  Copper Sulfide Flotation - 911 Metallurgist

  2016413 · The final cleaned flotation concentrate flows or is pumped to a Spiral Rake Thickener. A Adjustable Stroke Diaphragm Pump, mounted on the thickener superstructure, meters the thickened concentrate to the Disc Filter. The Thickeners are often used to store concentrates for filtration at fixed intervals.

  Flotation cells: Selecting the correct concentrate launder …

  2009111 · The selection of the size, number and type of flotation cells for a particular duty depends on two important factors. These are the required flotation residence time and the physical constraints of how much concentrate can be recovered for a given froth surface area and concentrate lip length. The residence time is influenced by ore type and ...

  Validation of predictive flotation models in blended ores for ...

  202271 · For the cleaner stage, a re-grinding of the concentrate was performed to reach a P80 value of 25–30 µm (with 4.33 Kg balls). Outotec-GTK laboratory flotation machine was used for flotation with 4-liter (rougher) and 2-liter (cleaner) flotation cells. 1800 rpm and an airflow rate of 3 l/min were used.

  Microwave roasting of flash flotation concentrate containing …

  202061 · The present study therefore investigated microwave roasting of coarse flash flotation concentrate containing carbonaceous matter, pyrite and arsenopyrite. The release of carbon, sulphur and arsenic was monitored, and the changes in preg-robbing behaviour of the concentrate were also investigated.
