  • Effect of clay minerals on pulp rheology and the flotation

    Effect of clay minerals on pulp rheology The effect of Snobrite Q38 and bentonite on the pulp rheology of the clean ore in flotation was investigated. The rheograms of the clean ore suspensions indicating the shear stress as a function of shear rate with and without the addition of Snobrite Q38 and bentonite are shown in Fig. 2 Fig. 3 Fig. 4 respectively.

  • The effect of clay minerals on the process of flotation of

    The presence of clay leads to low recoveries in the process of flotation of copper ores which is also reflected in a decrease of the concentrates grades. Due to this the scientific interest in studying the effect and mechanisms of action of clay minerals in the flotation process has increased which has resulted in a better understanding of the physicochemical foundations behind.

  • Froth Flotation (Sulphide Oxide)

    However very often in porphyry copper flotation the frothing is generally controlled by pH. The presence of clay in the ore is the main reason for unstable froths and reduced frothing power. It has been demonstrated that destabilization of frother occurs in the presence of ultra fine particles thus the reduction in flotation may occur.

  • Depressants for Clay / Flotation depressants

    Clay depression. Clay depressant in a gold and copper bulk flotation plant trial In production at a Gold and Copper flotation circuit the use of PIONERA F100 showed a recovery increase in gold of 5% and a positive effect on the copper recovery by successfully depressing clay in the bulk flotation process.

  • Kaolin Flotation Beyond the Classical

    However the beneficiation of kaolin a naturally occurringfine ore via flotation has been practiced over the last 40years. Kaolin is valued as a white pigment and therefore the goal in kaolinflotation circuits is to remove the colored impurities to result in an acceptable brightness product.
