The invention belongs to the technical field of ceramic production, and particularly relates to high-quality copper red glaze, copper red glaze porcelain and a preparation method thereof. The copper red glaze is prepared from feldspar, quartz, wollastonite, copper oxide, calcite, malachite, talcum powder, Sanbao mud and glaze stone. According to the invention, the raw ore is taken as the main raw material, the raw ore has the advantages of low cost and environmental protection, in addition, the unique internal structure and components of the raw ore can endow porcelain with excellent color and luster, so that the surface of the copper red glaze is smoother, the color is more gorgeous, and the copper red glaze is more layered. Meanwhile, by strictly controlling the conditions and parameters of the preparation process, the cracking rate and defects of the glaze surface can be greatly reduced, and the quality of the copper red glaze is higher.

The invention discloses a flotation inhibitor for copper oxide minerals and a flotation method for copper oxide or copper oxide cobalt ores, and belongs to the technical field of mineral separation. The copper oxide mineral flotation inhibitor comprises sulphide salt, dithiocar-bamate and cysteine, is used in a copper oxide or copper oxide cobalt ore reverse flotation system, and can realize high-selectivity inhibition on copper oxide minerals such as malachite so as to ensure that calcium magnesium carbonate gangue minerals are efficiently collected by a fatty acid collector, so that the flotation efficiency of the copper oxide minerals is improved. Therefore, the calcium-magnesium gangue minerals can be directly removed through reverse flotation, the recovery rate of the calcium-magnesium gangue minerals in foam products is 90% or above, the leaching acid consumption of copper oxide or copper oxide cobalt ore concentrate is greatly reduced, and the production cost is greatly reduced.

The copper oxide mineral flotation inhibitor comprises sulfide salt, dithiocarbamate and cysteine, is used in a copper oxide or copper oxide cobalt ore reverse flotation system, can realize high selective inhibition of copper oxide minerals such as malachite, can ensure high efficient collection of calcium magnesium carbonate gangue minerals by a fatty acid collector, and thus calcium magnesium gangue minerals can be directly removed by reverse flotation, the recovery rate of calcium magnesium gangue minerals in froth products is above 90%, acid consumption of copper oxide or copper oxide cobalt ore concentrate leaching is greatly reduced, and production cost is greatly reduced.

The invention belongs to the technical field of mineral processing, and discloses a flotation collecting agent, a preparation method of the flotation collecting agent and application of the flotation collecting agent in refractory copper oxide ores. Slowly adding concentrated sulfuric acid into linoleic acid at 0 DEG C under a stirring condition; raising the temperature; after reacting for a preset time, adding water to stop the reaction; and the flotation collecting agent is obtained. Molecules of the flotation collecting agent simultaneously contain two active functional groups including carboxyl and sulfo which can react with the surface of copper oxide mineral, so that the covering area of the agent is enlarged, the collecting capacity of refractory copper oxide ore is enhanced, and the refractory copper oxide ore such as pseudomalachite can be effectively recovered; the preparation method is simple and efficient, raw materials are wide in source, and meanwhile the preparation method can be suitable for flotation of different types of copper oxide ore; the flotation collecting agent is good in dispersing performance in ore pulp, high in foaming capacity, good in application effect and high in recovery rate, and a foaming agent does not need to be added in the flotation process.

The invention discloses an efficient malachite flotation recovery method based on mineral surface low-temperature hydrogen plasma modification, and belongs to the technical field of malachite beneficiation and purification processes. The efficient malachite flotation recovery method comprises the following steps: (1) performing low-temperature hydrogen plasma pretreatment on malachite raw ore at room temperature; (2) adding deionized water into the malachite raw ore subjected to low-temperature hydrogen plasma treatment for size mixing; (3) performing direct flotation to separate malachite and quartz; and (4) the foam product is dried, and malachite concentrate obtained after flotation separation and purification is obtained. According to the method, the surface of the malachite is treated through the low-temperature hydrogen plasma technology, the good flotation recovery effect is achieved, the collecting efficiency of xanthate on the malachite is remarkably improved, the dependence of traditional copper oxide ore flotation on a vulcanizing agent is broken through, and a new strengthening way is provided for malachite flotation.
