how do i seperate copper oxide into copper and oxygen with an acid in zambia

The oxidation states of the elements oxygen in the gas and copper in the metal are 0 In sulphur dioxide the oxygen has an oxidation state of 2 and the sulphur 4 That means that both the copper and the oxygen have been reduced decrease in oxidation state The sulphur has been oxidised increase in oxidation state...We are a professional mining machinery manufacturer, the main equipment including: jaw crusher, cone crusher and other sandstone equipment;Ball mill, flotation machine, concentrator and other beneficiation equipment; Powder Grinding Plant, rotary dryer, briquette machine, mining, metallurgy and other related equipment. which can crush all kinds of metal and non-metallic ore, also can be dry grinding and wet grinding.If you are interested in our products or want to visit the nearby production site, you can click the button below to consult us.Welcome to our factory to test machine for free!
