What is Cupric Oxide?
Copper oxide is an inorganic material with the chemical formula CuO. Insoluble in water, quickly soluble in acid, steady to heat, decays to oxygen at high temperature. It can be minimized to steel copper by feeding hydrogen or carbon monoxide gas at high temperature. Copper oxide is heated up in the air, as well as at concerning 1050 ° C, oxygen is launched and lowered to cuprous oxide. In hydrogen or carbon monoxide gas circulation, it can be quickly decreased to metal copper also below 250 ° C. Although copper oxide is insoluble in water, it is soluble in liquid alkali steel hydroxide option.
Copper oxide powder is a brown-black metal oxide powder with a wide variety of uses. Average copper oxide is a multifunctional great inorganic product with a large range of uses, mostly used in the fields of printing and dyeing, glass, ceramics, medicine as well as catalysis. Nano-copper oxide can be made use of as driver, stimulant carrier and also electrode activation product, as well as can additionally be made use of as rocket propellant. As the main part of catalyst, copper oxide powder has many features in oxidation, hydrogenation, NO, CARBON MONOXIDE, reduction and hydrocarbon combustion extensively used in catalytic reactions.
Copper(II) oxide is used for blue-green pigmentation in porcelains. As an all-natural compound created from mining, it is likewise made use of as a precursor for various other copper applications, including fungicides and also timber chemicals. In this capability, it is made use of as an antifouling covering for watercraft hulls and also other exterior, freshwater and also saltwater wood structures. It is also periodically made use of in pet feed, however inaccurately, since it has lower copper bioavailability than lots of other substances, including copper acetate and fundamental copper carbonate. Various other uses consist of the preparation of superconductors, the manufacture of batteries, and also as a catalyst for numerous industrial procedures.

Application of Cupric Oxide
Copper oxide is a crucial p-type semiconductor material with a narrow band gap (1.2-1.5 eV) as a result of its unique residential or commercial properties, such as excellent thermal security as well as photochemical stability, high temperature superconductivity, high electrochemical activity, safe, inexpensive preparation approach, has been commonly used in stimulants, superconducting materials, thermoelectric materials, noticing materials, glass, porcelains, lithium-ion batteries as well as other areas.
Presently, because of the premium optical, electrical, magnetic, and also thermal residential or commercial properties of nanomaterials with different morphologies, the controlled prep work of nanomaterials has ended up being an objective of current product scientists. For example, copper oxide, as one of the most usual change steel oxide, has actually been slowly utilized in lithium-ion batteries due to its high academic details capacity (674mAh g-1), simple preparation, and inexpensive. The conductivity of the electrode as the negative electrode product limits the volume change of the carbon-based energetic product throughout the charging and releasing procedure of the battery, therefore boosting the electrochemical performance of the battery such as relatively easy to fix ability, cycle life, and also charge-discharge stability. Carbon core/copper oxide covering composite electrode for lithium-ion batteries, the core is carbon fiber, and also the shell is a slim layer of copper oxide; the thin layer of copper oxide has an array-type nano-needle structure and also a nano-pore structure; the nano The needle-like structure is on the external surface area of the copper oxide thin layer, and the nano-hole structure is an opening permeating with the copper oxide slim layer.
A kind of prep work method of described carbon core/copper oxide covering composite electrode for lithium ion battery comprises the preparation of copper-plated carbon fiber, the sintering molding of copper-plated carbon fiber and also the surface area oxidation therapy of developing copper-plated carbon fiber really felt. In the modified composite electrode, the nanoporous structure of the copper oxide slim layer contributes to the simple passage of lithium ions in the electrolyte, and then the procedure of lithium insertion and delithiation takes place in the carbon core, consequently increasing the fee and discharge capacity of the lithium-ion battery; carbon core The part is in close contact with the copper oxide covering, which not only enhances the conductivity of the electrode, yet likewise buffers the quantity modification throughout the conversion of copper oxide; the copper oxide shell securely wraps the carbon core part, and also the nano-needle structure of the copper oxide covering is incredibly It considerably reduces the diffusion distance of lithium ions and enhances the efficient get in touch with area with lithium ions, which restricts the development of carbon fiber quantity during the charging and also discharging of lithium-ion batteries and also the procedure of lithium-delithiation, which is conducive to enhancing the relatively easy to fix capacity of lithium-ion batteries as well as cycle life.
Flotation of Copper Oxide Ore
Introduction of Copper Oxide Ore and Flotation Method Used
The buoyancy of copper oxide ore is generally worse than that of copper sulfide ore, and is greatly affected by conditions such as the existence of copper in the mineral and the composition of gangue, for example: copper is in the form of carbonate (Malachite, azurite) have relatively good buoyancy, and the presence of silicate (chrysocolla) has poor buoyancy, free copper oxide is easy to float, and combined copper oxide basically cannot Recovered by a single flotation method. All copper oxide minerals that exist in a separate state are called free copper oxides. All free copper oxides can be dissolved in cyanide solutions. When copper and gangue (such as iron hydroxide) are cemented together, they exist in a certain form Copper oxide minerals are called bonded copper oxides, and the types of cementation are various. They can be mechanically formed as inclusions of very finely dispersed copper minerals in gangue, or chemically formed into isomorphic substances. , It can also form an adsorption-type chromophore, and all combined copper oxides are insoluble in cyanide solutions. The percentage of bound copper in copper oxide is called the binding rate. Gangue minerals mainly composed of silicon (such as quartz) are easier to float, and those mainly composed of carbonates (such as calcite, dolomite, etc.) are more difficult. If they contain a large amount of iron hydroxide and clay Separation is more difficult when slimes are formed, especially when they are closely combined.
The flotation of oxidized minerals mostly adopts the sulfuration method
Due to the high flotation speed of the oxidized ore after sulfidation, the first 1-2 tanks of the first roughing will directly produce concentrate products. The addition method of reagents has special significance for the flotation of copper oxide ore, especially sodium sulfide, which is not only the activator of copper oxide ore, but also the inhibitor of copper sulfide ore, so it is not suitable to add enough at one time when adding. It adopts the method of multi-stage addition in batches, so the addition amount of the first operation (rough selection) in the flotation process is 70-80% of the total amount to ensure that the concentration of sodium sulfide is sufficient but not excessive. When sodium sulfide is used for vulcanization, lime is used as a pH regulator, pH 8.5-9.5, and sodium sulfide can be used to achieve better results. While using sodium sulfide, add an appropriate amount of ammonium sulfate and sodium sulfide at a ratio of 1:1. It can improve the recovery rate of copper oxide ore. The reason is that after adding ammonium sulfate, the pH value drops, which is conducive to the increase of HS- concentration, and the sulfidation reaction is accelerated, which is beneficial to the flotation of copper oxide ore. However, when selecting sulfide and oxidized mixed ore, the excessive amount of ammonium sulfate will inhibit the sulfide minerals, so the addition amount must be strictly controlled.
When mixed with hydroxamate and butyl xanthate, it has a strong collection ability for refractory minerals such as chrysocolla, copper-bearing limonite ore, etc. Sodium hydroxamate has a strong collection ability for sulfide ore at pH10~11. Good collection effect, but when the pH is lower than 8, it is unfavorable to the collection of sulfide ore.
