potassium amyl xanthate PAX. However, the pH for the flotation was 9.0 and 9.5, respectively, for using HCNPHA or PAX as collector. Time-recovery plots were fit using the modified first order rate equation for flotation kinetics, namely, 12, ev , and flotation rate constant and the cumulative recovery at time infinite R, were computed.
Jun 15, 2020 Interestingly, flotation of mixed mineral of copper sulfide and arsenic-bearing copper minerals shows that enargite and tennantite exhibit a higher floatability compared to chalcopyrite and bornite after the oxidation treatment followed by the addition of potassium amyl xanthate PAX. These flotation results indicate a possibility for ...
Potassium Amyl Xanthate - Flotation Reagent. Potassium amyl xanthate is a strong collector. It is widely used in the flotation processes of nonferrous metallic minerals where a strong but a non-selective collector is desired. It is a good collector for the flotation of oxide minerals, eg. oxidized sulfide, copper
Amyl xanthate potassium is a selective collector strong ability weak collector, widely used copper, zinc, nickel and containing pyrite flotation of gold and copper deposits improve gold recovery mine has obvious advantages for refractory copperlead oxide ore can obtain satisfactory results.
The copper ore slurry from the grinding mills is mixed with milk of lime simply water and ground-up limestone to give a basic pH, pine oil yes, it comes from trees -- a by-product of paper mills to make bubbles, an alcohol to strengthen the bubbles, and a collector chemical called potassium amyl xanthate or the potassium salt of an alkyl ...
Aug 28, 2020 The experiments showed that the pH, potassium amyl xanthate and sodium silicate variation influence copper, lead and zinc recoveries. In the first step, recovery of CuPb sulfide reached 45.49 with grade of 15.96 for Cu and 61.65 with grade of 7.4 for Pb. In the third step, the recovery and grade of Cu enhanced to 88 and 18.3, respectively.
XANTHATE APPLICATION Potassium Amyl Xanthate, s trong, unselective collector , with 5 carbon molecules in its chain, is strong, unselective, and is ideal for sulfide gold operations where all sulfide minerals need to be recovered. It can be applied for the flotation of all types of sulfide minerals in combination with weaker xanthates.

In froth flotation, the adsorption of collector on mineral surface is critical for a successful flotation process. In present work, an atomic force microscopy AFM has been applied to study the adsorption of potassium amyl xanthate PAX on copper sulfides, i.e., chalcopyrite, chalcocite and bornite.
Jun 24, 2019 The recovery of copper in aqueous media by ion flotation in a laboratory flotation cell was carried out. Hydrodynamics and gas dispersion parameters were obtained. The results show that the increase of potassium amyl xanthate concentration above the stoichiometric amount considerably affects the efficiency of the separation of copper. In a stage of flotation with recirculation, recoveries

The high recovery of the acid soluble copper in this circuit is outstanding, particularly as the only collector used was of the xanthate family, that is, Potassium Amyl Xanthate, which, in a current conventional circuit, has but little collecting effect on the family of acid soluble minerals, unless such modifiers as sulphidizing agents are used.
A flotation process in which copper ores or copper converter slags are ground and firstly have added thereto benzotriazole or alkyl benzotriazole as an activator and secondly one or more collectors selected from the group consisting of xanthates, dithiophosphates, thiocarbamate esters, dithiocarbamates, mercaptans and dixanthogens and further, if desired, a promoter such as kerosene, light oil ...
The differential flotation between pentlandite and pyrrhotite of HCNPHA was compared by repeating the experiments with potassium amyl xanthate PAX. However, the pH for the flotation was 9.0 and 9.5, respectively, for using HCNPHA or PAX as collector.
