- Ore Concentrating Table Flotation Cell Fine Pricing Good Quality
Agitated flotation cells are widely used in the mineral processing industry for separating, recovering, and concentrating valuable particulate material from undesired gangue. Their performance is lowered, however, when part of the particulate system consists of fines, with particle diameters typically in the range from 30 to 100 μm.

Froth flotation column is a type of flotation device used for the separation and concentration of minerals from ore slurries. Unlike conventional flotation cells, which operate with mechanical agitation to generate air bubbles and mix the slurry, flotation columns utilize a tall vertical vessel with a continuous flow of water and air.

The Cu/Ni sulfide ore for bench-scale flotation was from the Yanbian Copper–nickel Mine. The results of chemical analysis of the ore are listed in Table 2.It showed that the main composition of the ore for bench-scale flotation is as follows: 27.81% MgO, 38.91% SiO 2, 12.38% Fe 2 O 3 and 6.02% CaO, which only contained 0.20% Cu, …

A laboratory Hydrofloat cell with a diameter of 6-inches was used for the coarse flotation of the Platreef ore. The experiments were conducted in batch mode with 10 kg of the dry basis of material, pulped at 77% solid pulp density, and conditioned in an 88 L rotating drum to prepare the feed for the HF testwork.
