  Minerals | Free Full-Text | Flotation and Tailing Discarding of Copper ...

  2021930 · The mineral composition of copper–cobalt ores is more complex than that of copper sulfides, and it is also difficult to discard tailing efficiently in primary flotation for the fine-grained disseminated of ore. In this work, a mineral liberation analyzer (MLA) was employed to study the characteristics of minerals. As a significant mineralogical …

  2009827 · 1 Froth Flotation – Fundamental Principles. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and removed, while ...

  A Review of Recent Advances in Depression …

  2015416 · To achieve this copper/lead separation, bulk flotation is performed with depressants to control sphalerite and pyrite. Cyanide was used in the bulk rougher as it will also be used in the reverse. Rougher testing indicated that 10 to 50 g/tonne cyanide in the bulk rougher was sufficient. The bulk concentrate was then subjected to relatively high ...

  Selective flotation separation of copper-zinc-sulfur bulk …

  Abstract: The application of mixture flotation process after rough grinding ores of fine-grained embedded copper-zinc sulfides has advantages of high recovery and low cost. However, the bulk concentrate needs urgently to be processed for a highly efficient and complete separation of copper, zinc and sulphur concentrates.

  60 Centuries of Copper: The Flotation Process

  2024626 · In the case of copper minerals, the particles adhere to this froth, which is separated, whereas the great bulk of the useless material sinks to the bottom of the tanks. By varying the chemical conditions within the cells different results can be obtained, thereby making flotation highly selective in skilled hands.

  Use of Ozone in the Differential Flotation of Bulk Copper …

  Differential flotation of bulk sulfide concentrates from Duluth gabbro into copper and nickel concentrates could be implemented by first destroying the hydrophobic coating with ozone and then by recovering the copper concentrate with a copper-selective collector. A number of parameters involved in the use of ozone, such as the sequence and the conditioning …
