Copper(II) oxide or cupric oxide is the inorganic compound with the formula CuO. A black solid, it is one of the two stable oxides of copper, the other being Cu 2 O or cuprous oxide.As a mineral, it is known as tenorite.It is a product of copper mining and the precursor to many other copper-containing products and chemical compounds.
An economic simulation model was developed to predict the amount of copper recovered from copper oxide deposits and the cost of producing it as a function of the deposit parameters. The economic simulation model includes models of fragmentation design and cost, copper extraction, solution distribution and recovery, effluent solution cutoff grade, and financial analysis.
Sep 09, 2010· Figure 3 compares the ReaxFF and QM results for copper oxide and copper hydroxide phases, indicating that ReaxFF is capable of describing the configurational landscape of the Cu II O-phases as well as the energetics of copper oxidation and hydroxylation.
Copper(II) oxide can be prepared pyrometallurigically by heating copper metal above 300 deg C in air; preferably 800 deg C is employed. Molten copper is oxidized to copper(II) oxide when sprayed into an oxygen containing gas. Ignition of copper(II) nitrate trihydrate at about 100-200 deg C produces a black oxide.
Jul 10, 2019· Although copper is an essential element for mammals, many of its compounds, including both forms of copper oxide, are toxic in all but small doses. If inhaled, copper(I) oxide can cause shortness of breath, coughing, and damage to the respiratory tract.

The Copper Development Association Inc. (CDA) is the market development, engineering and information services arm of the copper industry, chartered to enhance and expand markets for copper and its alloys in North America. CDA's website is an excellent resource for information about copper, copper alloys, and their many uses and benefits.
The range of Reynolds numbers is between 10,000 and 60,000 and the volume fraction of copper oxide nanoparticle in 0%, 2%, and 4% was examined. In this numerical simulation, the effects of the changes in parameters such as dimensions of semi-attached rib, volume fraction of the nanoparticle, and Reynolds number were considered.
It was also concluded that the X-ray absorption spectra were quite consistent with the initial oxidation products on chalcopyrite and bornite surfaces being iron oxide species, and inconsistent with the concomitant formation of copper-oxygen species.
