The well established two stage sequential flotation process is employed: Because most of the iron sulphides also report to the lead flotation tails and so feeds the zinc flotation circuit, typically lime is used to raise pH for iron sulphide depression. A lower molecular weight xanthate such as sodium isopropyl xanthate (SIPX) is used
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 non-valuable
An optimal laboratory two-step procedure was developed for sodium/potassium O-alkyl carbonodithioate (sodium/potassium alkyl xanthates) production in the form of aqueous solutions. Sodium isopropyl xanthate (Na-iPrX), as the most effective salt in a real ore flotation process, was also produced at an industrial level and introduced as a collector for copper ores.
2019-4-11 Xanthate, as the flotation collector with strong collection effect, is mainly used to enhance the hydrophobicity of the mineral surface to meet the requirements of flotation.Xanthate is commonly used in the flotation process of
2013-5-1 The solutions used containing sodium isopropyl xanthate were adjusted to the following concentrations: 6, 8, 10, 25 and 40 mg L −1. The results show that the three oxidation processes proved to be suitable for the destruction of xanthate, with the following maximum destruction efficiencies: 76% for electrolysis, 95% for UV photolysis and 99%
2021-9-21 Sodium isopropyl xanthate (Na-iPrX), as the most effective salt in a real ore flotation process, was also produced at an industrial level and introduced as a collector for copper ores.
2020-8-28 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 Cu–Pb 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.
2016-4-27 Flotation of Lead Ore. The flowsheet above was designed to treat economically approximately 200 tons in 24 hours of a low-grade dump ore
SIPX 90% 85% is a collector strong, selective non-ferrous metal sulfide ores better collector, widely used in copper, molybdenum, zinc sulfide flotation of auriferous iron ore flotation collectors better. For gold and copper-gold gold recovery rate has obvious advantages for refractory copper-lead oxide ore can obtain satisfactory results.
2017-11-22 The flotation of hemimorphite using the S(Ⅱ)–Pb(Ⅱ)–xanthate process, which includes sulfidization with sodium sulfide, activation by lead cations, and subsequent flotation with xanthate, was investigated. The flotation results indicated that hemimorphite floats when the S(Ⅱ)–Pb(Ⅱ)–xanthate process is used; a maximum recovery of approximately 90% was
Sodium Potassium and Zinc salts of Ethyl, IsoPropyl, nPropyl, IsoButyl, nButyl and Amyl Xanthates. Xanthates are used in the Froth Flotation for Extraction and Purification of Ferrous / Non Ferrous and Precious / Semi Precious Metals. Froth Flotation is a process for selectively separating hydrophobic materials from hydrophilic.
Sodium isopropyl xanthate and sodium n-butyl trithiocarbonate are used for the flotation of lead. An ore flotation process comprising: To a ball mill was charged 1300 grams of a lead/zinc-containing ore from Hecla Star mine along with 560 milliliters water and the slurry ground for 10 minutes 45 seconds to a Tyler screen mesh size of 22

2016-2-28 So, applying the lead-copper separation technique is possible separate bismuth and copper too. There are several methods for lead-copper separation. But, perhaps, the more common is employing NaCN as depressant for chalcopyrite, and also use a collector for improving bismuth flotation. The collector can be sodium isopropyl xanthate (SIPX).
Sodium isopropyl xanthate and sodium n-butyl trithiocarbonate are used for the flotation of lead. In a yet further preferred embodiment of this invention the composition used in the ore flotation process contains in addition to the two compounds (a) and (b), which, as will be shown, act synergistically in certain ore flotation applications

2016-4-27 Flotation of Lead Ore. The flowsheet above was designed to treat economically approximately 200 tons in 24 hours of a low-grade dump ore containing lead and zinc values as well as some silver in both sulphide and oxide form. Due to varying specific gravities of the values, gravity concentration in addition to flotation was indicated.
2021-9-21 Sodium isopropyl xanthate (Na-iPrX), as the most effective salt in a real ore flotation process, was also produced at an industrial level and introduced as a collector for copper ores.
The flotation reagents were used exactly in similar concentrations and in the same way as applied in the industrial lead-zinc flotation plants. sodium isopropyl xanthate, on the soil bacterial
