We then mix the ore powder with water, chemicals and air inflotation cells. This process causes the copper-bearing minerals to stick to air bubbles in thecells. When the bubblesfloatoff the top, we collect them as a liquid concentrate that is 28 percent copper. The concentrate travels 17 miles toKennecott…

Flotation. The milled ore/gangue powder is mixed with a liquid and aerated in theflotationstep. The less dense ore rises in the froth to be collected, while the gangue sinks to be discarded. Flotation separates the metallic minerals from the gangue this way and – in the case of copper/ molybdenum ores – separates molybdenite from copper sulphide.
KrautFlotation Machine. The four-bladed impeller of the two preceding machines is replaced in the KrautCellby a rotor in the form of a helical screw revolving in a stationary upright cylinder. The construction of a2-cell unitis illustrated in Fig. 36.
The performance of frothflotation cellsis affected by changes in unit load, feed quality,flotationreagent dosages, and thecelloperating parameters of pulp level and aeration rates. In order to assure that theflotation cellsare operating at maximum efficiency, theflotationreagent dosages should be adjusted after every change in feed rate or quality.

FlotationFrothers What is the Function of Frothers. The function of frothers inflotationis that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.
Ninety-seven 3,000-cubic-foot-capacityflotationmachines replaced 2,000 old, smallerflotation cells. Engineers then phased out the original rail system that hauled concentrate to the smelter in favor of a new 17-mile-long slurry pipeline. When full mining operations resumed in 1988, per-pound production costs fell by more than 33 percent.

Savona Equipment is aflotation cellsupplier worldwide. Frothflotationis a process for selectively separating hydrophobic materials from hydrophobic. This is used in several processing industries. Historically this was first used in the mining industry. Frothflotationimproved the recovery of valuable minerals, such as copper- and lead-bearing minerals.
Columnflotation cellsare used in roughing and cleaning duties on a number of mines treating gold ores (Lane and Dunne, 1987). A columncelltypically provides higher concentrate grades compared to a mechanically agitatedcell; however, losses of coarse gold may be higher in the columncell( …
