TECHNOLOGICAL POSSIBILITIES FOR PULP DENSITY ALTERATION AT ELATZITE FLOTATION MILL ... at 32 % pulp density for rougher flotation. The lab and industrial scale investigations performed have provided an opportunity to raise this parameter up to 42 % at a ... the increase in pulp density for copper rougher is leading to lower copper content in ...
A new highcapacity flotation technology, the StackCell, has been developed as an alternative to both conventional and column flotation machines. This technology makes use of a preaerated, highshear feed canister that provides efficient bubbleparticle contacting, thereby substantially shortening the residence time required for coal flotation.

An inherent limitation with the flotation of fine partcles in conventional cells is recovery of hydrophilic (gangue) particles by mechanical entrainment in the water reporting to the froth. The method of minimizing entrainment is to create a 53Ocm thick froth at the slurry surface. The froth permits the gangue to drain back to the pulp while
Particle size, reagent type and dosage, air flow rate, pulp density, and wash water rate are some of the influential parameters on flotation process efficiency [8, 28, 33, 34, 39]. Although copper flotation and the effect of key parameters and operational conditions have been studied previously [2,

2. 2. Flotation Procedure All the flotation testwork was done using the Denver laboratory machine with a stainless steel flotation cell. The required mass of nickelcopper sulphide ore material ground to 70% passing 75 µm was weighed and placed in the flotation cell. This was followed by the addition of distilled water to about

Finally, at the end of the flotation reduction was continued by grinding the product from the crusher time, concentrate with a grade of % copper, % Al2O3, and in a ball mill for eight minutes at a pulp density of 60 wt.% solids to % SiO2 was obtained.
One of the methods was based on acidic leaching of kaolinite from the flotation waste [10] which resulted with obtaining the kaolinitic concentrate containing 32% Al2O3. Other methods included vitrification of copper flotation waste [19], with possibility of .
