Mining Process Of Copper As Flash

Mar 21 2019 the copper mountain mine is in the process of expanding to include the new ingerbelle project photo courtesy copper mountain mine canada is one of the worlds major copper producers with the highest concentration of the metal being sourced in ontario and bc most companies mine copper as a coproduct in conjunction with other metals

For copper oxide ore electrowinning is the final stage in the process of hydrometallurgy in which concentrated copper solution from the heap leaching and solvent extraction processes is used as an electrolyte an electric current is applied through an inert anode resulting in the plating of copper onto 999 pure copper cathodes

Copper production technology the last boomin technological innovation for the copper industry occurred in the first two decades of this century whenopen pit mining flo tation concentrationand the reverberatory smelter were adapted to porphyry copper ores with the exception of leachingsolvent extractionelectrowinning the basic methods

Flash smelting is a pyrometallurgical process for smelting metal sulphide concentrates it is used primarily for copper sulphide concentrates but it is also used to a significant extent for nickel sulphide concentrates the flash smelting process for sulphide concentrates was developed by the finnish mining company outokumpu oy from 1948

Modern copper smelters use processed copper ore fed into a flash furnace typically fired by oxygen which produces blister copper being further processed in a converter furnace molten copper is poured from here into rectangular moulds the resulting ingots subjected to electrolysis producing a metal of 999 purity copper can be recycled indefinitely without the base metal being compromised

Doe runs sweetwater mine and mine no 29 are located nearby so much is happening underground at any moment we often call our mines underground cities our metal mining operations in the viburnum trend contain some of the worlds purest lead we produce lead copper and zinc concentrates to sell around the globe

The pressure is not important for the process as such but is defined by the steam saturation pressure of the process at 240c the pressure is approximately 35 mpa the slurry is then cooled in a series of flash tanks to around 106c at atmospheric pressure and by flashing off steam this steam is used to preheat spent liquor

The oxygen flash furnace at the asarco copper smelter in hayden arizona the oxygen flash furnace is initially heated up with natural gas it becomes so hot that the copper concentrate immediately ignites when it is blown into the furnace along with oxygen and a silicabearing flux

Automation the complex industrial process has produced a large number of production data which contains rich information for the mining of their patterns in order to improve energy efficiency of the copper flash smelting process this paper presents a method for minimizing energy consumption with meeting three technical indexes

Figure 1 overview of copper production benefication process figure 2 overview of a typical beneficiation process at a concentrator sulfidic copper ores are too dilute for direct smelting smelting these materials would require too much energy and very large furnace capacities the copper ore coming from the mine 05 1

Because pains were taken to control the amount of copper deposited throughout the process a typical total of only 2 to 3m of copper is removed in the flash etch this minimal copper etching preserves the profile of the circuit traces permitting the production of finer lines figure 13 figure 13 trace profile after msap processing

Autoclave using steam from the flash vessels this considerably reduces the heating of incoming solution as well as reducing exhaust gas flash vessels decrease the pressure and temperature of slurry that comes from the autoclave in a controlled manner proper sizing of the flash vessel is essential to ensure smooth operation of the process and

Gold ore prominer maintains a team of senior gold processing engineers with expertise and global experience these gold professionals are specifically in gold processing through various beneficiation technologies for gold ore of different characteristics such as flotation cyanide leaching gravity separation etc to achieve the processing plant of optimal and costefficient process designs

Processes copper mining and production copper is found in natural ore deposits around the world this page explains copper mining the production route taken from orecontaining rock to a final product that is the highestpurity commercial metal in existence and used in a wide variety of applications essential to modern living

Based on process the copper smelting market can be divided into reverberatory smelting oxygen flash smelting acid plant tappingtheflash furnace converter furnace and others reverberatory smelting and oxygen flash smelting are methods that require the resultant molten copper to be further processed to attain 999 pure copper

Table 1 water use in the copper industry in arizona and texas 1951 188 2 unit use of water in the mining of copper ore 1955 190 3 previously published data showing unit use of water in the con centration of copper ores principally by watergravity sepa ration and flotation 192 4

This is an interactive activity that allows students to explore the processes involved in the mining and processing of copper ore and the production of copper students initially place the processes in correct sequence and can then select each stage to animate it and access relevant information

Flash converting closely resembles flash smelting above all it is a closed process and consequently offgas emissions can be efficiently controlled flash converting had its first application in the expansion and modernization of kennecotts copper smelter near

At olympic dam the concentrate is flashsmelted directly to blister copper in this process copper concentrate is fed into the smelter with oxygenenriched air the fine concentrate reacts or flashes instantaneously as the sulfur fraction of the copper sulfides is burnt and becomes sulfur dioxide gas

Feb 03 2011 the novel flash ironmaking process conceived by sohn 52 at the university of utah is based on the gaseous reduction of iron oxide concentrates in a flash reactor it takes advantage of the large specific area of fine particles of iron ore concentrate much like the flash smelting of copper or nickel sulfide concentrate
