    · Influence of grinding on flotation of copper sulphide ores is investigated by tests in laboratory • Milling procedure affects concentrations of Cu and Fe in the pulp and flotation results • The effect of grinding condition on the flotation result is oredependent • Hypothesis for the test results based on mineralogy, pulp chemistry and mineral surface property Abstract It is well· The objective of copper flotation is typically to maximize the dollar return on the concentrate produced while minimizing the energy and other consumables It is also essential to minimize the nonproductive time that the process units are meeting production targets The economic efficiency is maximized by manipulating the grinding and flotation circuits along the grade/recovery curveGrinding and Flotation Optimization Using Operational· The present work initially studies the kinetics of microwaveassisted grinding and flotation in a porphyry copper deposit The kinetics tests were carried out on the untreated and microwave irradiated samples by varying the exposure time from 15150 sec Optical microscopy, energydispersive Xray spectroscopy and scanning electron microscopy were used for determining the mineralEffect of microwave pretreatment on grinding and flotation

  • Increased liberation and flotation performance of bulk

    On the other side, copper selective flotation of the reground bulk concentrate was realized to evaluate the anticipated metallurgical improvement Process parameters such as involvement of prior hydrocycloning and variation of collector dosage have been evaluated Within a 2minute residence time inside the RoStar mill, an improved liberation degree of the copper bearing minerals has beendifficult due to several interactions that occur at the mineral surfaces during the processes of grinding and conditioning Flotation of copper sulphides is a traditional technique for processing the sulphide copper The presence of pyrite in copper concentrates (especially the pyrite particles that are surrounded with the chalcopyrite) is the most important problem of copper ore processingA study on the effect of active pyrite on flotation ofcomplex mixture of copper sulphide and small amount of copper oxide minerals However, a number of flotation parameters have not been optimized to meet concentrate standards and grind size is one of the parameter The purpose of this research project was to analyze the effect of grind size on concentrate production at a mining company in Zambia The researcher set objectives which were toAnalysis of the Effects of Grind Size on Production of
