1 the process of preparing commercially pure red cuprous oxide from oxidic copper compounds selected from the group consisting of cupric oxide and mixtures of cupric and cuprous oxides having a total reducing power below about 95 that of cuprous oxide which comprises adjusting the total reducing power of the starting material to a level between about 95 and 105 that of cuprous oxide ... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
Through this process ammonium hydroxide was recovered using an evaporating device and copper hydroxide was transformed into cupric oxide The purity of copper in the oxide compound reached 9826 The economic evaluation of this process for a capacity of six tons of coppercontaining wastewater sludge per day is discussedGet Price

The smelter for sulfide ores produces sulfur dioxide gas This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores Scrubbing sulfur dioxide also protects the environment A byproduct of the smelting and converting furnaces is sulfuric acidGet Price
Some supergene sulfide deposits can be leached using a bacterial oxidation heap leach process to oxidize the sulfides to sulfuric acid which also allows for simultaneous leaching with sulfuric acid to produce a copper sulfate solution As with oxide ores solvent extraction and electrowinning technologies are used to recover the copper from the pregnant leach solutionGet Price
This process uses aqueous waterbased solutions to extract and purify copper from copper oxide ores at ordinary temperatures usually in three steps heap leaching solvent extraction and electrowinning Heap Leaching is the process of using percolating chemical solutions to leach out metals Heap leaching is very commonly used for lowgrade ore which would otherwise not beGet Price
A metal oxide is reacted with charcoal If the charcoal carbon is more reactive it will remove the oxygen from the metal oxide and leave a trace of metal in the reaction vessel Start with an oxide of lead then observe what happens to an oxide of copperGet Price
CuO 2 is unstable and decomposes to oxygen and other copper oxides especially when wet Joannis 1885Cu 2 O 3 has not yet been isolated as a pure solid but has been a constituent compound of cuprate superconductors Wang et al 1996Cu 4 O 3 was first described in 1892 Koenig 1892 and when synthesized forms with other copper oxides Morgan et al 1996Get Price
