  • Size dependent gold deportment in the products of copper

    Size dependent gold deportment in the products of copper flotation and methods to increase gold recovery by G. Small A. Michelmore and S. Grano* Synopsis Plant survey data has shown that gold recovery through a specific copper concentrator was significantly lower than copper recovery. Sizebysize analysis revealed that this was due to poor

  • Copper Flotation Mineral Processing Metallurgy

    Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs. Also considerable attention is paid to automatic sensing devices and automatic controls in order to assure maximum metallurgy and

  • Flotation Froth an overview ScienceDirect Topics

    Copper (or metal) recovery percentages of the flotation circuits of a copper mine/mill are extremely important. For example it is estimated that for a plant processing 50 000 tonnes of ore containing 1% copper per day increasing the copper recovery from 86 to 87% of that contained in the ore could increase revenues by approximately $4 million

  • Processing Gold Ore by Flotation

    A test on a sample crushed to pass a screen of 120 holes per linear inch containing $37 gold and 4.8% copper gave a recovery by flotation alone of 90% of the gold and 98.5% of the copper but left $8 gold in the tailing. The concentrate carried 44% insoluble matter which could be reduced by retreatment. A different oil (eucalyptus) would have given a poorer recovery and a cleaner concentrate.

  • Separation efficiency improvement of a low grade copper

    The recovery of goldcontaining pyrite to the copper concentrate is encouraged to achieve a higher total gold recovery provided that a saleable copper concentrate grade is still produced. Mineralogical diagnosis of feed and product streams from the copper flotation circuit have shown that the copper bearing minerals are well liberated

  • How to Process Copper Lead Zinc Ore with Gold and Silver

    The leadcopper concentrate also contains the major part of the gold and silver values present in the ore. The high gold recovery possible by a flowsheet of this type is augmented by the Mineral Jig which recovers the coarse free gold. The amalgamation residue which is high grade lead is combined with the leadcopper flotation concentrate in
