Virtually all sulfide-type copper ores, including chalcocite cu 2 s, chalcopyrite cufes 2 and covellite cus, are treated by smelting.After crushing the ore to a fine powder, it is concentrated by froth flotation, which requires mixing the powdered ore with reagents that combine with the copper to make it hydrophobic.
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.
Fire-refined copper is adequate for noncritical applications such as water tubing, bar stock, or ingots for alloying.Copper intended for electrical uses, however, is produced by electrorefining or sometimes electrowinning techniques.Electrorefining process virtually all copper produced from ore receives an electrolytic treatment at some stage.
These 5 following estimates on flotation mills cover standard practice as used on base metal and non-metallic ores where the majority of values are recoverable by flotation, and where there is sufficient freed mineral in the ball mill discharge to warrant recovery by means of process equipment like either a unit flash flotation cell, a concentrating table, or a jig, in the ball mill-classifier.
Any piece of equipment which forms a part of a larger process is collectively known as process equipment.End-use industries such as mining, wastewater treatment, steam power generation, salt water disposal etc.Have elaborate steps and processes which use different types of equipment at each stage.Some of the commonly used process equipment include pumps, valves, vessels, filters, coolers.
Microelectronic engineering 3738 1997 97-103 101 fig.Very effective dual damascene pattern filling at 190 with 5 cooling step between tin and cu deposition.Chemical mechanical polishing cmp was used for copper patterning.For this process good adhesion between the thick copper film and tin was required.
Bonding with copper wire is not without challenges special equipment and different process parameters are required as copper wire is harder and is easily oxidised.Due to these properties of copper, obtaining an intimate contact between copper wire and bond pad can be difficult.
Equipment used in brazing operations is typically classified by the process heating method.Unlike welding, all brazing uses a filler material, frequently copperbrass, silver, or aluminum-silicon, to join two bases together.Torch brazing involves heating and flowing filler using a gas flame near the joint it represents the most common type of brazing in current use.
Copper interconnects are formed using a dual damascene process at the end of which cmp is used to remove excess copper and tatan adhesionbarrier layer.Colloidal silica, the most commonly used abrasive in copper cmp slurry, chemisorbs onto the copper oxide cu 2 o or cuo and copper hydroxide cuoh 2 formed through oxidation of copper by.
The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product.Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
