Recent Performance of Copper-Zinc Flotation at Mikobata Mill

Multichannel reflectance spectral assaying of zinc and copper flotation slurries

Vitrification of copper flotation waste.

The vitrification of an hazardous iron-rich waste (W), arising from slag flotation of copper production, was studied. Two glasses, containing 30wt% W were melted for 30min at 1400 degrees C. The first batch, labeled WSZ, was obtained by mixing W, blast furnace slag (S) and zeolite tuff (Z), whereas the second, labeled WG, was prepared by mixing W, glass cullet (G), sand and limestone. The glass...

Studies of the Mechanism of Rock Mineral Flotation at Clarabelle Mill

At the Clarabelle mill, significant amounts of rock minerals float inadvertently during nickel and copper sulfide flotation, causing poor concentrate grades. It is known that the rock minerals that report to the concentrates are amphiboles and phyllosilicates. However, the latter are found only on concentrates obtained by processing highly altered ores. The amphiboles, which occur as both prima...

Comparison between Helical and Elliptical Static Mixers Performance in Column Flotation of Sungun Copper Plant

The flotation circuit in Sungun copper plant consists of two column flotation cells as cleaner, having fixed-spargers system. To achieve the expected aims in flotation step, there are serious operational challenges such as: fast choking of the static mixers, boiling problem, burping phenomena and pulp overflow to concentrate lander, maintenance and control problems. An attempt was exerted by im...
