ore pulp rougher flotation

A cascaded recognition method for copper rougher flotation

Jan 16, 2018· Fig. 1 shows the rougher flotation in a certain copper flotation site. During the whole flotation process, rougher is the first step of screening after ore is ground, mixed with water and classified. The products from rougher include the rougher froth on top of the cell and the pulp flow at the bottom of the cell.

The Role of Coarse Conditioning Drums in Potash Flotation

The ore, now in the form of a pulp, is ready for conditioning. About Potash Coarse (Rougher) Conditioning. Also called reagentizing, conditioning is a critical step in potash froth flotation (and also in many other industries that use froth flotation, such as when liberating phosphates).

Xanthate decomposition in ore pulp under flotation

Jan 15, 2019· Compared to the SIBX decomposition rate constant of 0.128 h −1 at 70 °C in aqueous solutions (Shen et al., 2016), the average rate constant in the ore pulp is at least one order of magnitude smaller. This implies that the ore and the flotation conditions reduce SIBX decomposition and/or prevent CS 2 transfer out of the pulp.

Rougher flotation of copper sulphide ore using biosolids

Nov 01, 2011· Rougher flotation results for the concentration of a copper sulphide ore in a Denver cell with biosolids or a salt of humic acids as both collector and frother indicate that these materials have potential to substitute conventional chemical collectors and frothers used in the industrial flotation of sulphide minerals in Chile.

Parametric Optimization in Rougher Flotation Performance

Flotation experiments were conducted in a Denver type agitated flotation cell at the rougher stage. The experimental results showed that increasing the pH (from 8 to 10) at low agitation rate (1000 rpm) enhanced the recovery from 80.36% to 85.22%, while at high agitation rate (1200 rpm), a slight declination occurred in the recovery.

Impact of flotation hydrodynamics on the optimization of

The flotation beneficiation of phosphate ore is increasingly facing challenges, especially for finely disseminated sedimentary ores rich in carbonates. This study aims to optimize and assess the impact of key hydrodynamic parameters including pulp density, air flowrate and impeller speed on flotation and metallurgical responses (i.e. grade

INTERPRETATION OF FLOTATION DATA FOR THE DESIGN

Hellyer ore contains finely disseminated chalcopyrite, sphalerite, galena, and tetrahedrite. The flotation plant design was based on extensive benchscale testwork (including locked cycle tests) on drill core and many months of operation of a 30 tonne per hour “pilot plant” using the old Cleveland Tin Mine process plant, modified for the duty.

Effect of pulp potential on the flotation of a sulfide

These were sulfidization of the pulp prior toflotation and using nitrogen to replace air in flotation. Sulfidization requires pulp potential control to keep this parameter in the range of 0 to +100 mV, yielding high copper recoveries at minimum collector (90 git) and fr other (60 git) dosages.
