Among the copper resources in China, copper oxide ore accounts for about a quarter. Most copper deposits have oxidized zones, and some have formed separate large and medium-sized copper oxide deposits. To this end, the development and utilization of copper oxide ore is of great significance to the development of China's copper industry. 1. Optional copper oxide ore Copper oxide ore is generally found in the oxidation zone of the bed. Due to the extremely complex physical and chemical conditions of the oxidized zone, the mineral composition and structure of the oxidized ore are also complicated. The choice of copper oxide ore depends on the type of copper minerals, the composition of the gangue, the symbiotic relationship between the mineral and the gangue, and the amount of mud.  2 Introduction of copper oxide ore dressing method The flotation of copper oxide ore is divided into direct flotation and sulfide flotation. Direct flotation is the earliest application of sodium sulfide activation, directly using collector flotation, including fatty acid flotation, amine flotation, neutral oil emulsion flotation, and mixing collector floatation Selection method, etc. Because copper oxide ore is mostly characterized by high oxidation rate, large mud content, high combined copper content, uneven grain intercalation, mixed oxygen and sulfur, and coexistence of various minerals, it is difficult for the collector to adsorb to the mineral surface. After vulcanization, a fundamental change in the surface of the copper oxide mineral can be achieved. Vulcanization flotation is to add vulcanization agent such as sodium sulfide to the copper oxide slurry for vulcanization, and then add xanthate collector flotation. As a conventional method of flotation of copper oxide, it has been difficult to adapt to the needs of the current complex and difficult-to-select copper oxide. New pharmaceuticals, new processes, and combined flotation processes are increasingly becoming the development trend of flotation of difficult copper oxide. 3 new agent for flotation of copper oxide Since oxidized ore has higher requirements for flotation agents than sulfide ore, it is difficult to achieve the desired effect as a single direct vulcanization, so some combination agents are often used for flotation of oxidized ore. The following highlights the latest flotation copper oxide ore A5 A5 Pharmacy is the latest development from Kunming Metallurgy Research Institute, an oxidized copper ore flotation reagent new success, the agent while both activated, collector, blistering function, the production process without adding other agents, oxidation can be realized Efficient collection of copper mines. In order to prevent counterfeiting, this product uses a binary component, component one is a yellow solid which is not tolerant to water, is the core component of the product, and component two is a liquid diluent. The appearance of component one and some physicochemical properties are completely different from any traditional sulphide ore dressing agent such as xanthate, black drug, sulfur nitrogen, etc. It is a deep yellow solid, completely incapable of water, specific gravity 1.5, pH ≈7, When using, dissolve it with a diluent and add it directly. According to laboratory research, when A5 flotation of malachite, azurite, cuprite, water cholesteric, cholesteric, copper chlorinated or other oxidized copper ore, the concentrate can contain Cu>20%, and the recovery rate is up to 80% good indicator. The new chelating agent A5 has strong selective storage performance for refractory copper oxide minerals, can accelerate the floating speed of refractory copper minerals, and can effectively eliminate the interference of slime to flotation, which is the high efficiency of refractory copper oxide minerals. Collector. Copper conductive rate is very good,machining copper(including Machining Brass,machining bronze) is the use of CNC machining out, including turning, drilling, cutting, and screw teeth, etc.. Machining copper commonly used materials: copper, brass, bronze, beryllium copper. the surface treatment is generally silver plating, gold, some laser LOGO, we have a special inspection department to carry out inspection, and ensure that each size to meet the requirements of the drawings, including machining copper applied in various industries: household appliances, conductive slip ring, communications, medical equipment, industrial automation equipment.
