And its hydrophobic flotation characteristics would be compared with those of the single-functional- group collectors including octyl-hydroxamic acid (OHA) and S-allyl-O-ethyl xanthate ester (AEXE) via water contact angle (WCA) and micro-flotation experiments. 2 Experimental 2.1 Materials HAOODE, OHA and AEXE were prepared …

It was found that a 2:1 ratio at a total consumption of 400–450 g/t of OMC 199 and AERO 845 in the presence of WG (4–4.5 kg/t) and OrePrep F501 as frother (10–15 …

Alternative processes have been proposed for selective separation of fluorite and gangue minerals (carbonates and silicates) present in fluorspar ores. Calcination …

The flotation results showed that BDT had good flotation selectivity for chalcopyrite and galena, which achieved up to 96.67% and 50.26%, respectively, at pH 6 using a collector dosage of 100 g/t.

In this study, two new collectors for fluorite flotation DP-OMC-1033 (DP-I) and DP-OMC-1234 (DP-II) were tested and compared with oleic acid (OA), sodium oleate (SO) and potassium oleate (PO ...

This study aims to determine the flotation recoveries of smithsonite utilizing three novel collectors: sodium lauryl fatty acid amide, dodecyl hydroxamic acid, and 2-ethylhexyl phosphate, as well as the traditional collector, oleic acid. These reagents were examined at various temperatures, dosages, and pH levels using microflotation experiments.

The pH of pulp (5–11.5) and collector type in the flotation cell were changed according to the experimental requirements. In the lead flotation, certain amounts of depressants (zinc sulphate 400 ...

When adding Orica specialty collectors and frothers to the pulp, use microlitre syringes to add them neat. For flotation testing of 1kg of solid: 10 μL of neat solution = a dosage of …

1. Introduction. Thin liquid films are basic units of s and emulsions that are found in a wide range of industrial applications such as food, medicine, firefighting and froth flotation (Karakashev and Ivanova, 2010, Pugh, 2016).One way to study thin films is by generating a single horizontal film and analysing it using the interferometric method …

1. Introduction. Flotation collectors are amphiphilic molecules which adsorb selectively on desired mineral surfaces to improve their hydrophobicity (Gharai and Venugopal, 2016, Liu et al., 2017, Liu et al., 2018, Liu et al., 2020).High consumption and low selectivity of traditional collectors limit the processing of fine mineral particles from …
