Flotation for Treating Sulphide Ores at a Coarser Grind Massimiliano Zanin1 Bellson Awatey1 and Jaisen Kohmuench2 1 University of South Australia 2 Eriez Flotation Division USA ABSTRACT Fluidisedbed flotation emerged in the last 15 years as a promising technology for the flotation of minerals at a much coarser particle size4850
The initial assessment usually involves grinding the ore sample drill core samples to various particle sizes and applying a reagent regime that is known to give the desired minerals separation Following a review of the initial flotation testwork results alterations are made to4780
generated during grinding At the end when the ore was heavily oxidised after 16 months of artificial oxidation all grinding media tested generated similar pulp chemistry and flotation performances of the ore suggesting that when sulphide minerals are strongly oxidised less galvanic interactions occur during grinding3438
grind size of copper minerals was determined as 75 microns after examination of ground particles under microscope During the flotation tests the effects of type and dosage of collectors pH and dosage of activator Na 2 S were examined Results of flotation tests were unsuccessful in terms of both recovery and grade of concentrate product3758
Phosphate ore is divided into siliceous phosphorite calcareous phosphorite and siliceous phosphorite according to the chemical composition of the mineralsThe froth flotation types differ from different types of phosphate ore greatly The following is a brief introduction to 5 common types of phosphate ore forth flotation process3900

Each ore is different and requires laboratory testing to evaluate the grind size slurry pH slurry density required reagents and retention time to maximise recovery of the desired minerals into a flotation4156
Nov 04 2016018332Low grades complex ores and rising energy costs have prompted the development of entirely new flotation vessels improvements to existing technology and new thinking about flotation flowsheets The frothfree flotation vessel comes by way of Eriez Flotation Division which patented it in 2002 and marketed it under the name HydroFloat4807
For sulfide ores on the other hand selective flotation normally follows the crushing and grinding stage and requires an optimal degree of liberation In the flotation process the finely ground ore mixed with water and special reagents is agitated by mechanical and pneumatic devices These produce air bubbles in the orewater mixture or3919

Aug 14 2017018332Grinding is done in closed circuit with classifier In many instances superior flotation is results are obtained by conditioning the ore with the reagents before the flotation step Oily type collectors are sometimes added to the grinding circuit to ensure dispersion Flotation machines are built in multiple units4837
Grinding is a subprocess of finely grinding ore in advance such that the ground output can be physically separated into iron ore and impurities in the downstream subprocess In many cases an Flotation separation is a technique utilizing the difference in the hydrophilicity of ore surfaces4479
