In this work, the role of glucan in the flotation separation of pyrite and pyrophyllite was studied and the selective depression mechanism of glucan on pyrophyllite was discussed. The flotation tests indicate that pyrophyllite is a naturally hydrophobic mineral. Using glucan as a depressant can achieve flotation separation of pyrite from pyrophyllite at the natural pH of the pulp. This is attributed to greater

When corn starch was used as a depressant, flotation separation of the artificial mixedmineral samples and the bauxite ore were conducted by using BDDA as a collector at pH around 910.
#0183;#32;The flotation tests indicate that pyrophyllite is a naturally hydrophobic mineral. Using glucan as a depressant can achieve flotation separation of pyrite from pyrophyllite at the natural pH of the pulp. This is attributed to greater adsorption and stronger depression effect of
The flotation separation of pyrite from The effect of pH on the flotation recovery of pyrite and pyrophyllite using OGM/guar gum as depressant were studied by single mineral flotation tests and the results are shown in Fig. result in Fig. 3 shows that the flotation recovery of pyrite was very high (gt; 88%) in the pH range of 39, with increased in pH, pyrite recovery decreased due

The effect of cationic groups on performance of 12carbon chain collectors in flotation separation of diaspore from kaolinite, pyrophyllite and illite has been investigated by flotation tests and explained by density functional computations. The flotation test results indicated that the separation of diaspore from these aluminosilicate minerals was feasible at strong alkaline conditions by

#0183;#32;The flotation recovery of pyrite and pyrophyllite were about 87% and 20% respectively when the OGM dosage was 50 mg/L, indicating that the flotation separation of pyrite from pyrophyllite can be realized at an OGM dosage of 50 mg/L.

Tests were carried out in a Hallimond microflotation cell and a Denver D12 cell on typical residue material from a gold mine in the Orange Free State (South Africa), in which 50 per cent of the kerogen was larger than 100 JLm in size. Although kerogen is naturally hydrophobic, the observed unexpectedly poor flotation reponse may be due to occlusion of the kerogen by a slime coating and
#0183;#32;In this paper, the reverse flotation separation of diaspore from kaolinite, pyrophyllite and illite is investigated by flotation tests using dodecylamine chloride (DDAC), dodecyl trimethyl ammonium chloride (DTAC) and dodecylguanidine sulfate (DDGS) as collectors, and the flotation results are further explained from the structurereactivity relationship of collector by density functional computation at

flotation separation experiments of diaspore from bauxite ores was conducted in the presence of a Gemini cationic collector and the starch depressant. 2 Experimental Minerals and reagents Handpicked pure minerals of diaspore, illite and pyrophyllite were obtained from Mianchi Bauxites, Ohai Mine, Qingtian Mine in China. Kaolinite was obtained
The flotation separation of pyrite from pyrophyllite using oxidized guar gum (OGM) as depressant has been studied through flotation tests, adsorption and FTIR spectra measurements.

#0183;#32;It is possible to float uraninite selectively from some of the gangue minerals with which it occurs. Oleic acid was found to be an excellent collector, giving over 98% recovery and a very low assay rejectable tailing. With the standard synthetic ore mixture ground to 96% minus 100 mesh, pounds
