Description
Technical field
The present invention relates to mineral and smelt, be specially a kind of preparation method of ultrafine copper oxide powder.
Background technology
Cupric oxide powder is a kind of important multi-functional meticulous inorganic materials, is widely used in dyeing, pottery, glass and medical industries at present.As the staple of catalyzer, cupric oxide powder is widely used in multiple catalyst reactions such as oxidation, reduction simultaneously.Ultrafine copper oxide powder particularly, it is little to have a particle diameter, and specific surface area is big, and characteristics such as catalytic activity height have more wide application prospect at aspects such as electricity, magnetic catalysis.
The main method of preparation ultrafine copper oxide powder has solid reaction process, liquid phase method at present.
Solid reaction process is with metal-salt and MOX thorough mixing according to a certain percentage, calcines after the grinding, directly obtains the method for ultrafine copper oxide powder.This method is easy to operate, and technology is simple, and the powder that still generates is reunited easily, need carry out secondary and pulverize.
The liquid phase reaction method comprises: direct precipitation method, complex-precipitation method, hydrothermal method.
Direct precipitation method is in soluble copper solution, directly to add precipitation agent, produces deposition under certain condition, again with throw out filtration, washing, dry, thermolysis, thereby obtains the ultrafine copper oxide powder.This method equipment is simple, easy and simple to handle, be difficult for introducing magazine, but negatively charged ion is more hard to manage.
The complex-precipitation method is earlier mantoquita and complexing agent to be generated complex compound, and reaction obtains throw out with precipitation agent again, then with throw out filtration, washing, dry, thermolysis.Obtain the ultrafine copper oxide powder.This method cost is low, and is simple to operate, and raw material is easy to get.
Hydrothermal method is in special closed reaction vessel (autoclave); With the aqueous solution as medium; Create the reaction environment of a HTHP through reactor drum heating, make usually water insoluble or be insoluble in the substance dissolves and the crystallization again of water, water is as a kind of chemical composition in water-heat process; It is a solvent, is again the transmission media of pressure.The cupric oxide powder crystal morphology that this method obtains is good, and particle is big, but process is complicated.
Summary of the invention
The technical problem that the present invention solved is to provide a kind of preparation method of ultrafine copper oxide powder, provides a kind of with low cost, is suitable for scale operation, non-wastewater discharge, and product purity is high, the preparation method of particle superfine cupric oxide powder.To solve the shortcoming in the above-mentioned background technology.
The technical problem that the present invention solved adopts following technical scheme to realize:
A kind of preparation method of ultrafine copper oxide powder; With the copper mine is raw material, adopts spray roasting to prepare the ultrafine copper oxide powder, and the tail gas that produces in the spray roasting process simultaneously absorbs processing; Being back into the product system recycles; Shortened technical process, and can realize the environmental protection of ultrafine copper oxide powder, large-scale industrialized production through the heavy granularity of controlled oxidation copper for a long time of control dehydration, roasting and crystal.
Its concrete operations step comprises:
One, select materials: the employing copper mine is a raw material, after leaching reaction, obtains the solution of mantoquita, and this copper salt solution is cupric chloride, copper sulfate or copper nitrate solution.
Two, spray: above-mentioned copper salt solution is sprayed obtains the spray droplet of mantoquita.
Three, calcining: above-mentioned spray droplet under air or oxygen atmosphere, is placed the High Temperature Furnaces Heating Apparatus calcining of 450 degree-1100 degree, obtain the ultrafine copper oxide powder, emit the tail gas of containing water vapor, sour gas simultaneously.
Four, tail gas absorbs: the tail gas that produces in the high-temperature calcination process is sprayed absorption, obtain acid solution, this acid solution can be back to the reaction in the process noted earlier, has realized recycle.
Beneficial effect: the present invention has the following advantages:
1. the cupric oxide powder that obtains is a spheroidal particle, and particle is little, and specific surface area is big, epigranular, good dispersivity.
2. directly adopting the copper salt solution after leaching is raw material, has shortened technical process, provides cost savings.
3. realized recycle, the sour gas that high-temperature roasting produces absorbs processing, can be reused for leaching process, has reduced production cost, is fit to scale operation.
Embodiment
Give an actual example below and describe the present invention.
The employing copper mine is a raw material, after leaching purification, obtains highly purified copper salt solution.
Above-mentioned copper salt solution is under high pressure carried out press atomization, obtain the vaporific drop of mantoquita.The vaporific drop of the mantoquita that obtains under the atmosphere of air or oxygen, is placed under 800 degree and carries out roasting, obtain cupric oxide powder, emit the tail gas of containing water vapor, sour gas simultaneously.
Through the control dewatering time, the heavy granularity of controlled oxidation copper powder body for a long time of roasting time and crystal.The tail gas that produces in the roasting process obtains acid solution after spraying absorption, can return to be used for leaching process.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification sheets just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The scope of the claimed invention by the appended claims and their equivalents defined
