  • Leaching Characteristics Of Upgraded Copper Flotation

    URRENTLY there is a drop in the copper ore grades around the world. The reclaiming of tails from old metallurgical extraction processes has been identified as key to the lifespan extensions of mines. Recent advances in the development and improvement of the processing techniques of low-grade copper flotation tailings are done so as to slow

  • Estimation Of Copper And Molybdenum Grades And Recoveries

    Jul 28 2016 After flotation stages a concentrate was produced with an average grade of 28 - 30 copper and 0.7 - 0.8 molybdenum. From the previous experience some factors that have an important role in the flotation of copper ore were selected as the

  • Froth Flotation Circuit Design And Basic Testwork

    Most flotation circuits include an initial stage of rougher flotation followed by a scavenger stage of flotation. The objective of passing through the rougher and scavenger flotation circuits is to maximise recovery of the desired minerals into relatively low grade concentrates that may typically contain 5-15 weight percent of the ore feed .

  • Mineral Flotation International Mining

    Nov 01 2011 As most copper orebodies exhibit an in-situ grade of less than 1 Cu the mass pull to the rougher froth is often low. This means that the throughput of the cleaner stage is significantly less than the throughput of the rougher stage which imparts a relatively low capital and operating cost to the flotation

  • Copper Recovery From Silicatecontaining Lowgrade

    93.1 and the grade of copper improved to 18.2 mass from 0.4 mass under collector-less opti-mum flotation conditions. The enrichment ratio of copper in the concentrate was 45. The copper concentrate obtained from flotation of the low-grade copper ore was treated by atmospheric leaching and high-pressure oxidative leaching processes.

  • Finncobalt Reports Succesfull Flotation Testwork Results

    Deleterious element grades in the concentrates were low. The average arsenic contents in the cleaner nickel concentrates were about 0.05 0.06 and 0.03 in the final copper concentrate. The sulphur grade in the rougher flotation tails was low about 0.4 which means that potential for acid mine drainage is very low.

  • Chapter9 Froth Flotation And Its

    The flotation method of concentration used extensively for other metal ores has only recently been utilized for hematite iron ores. It can be applied as either the sole concentration process or as a final concentration stage to ensure a high-grade product. In the flotation process air is bubbled through a suspension of fine iron ore in water

  • Goldprecious Metals Keynote Publications

    The main approaches considered to treat copper-gold ores or gold ores containing copper are 1. Flotation to generate a copper concentrate containing gold as a coproduct - and cyanidation of the flotation tail andor other concentrate streams to recover additional gold. 2. Cyanidation of selectively mined ore having low soluble copper. 3.

    The average grade is 0.7-0.75 copper and 0.022-0.026 molybdenum. The circuit tonnage is 34000 TMday the ore typically being upgraded to obtain a concentrate of about 30 copper and 0.8 molybdenum.The flotation circuit was recently modified by substituting two cleaner stages of mechanical cells by a single cleaner stage consisting of two .

  • Recent Studies On The Application Of Eriez Flotation

    Flotation recovery higher than 80 was achieved for sphalerite particles up to 1 mm versus 40 recovery achieved using a conventional mechanically agitated cell. Excellent recovery of both liberated and composite particles was also achieved during experiments using the HydroFloat to treat a coarse fraction of a typical copper ore.

  • Batch Flotation Test For Ore Charatcerization

    According to the mass balance results Wightman 2010 the copper recovery in Cu Rougher concentrate is about 72 i.e. 28 of copper is lost to pyrite flotation circuit. The test results given in Figure 3.15 on the other hand showed that 5 gt extra collector addition to Cu Rougher Tail will increase the recovery in copper rougher section .
