    froth flotation of copper pyrites

  • The role of copper sulphate in pyrite flotation

    ThreePhase Froth Tests Table 3 shows the effect which copper sulphate had on the maximum froth height obtained in threephase froth studies. The standard deviation was obtained from a minimum of five tests for each case. The pH for all tests was 4 except Copper sulphate in pyrite flotation 209 for runs 4 12 and 13 which were done at pH of 9.

  • Extraction of copper from copper pyrites (CuFeS2

    Copper is extracted from its principal ore copper pyrites (CuFeS 2). The ore is concentrated by froth flotation process. The concentrated ore is roasted in a reverberatory furnace when the following reactions occur. 1. The volatiles like sulphur and arsenic escape as gases S + O 2> SO 2 4AS + 3O 2>2AS 2 O 3 2.

  • Clay and pyrite in copper concentrate VS frother Froth

    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.

  • (PDF) Pyrite Flotation: A Review ResearchGate

    Pyrite Flotation: A Review. Sulfide minerals are semiconductors and pyrite is the major gangue mineral associated with these ores. Main interest in the processing of complex sulfide ores has focused on the rejection of pyrite and selectivity problem that arises owing to the similar electrochemical behavior of pyrite to the other sulfide minerals in...

  • Pyrite Flotation Froth Flotation (Sulphide Oxide

    Pyrite Flotation (6 replies) 3. The effectiveness of activator (e.g. copper sulphate) can be affected by the pulp chemistry such as pH and Eh. Therefore it is important to monitor the pulp chemistry when you testing. 4. Froth stability could also be important and can be influenced by the collector dosage and also the addition of activator.
