The crushed copper ore (containing, for example, 075% Cu and 0015% Mo) is fed to the grinding circuit where water is added and the ore is ground to the proper size Lime and an oil for collecting molybdenum are usually added in the grinding circuit A copper collector may also be added at this point The pulp progresses to the flotation cells
A typical copper ore contains between 05% and 20% copper A high grade ore produces a high yield of metal A low grade order produces a low yield of metal Copper can be extracted from sulfide ores (usually higher grade ores) by direct smelting The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC

This flattened shape of the larger particles could be a contributing factor to the reduced flotation recovery at the coarser siz Optimisation of gold recovery by selective gold flotation 235 EXPERIMENTAL The gold bearing copper/pyrite ore from the Telfer Gold Mine was supplied by Newcrest Mining Ltd
Purposes: as collector copper, lead sulfide ore and gold, silver and other precious metals mineral flotation, commonly used in priority flotation separation of copper, lead and zinc sulfide ore sulfide ore Packaging: plastic bucket or pail, net weight 200kg / barrel Storage: Store in ventilated, sun warehouse Note: can be based on user needs technical indicators and packaging specifications
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilicThis is used in mineral processing, paper recycling and waste-water treatment industri Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century
RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan MS, Department of Mining Engineering Supervisor: Prof Dr Mustafa Ümit Atalay December 2014, 65 pages The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching
Effective flotation collector reagent selection is dependent on the sulphide minerals present, their mineral associations in the ore, and circuit characteristics Because an ore typically has more than one copper sulphide mineral type, often a combination of sulphide flotation collectors is used to maximize metallurgical performance
the ore and also lower floatability of pentlandite Copper recoveries were favored in AF208 and Mercaptan R247 due to the shorter chain length of the collector’s
According to the different flotability and floating speed among copper, lead, zinc ore, Xinhai separately obtains copper concentrate, lead concentrate and zinc concentrate from the slurry Application Simple mineral composition, large differences in flotability among useful minerals, coarse disseminated grain size, high-graded raw ore Advantages
About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine) These produce many millions of tonnes of copper ore per year The main ores of copper are sulfides and .
Copper extraction refers to the methods used to obtain copper from its or The conversion of copper consists of a series of physical and electrochemical process Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors
Only then are the copper minerals broken free of the rest of the rock to be separated by flotation Concentrating The slurry of water and pulverized ore is mixed with milk of lime to raise the pH and small amounts of special reagents: a frother to make bubbles, and a collector chemical that causes the copper minerals to stick to those bubbl
The preferred flotation is suitable for such ores as the content of copper is higher then nickel and as mineral symbiotic relation is not too complex The copper and the nickel concentrate can be got conveniently in the preferred flotation But for the nickel ore is seriously inhibited which leads to the low recovery rate of the nickle
Abstract: Based on the chemical analysis and mineral composition research, a series condition tests were done with ore grade 145%The optimum conditions were grinding fineness -0074mm65%, collector as butyl xanthate- Ammonium aerofloat butyl(3:1) with 100g/t ,activator as sodium sulfide 200g/t,foaming agent as 2#oil of magnetite 30g/t
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 useThe most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different .
1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry The particles with attached air ,

Simply said; a Flotation Collectors is a chemical used to make the surface of minerals, which is metallic, hydrophobic or in layman’s term ‘afraid of water’ or ‘water hating’ as others like to say This chemical used will behaved, in a way, as a wax would when you applied it to your car After wax (or hydrophobic agent) is adhered to the surface, that surface with see water pearl-away
