Potassium amyl xanthate is a collector with high collection and normal selectivity,widely use in floatation of Cu/Pb/Ne and pyrite,especially for the floatation of the gold in gold and copper could make good result in copper and lead oxidized used in rough selecting and scavenging.
Xanthate is the common name for chemical reagents used in the flotation of base and precious metals, which is the standard method for separating valuable minerals, such as gold, copper, lead or zinc minerals, from nonvaluable minerals, such as limestone or quartz (gangue).

#0183;#32;flotation with PAX Post by mekilcoyne #187; June 9th, 2013, 5:55 pm trying to find some PAX (potassium amyl xanthate) for some flotation experiments with some 65 100 micron flakes.
An increase in thiol chain length increases the maximum contact angle, thereby increasing the hydrophobicity of the surface species. Both these attributes favor the use of longerchain xanthates, such as potassium amyl xanthate (PAX), for the flotation of free gold.
PAX solutions are relatively stable if they are kept cool and the pH is maintained within an acceptable range. Under certain conditions, potassium amyl xanthate decomposes to very toxic and extremely flammable carbon disulfide. The rate of carbon disulfide generation from solution increases with temperature, pH below 8 (becoming rapid
Potassium amyl xanthate is one of the most powerful flotation collector widely used in mineral processing. It is relatively unselective, and has a strong tendency to float iron sulfides unless depressants are used. It is used as a good mining reagent for the flotation treatment of all sulfide minerals, Cu/Ni sulphide ore, zinc ores, as well as gold
Find out about the science and chemistry of Potassium Amyl Xanthate (PAX, Xanthate is the common name for chemical reagents used in the flotation of base and precious metals, which is the standard method for separating valuable minerals, such as gold, copper, lead or zinc minerals, from nonvaluable minerals, such as limestone or quartz
Flotation reagents . Application : Potassium isoamyl xanthate is a most powerful collector of xanthate, widely used in flotation of sulfide ores, especially for the flotation treatment of CuNi compound sulfide ore as well as gold mine associate with pyrite. Remark
13/7/2020#0183;#32;Two reagent schemes were tested: a combination of potassium amyl xanthate (PAX) and a dithiophosphatebased (DTP) collector or a phosphinebased collector. Concentrate gold grades and recoveries in the cleaner stages ranged from 68 g/t to 331 g/t gold and 55% to 83%, respectively.

as a function of collector (potassium amyl xanthate, or PAX) addition. The first paper (McGrath et al., 2013) established the method used to study the behaviour and characterize the ultimate content of free gold recoverable by flash flotation. The knowledge gained from this research contributes to a better understanding of the impact of particle size,
Potassium amyl xanthate is one of the most powerful flotation collector widely Cu/Ni sulphide ore, zinc ores, as well as gold associated with pyrite( gold containing iron sulfides). This mining to create a collector with the selectivity of PEX and SIPX and the collecting power of Potassium amyl xanthate (PAX) . Feeding method: 10
#0183;#32;In this work, different flotationpreoxidationcyanidation methods are considered for treating a lowgrade refractory gold ore. On the one hand, the results of selective flotation show that 22% and % of total Sb and As, respectively, remained in the final tailings and only about 28% of the total Au remained for further cyanidation processes.
als. Similar rates of flotation for different tellurides were obtained when potassium amyl xanthate (PAX) was used as the collector [15]. It should be noted that the overall recovery of gold is not only determined by the collectors used, but also the modifiers ( lime) employed [16]. A classic example of an integrated tellurideflotation cir
Potassium Amyl Xanthate (PAX) Revised: May 2010 : MSDS Xanthate Solution Page 2 of 5 IMPORTANT NOTE REGARDING POSSIBLE PRESENCE OF CARBON DISULPHIDE (CS2) The freshly prepared xanthate solution will contain low levels of carbon disulphide. This is formed by decomposition of some xanthate molecules during dissolution of dry PAX.
1/12/2017#0183;#32;Potassium amyl xanthate (PAX) and sodium isobutyl xanthate (SIBX) are commonly used collectors in both the bulk and selective froth flotation of sulfide ores. These thiol xanthate collectors are conventionally mixed together as well as with more selective thiol collectors such as dithiophosphates (DTP) and dithiocarbamates (DTC), in order to improve selectivity.
copper flotation potassium butyl xanthate chemicals for gold. May 10, 2017#183; May 6, 2017 Flotation is the most common process applied in mineral separation flotation of sulfide minerals and some oxides, including copper, zinc, and lead oxide minerals. flotation; these xanthates include potassium amyl xanthate PAX, sodium isopropyl xanthate SIPX, and sodium isobutyl xanthate SIBX.
