Sulphidizing flotation of copper oxide ore four different commonly used depressants were adopted in order to investigate the effect of depressants on chalcopyrite index and to investigate their inhibition effects on chalcopyrite experimental results indicate that in the flotation system of natural ph of pulp mixed reagent ofMore Details
The copper minerals and waste rock are separated at the mill using froth flotation the copper ore slurry from the grinding mills is mixed with milk of lime simply water and groundup limestone to give a basic ph pine oil yes it comes from trees a byproduct of paper mills to make bubbles an alcohol to strengthen the bubbles and a collector chemical called potassium amyl xanthate or the potassiumMore Details
The response of many minerals to the flotation process is often dramatically affected by ph flotation circuits are often operated at a ph range of 75 to 115 the exact range at any given plant is optimized for the ore at that site lime is often used to raise the ph of the pulp and also reduce the flotation of iron pyrite particle sizeMore Details
4 xanthate used in galena froth flotation process the surface of galena is hydrophobic so its easy for flotation xanthate is the common collector for the flotation of galena when the ph is high the galena is easily floated by the ethyl xanthate the optimum ph for flotation is 78 which can usually be adjusted with sodium carbonateMore Details
Dec 20 2018 collectors collectors commonly used in the flotation process of gold and silver ores include xanthate black powder and butylammonium black powder kerosene and transformer oil can be used as auxiliary collectors oleic acid can also be used as a collector for goldcopper oxide oresMore Details
A new reagent system developed by versitech inc with assistance from does inventions and innovation program recovers copper minerals at a much lower ph than conventional reagents and avoids floating pyrite the process reduces or even eliminates both the lime used in copper flotation and the accompanying carbon dioxideMore Details
Abstractthis study investigated the effect of ph on the recovery and grade of the platinum group metals pgms and base metal sulphides from the ug2 ore of the bushveld complex this was achieved through running a series of test work in a denver flotation cell at varying ph 611 at constant reagent dosage the ug2 reef is characterized by twoMore Details
Dosage of collectors ph and dosage of activator na 2 s were examined results of flotation tests were unsuccessful in terms of both recovery and grade of concentrate product the highest copper recovery of concentrate was found as 6135 with 869 copper content the concentrate with highest copper grade ofMore Details
Dec 15 2019 coppersulfur symbiosis is found in common types of copper sulfide ore flotation of copper ores is used to separate copper minerals from other sulfide minerals such as pyrite and gangue minerals because pyrite and other sulfide minerals decrease the grade of the copper concentrate and interfere with the subsequent copper pyrometallurgy process the main difficulty in the flotationMore Details
Froth flotation of the ground pentlandite and chalcopyrite particles at ph 9 which separates them from the pyrrhotite and gangue rock particles in the ore this bulk concentrate is sometimes separated into individual copper and nickel concentrates by froth flotation of chalcopyrite from pentlandite at aMore Details
A copper flotation flowsheet because the copper in this type of ore usually assays only plus or minus 1 copper the porphyry copper operations must be relatively large in order to be commercial the flowsheet in this study illustrates a typical 3000 ton per day operationMore Details
The flotation ph in most of the plants is above 10 and most often over 11 the relatively high ph used in the operating plants is not designed to depress pyrite but rather as a frother modifier in reality the higher ph produces a stable froth with better carrying power than at a lower ph for the majority of porphyry copper molybdenite oresMore Details
For industrial sulfide mineral flotation the xanthates and dithiophosphates are the major classes of flotation collectors compounds used where m is either na or k and r is a relatively short hydrocarbon chain typically containing two to five carbon atoms the solubility ph application range physical state solid or liquid andMore Details
Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the differentMore Details
