2011-11-1 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.

2005-6-1 In this work, rougher flotation of low grade copper minerals (0.6–0.7% Cu) was tested in column cells at laboratory scale. A negative bias regime was used in order to create a levitating effect on particle–bubble aggregates to promote gross particle flotation.

2019-12-15 Copper sulfide ore samples from the southern region of Chile are used in rougher froth flotation and kinetics tests conducted at a laboratory scale. The samples are free of chemical reagents (collectors, frothers, and modifiers) and possess a 50% pass particle size (D 50) between 80 and 90 μm. The samples contained minerals such as chalcopyrite (1.80%), covellite (0.11%), molybdenite

2020-6-16 A study to determine methods to hinder the flotation of pyrite, other than the specific use of lime, in rougher flotation was conducted. Specifically, the goal was to determine an effective alternative to pH adjustment using lime. Experiments were conducted using the most common selection of reagents: xanthate and lime to recover

2021-1-20 The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents:

2015-6-22 It is usual to prepare the pulp for flotation by adding the reagents to the grinding circuit or in a conditioning tank ahead of the flotation section, but soluble frothers such as pine oil and quick-acting promoters such as the xanthates can be added at the head of the machine if desired, since the air-lift provides enough agitation to emulsify and distribute them throughout the pulp.

The use of mixtures of collectors has long been recognised in plant practice and has been shown to enhance flotation performance. These benefits have been reported for a wide range of collector mixtures (anionic, cationic and non-ionic) and include lower dosage requirements, improved selectivity and rates and extents of recovery and an increase in the recovery of coarse particles.

The rougher flotation behaviour of Potash ore from the Potash Corporation of Saskatchewan was evaluated in both laboratory batch and continuous cells by the use of experimental designs. Data obtained in all tests were adjusted statistically and then used to estimate the parameters of proposed kinetic models. By means of statistical and physical significance criteria, the Beta distribution ...

2016-9-26 Abstract: The reagent addition control level of stibium rougher flotation has a significant impact on the performance of cleaner and scavenger flotation. Currently, due to the complexity of the froth flotation process, the addition rates of reagents, which are controlled by operators, are often not regulated properly in time.

In rougher flotation tests, biosolids show to be the most efficient non-CCs, achieving Cu recoveries of 64.1%. CC achieved 76.2% Cu recoveries while none of the pure biosolids main components achieved Cu recoveries over 60%. In the kinetics studies, only the partial replacement of CC (by 50% of Humic Acids (HAs) or biosolids) allowed a similar ...
