mills) to make bubbles an alcohol to strengthen the bubbles and a

  • LowerpH Copper Flotation Reagent System Department

    A new reagent system developed by Versitech Inc with assistance from DOE's Inventions and Innovation Program recovers copper minerals at a much lower pH than conventional reagents and avoids floating pyrite The process reduces or even eliminates both the lime used in copper flotation and the accompanying carbon dioxide The result is
