subjected to flotation in a bank of 25 and 28 litres flotation cells. All the reagents were added in the conditioning stage, except caustic soda (NaOH) which was added during the grinding stage as pH regulator. The conditioned pulp was subject to two roughing stage flotations and one cleaning stage flotation
There are 171 copper flotation chemical reagent suppliers, mainly located in Asia. The top supplying countries are China (Mainland), Turkey, and Pakistan, which supply 98%, 1%, and 1% of copper flotation chemical reagent respectively. Copper flotation chemical reagent products are most popular in South America, Africa, and Oceania.
Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed by froth flotation. Without froth flotation, many of the metals and minerals used every day in our modern world would be much more expensive. Solvent Extraction Solvent extraction is a hydrometallurgical process. The process entails

PDF Copper is most commonly present in the earths crust as copper iron sulphide and copper sulphide minerals, for example, chalcopyrite (CuFeS2), bornite (Cu5FeS4) and chalcocite (Cu2S).
Our flotation reagents are widely used for copper, lead, nickel polymetallic sulfide ore, non sulfide ore and precious minerals like gold and silver, aiming to help miners improve their flotation process as well as raise uselful minerals' recovery rate. Up to now, we have served both at home and abroad, with products exported to many countries.
Copper Flotation Reagents. Lime is usually added to the ball mill feed by a Dry Reagent Feeder. The frother and promoter are added in the classifier prior to flotation to realize the full effect of the reagent. Reagents can also be stage added to the cells in the flotation circuit.
In the copper, lead, and zinc industries the primary uses for cyanides are as depressants for the flotation of iron and zinc minerals and for the reactiva tion of copper minerals in the flotation of molybdenite.
flotation tailings and can be readily recovered by flotation with different flotation reagents. When amyl xanthate is used, 85% of chalcopyrite can be recovered with a copper grade of 14.5% in a single stage froth flotation. The chalcopyrite flotation concentrate can be sent back to chloride leaching circuits.
Dalian Shangfeng Flotation Reagents Co., Ltd As one of the leading flotation collectors, flotation frothers, flotation modifier reagents, pine oil, sodium amyl xanthate manufacturers and suppliers in China, we warmly welcome you to wholesale bulk chemical products in stock here from our factory. Quality products and low price are available.
Used as the flotation collector for non ferrous metal complex sulphide ore with medium selectivity and strong flotation ability, which is suitable for polymetalic sulphide ore consisting copper, lead zinc and so on. In the natural loop, it is particularly effective in the flotation for various copper and pyrite.

Flotation Reagents. Ninety two per cent is usually used for light pine oils, 27 per cent for a saturated solution of copper sulphate and 14 per cent for TT mixture (thiocarbanilide dissolved in orthotoluidine). The other percentages are for solutions of other frequently used reagents such as xanthates, cyanide
Furthermore, iron hydroxy species were formed on the pyrite surface, rendering it hydrophilic, thus preventing the formation of bubble pyrite particle aggregates. Key words pyrite, flotation, sulphite, depressants INTRODUCTION Froth flotation is widely used for separating sulphide minerals in
Flotation of copper or zinc sulphides by depression of the iron sulphides in selective flotation or in separation of bulk copper pyrite or zinc pyrite concentrates is realized as usual in alkaline environment created by lime (Abramov, 1983). However, the maximum recovery of
The reagents used in iron ore flotation, including starch, amines and fatty acids, and the mechanisms of their interactions with the minerals in iron ore are examined. The presence of some specific impurities other than quartz in iron ore, such as alumina containing minerals, i.e. kaolinite and gibbsite, and phosphorous, is detrimental and attracts penalties.
The pyrite grade in the fresh tailing sample and in the flotation product was determined indirectly from the content sulfur, copper and iron. Calculations carried out considering the elemental chemical composition presented in Table 1 and the mineralogical species that contained sulfur, identified by the XRD analysis, allowed to determine that the fresh tailings sample contained 4.56% FeS 2 and 0.75% CuFeS 2 .

Nokes reagent (thiophosphorus or thioarsenic compounds), or even cyanides, are widely used to depress the copper sulde minerals while molybdenum suldes are oated . However, many problems in the application are inevitable, such as the high dosage and toxicity to the environment.
DETA is a polyamine used as a depressant for pyrrhotite and arsenides in copper and nickel mineral flotation. Triethylenetetramine (TETA) Higher ethyleneamines, such as TETA can also be used as a depressant for pyrrhotite and arsenides in copper and nickel mineral flotation.
The efficiency of PIONERA BioPolymer versus sodium cyanide in copper recovery. Flotation results indicate that PIONERA BioPolymers, at each dosage, significantly reduce pyrite than conventional pyrite depressants. Additionally, conventional pyrite depressants such as sodium cyanide, sodium hydro sulfide and Nokes reagent are toxic, highly regulated, difficult to handle and present an overall costly alternative.
Copper sulphide ores Flotation collectors Mineral processing Alkyl hydroxamates abstract Sherwood Coppers Minto Mine processes a high grade coppergold deposit in Yukon, Canada. The ore mined is from a primary copper sulphide deposit with separate additional deposits of copper oxides.
The conditioning time was 2 10 min and the froth was collected for 5 25 min. In all tests a scavenging flotation was conducted and scavenger concentrate was mixed along with rougher concentrate. The rougher concentrates were reground and two cleaning flotation operations were carried out with addition of flotation reagents.
There are 321 reagents for copper flotation suppliers, mainly located in Asia. The top supplying countries are China (Mainland), Turkey, and Pakistan, which supply 99%, 1%, and 1% of reagents for copper flotation respectively. Reagents for copper flotation products are most popular in South America, Domestic Market, and Southeast Asia.
