The influence of grinding chemistry on the flotation behaviour of sulphides minerals has been widely studied. However its influence on partially oxidised sulphide ores is not well documented.
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source local environmental regulations and other factors.
Copper/Molybdenum Ore. The figure above is a simplified flow sheet showing the basic steps involved in a copper mill producing the byproduct molybdenum. The crushed copper ore (containing for example 0.75 Cu and 0.015 Mo) is fed to the grinding circuit where water is added and the ore is
Copper Sulfide Flotation Reagents. Lime is added to the Ball Mill by a Cone Type Dry Reagent Feeder. Other reagents such as cyanide xanthate and a frother are fed and controlled by No. 12A Wet Reagent Feeders to the classifier and to the conditioner ahead of flotation. Copper Ore Grinding. Porphyry copper ores usually are medium to
Copper sulphide ores are normally f iner grained than porphyry copper ores and require finer . grinding yielded a copper recovery of over 97 and wet chrysocolla grinding yielded copper recove
sulfide ore grinding copper Apr 23 2011 · Copper Ore Types Sulfides versus Oxides Sulfide copper ores are the most profitable ores because they have high copper content and the copper can be more easily separated from the unwanted minerals It is important to note that sulfide ores are not as abundant as the oxide ores.
A typical copper ore contains between 0.5 and 2.0 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.
In the extraction of copper from its sulphide ore the metal is finally obtained by the reduction of cuprous oxide with (a) carbon monoxide (b) copper (I) sulphide (c) sulphur dioxide (d) iron (II) sulphide.
Taking advantage of the hydrophobicity of sulfide ores to repel water the target ores are separated into copper-rich portions and the remaining portions. The ground ore is mixed with water to form slurry which chemical reagents are added and then aerated to produce bubbles.
• Rocks are crushed in a series of crushers. Sulfide ores are further reduced through a wet grinding process that ensures a particle size suitable for the flotation process. Copper leaching. Sulfide ores and froth flotation. Sulfide ores are mixed with water and a surfacant creating a slurry.

Sulfide Ore any of several natural mineral formations consisting of metal sulfides. Metal selenides tellurides arsenides and antimonides are also classified among the sulfide ores. Sulfide ores are an important source for the production of Ni Co Cu Zn Pb Mo Bi Sb and Hg. They contain not only sulfides but also other minerals including
Copper Mining and Extraction Sulfide Ores. Share The world s largest copper ore deposits are found in Chile on the west coast of South America. This is due to the volcanic activity that is part of the process that created the Andes mountain chain. Stage 1 Crushing and grinding The ore from the mine contains about 2 copper. To get

Sulfide mining which is sometimes referred to as hard-rock mining is the process of extracting trace amounts of copper nickel and other metals from sulfide ores. When sulfide ore comes into contact with water or oxygen a chemical reaction occurs and produces sulfuric acid

Mined sulfide ores contain pentlandite pyrrhotite chalcopyrite and gangue rock. A high-grade nickel concentrate is produced from these ores by the following minerals-processing techniques (a) crushing and grinding the ores to liberate the nickel- and cobalt
Copper processingCopper processingOres Principal forms in which copper ores are found include native copper porphyry copper massive deposits and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form but more frequently it is mixed with other minerals some of which may have value themselves. The amount of
Copper processing is a complicated process that begins with mining of the ore (less than 1 copper) and ends with sheets of 99.99 pure copper called cathodes which will ultimately be made into products for everyday use.The most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different
Copper Ore Crushing Grinding Flotation. Previous Next. View Larger Image Crushing and Grinding The attraction of semi-autogenous grinding in copper operations is that they can accommodate ores that are hard or soft wet or dry sticky or otherwise. Flotation Study of Zinc Sulfide by Infrared Spectrophotometry.
In vat leaching oxide or oxidesulfide ores are crushed and then leached in large vats with prepared leach solutions. Following a rinsing cycle the leached residue is discarded or further treated by flotation to recover the sulfide copper minerals. Each of these methods has its advantages and disadvantages.
Sulfide ores are first put through a jaw or gyratory crusher to reduce the rocks to about 78 inches. This material is then fed to a secondary grinder that further reduces the size to about 12 inches. The next step is to feed the crushed ore into a wet grinding process in tumbling mills.
Mixed copper ores are treated through different processes depending on the degree of oxidation as well as the consumption of acid. With the availability of real-time technology that can reliably measure differences between oxide and sulphide minerals it is now possible to control a mixed copper ore
A wide variety of copper sulfide prices options are available to you such as electron grade industrial grade and medicine grade. There are 216 suppliers who sells copper sulfide prices on Alibaba mainly located in Asia. The top countries of supplier is China from which the percentage of copper sulfide prices supply is 100 respectively.
Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction Sulfide Ores (11–14) but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching
Grinding the crushed ore in rotating tumbling mills (<100 μm diameter). (0.5 ) copper sulfide ores. New facilities started in 2006 are expected to produce 180 000 tons/year of copper using acid curing agglomeration and bioleaching followed by -EW. Spence.
A potential explanation of the different response of primary and secondary copper sulfide minerals to bentonite is that bentonite particles may preferentially coat the chalcocite surface during grinding. The oxidation of copper sulfide minerals is an important aspect in mineral processing.

In this process copper ore is mined crushed ground concentrated smelted and refined. The mining crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it.
