Copper is an important non-ferrous metal, and its production and sales volume are second only to aluminum. Copper metal is mainly extracted from sulfide ores, and mineral resources are relatively abundant. Oxide copper ores account for a large proportion of them, and can be roughly divided into two categories: one is the oxide copper ore with simple composition and easy to handle, which is often treated by flotation; the other is the oxide copper ore that is difficult to handle, which is mostly treated by chemical methods. Although the mineral processing index obtained by chemical treatment methods is better, chemical methods such as acid leaching have a long treatment cycle and slow recovery rate improvement, so flotation is often used as the preferred method for treating oxide copper ores. The following will elaborate on two commonly used flotation methods: direct flotation and sulfide flotation.Details>>
Copper ore enrichment is the key process to increase the copper content in copper ore to reach the economic utilization level. Common copper ore enrichment methods are mainly flotation, gravity separation, magnetic separation and leaching. Each enrichment method is different. Let's learn about it together.Details>>
Chalcopyrite (CuFeS₂) and pyrite (FeS₂) are common sulfide minerals that often coexist in ores. Among them, chalcopyrite is one of the main minerals for obtaining copper, and pyrite coexists with it, which will affect the quality of copper concentrate. In the beneficiation process of copper ore, effective separation of chalcopyrite and pyrite is crucial to improving the grade and recovery rate of copper concentrate. However, there are many similarities between the two in crystal structure, chemical composition, physical properties, etc., and separation is somewhat difficult. At present, the common chalcopyrite copper ore beneficiation and separation methods are mainly flotation, magnetic separation and gravity separation.Details>>
Copper flotation is an important mineral processing technology in the development of copper resources. Different types of copper ores have different flotation methods and technical options due to their differences in ore composition and physical properties. By reasonably adjusting crushing, grinding, slurry adjustment and the selection of flotation reagents, the recovery rate of copper minerals and the quality of concentrate can be effectively improved. The following will introduce the flotation process of copper sulfide and copper oxide, the flotation process and the selection of flotation reagents to help you better understand copper flotation.Details>>
Lead is a silvery-white metal with a slightly blue tint, which has good ductility, softness and corrosion resistance. In the market, lead is mainly used to manufacture products such as batteries, cable sheaths, lead pipes, lead plates, etc. It also plays an important role in chemical, metallurgical, and construction fields. Understanding the lead beneficiation process is of great significance for improving the recovery rate and quality of lead, meeting market demand, and realizing the sustainable use of resources. At present, the common lead ore beneficiation methods include flotation, gravity separation, and magnetic separation. Let's learn about the principles and characteristics of these lead beneficiation methods.Details>>
Lead-zinc metals are widely used in electrical, mechanical, military, metallurgical, chemical and other fields. With the increasing demand for metals year by year, it is urgent to improve the recovery rate of metal ores in ores. Oxidized lead-zinc ores can be divided into three types according to the degree of oxidation: sulfide lead-zinc ores, oxidized lead-zinc ores and mixed lead-zinc ores. Among them, sulfide lead-zinc ores and mixed lead-zinc ores can be treated by flotation, while oxidized lead-zinc ores need to be treated by flotation in addition to beneficiation metallurgy or single metallurgy due to their fast oxidation rate, high mud content and close symbiosis with limonite. The following will introduce the above three beneficiation technology of lead-zinc ores respectively.Details>>
Lead-zinc ore in my country is mainly sulfide ore, mainly galena and sphalerite. For this type of lead-zinc ore, flotation is mainly used to achieve mineral separation and separation. However, with the gradual reduction of sulfide ore, oxidized lead-zinc ore has gradually entered the developers' field of vision. For separation, it is more difficult. In the flotation process, the selection of lead-zinc ore flotation method is the top priority, but flotation reagents cannot be ignored. This article will focus on the flotation reagents of lead-zinc ore.Details>>
Copper, lead and zinc are three important non-ferrous metals, and all of them are sulfur-loving elements. They often exist in the form of sulfides in the earth's crust. Copper, lead and zinc minerals come from the sulfide ore oxidation zone. They are the products of complex weathering (physical, chemical and biological effects) after the sulfide deposits are exposed to the surface. In addition, copper, lead and zinc often exist in a symbiotic relationship. The relationship between minerals is complex and the separation is difficult. In terms of ore separation methods, flotation is mainly used to achieve separation. Let's introduce the flotation methods of copper oxide, lead oxide and zinc oxide respectively.Details>>
In order to improve the comprehensive utilization rate of associated valuable elements and resources, people have conducted a lot of research and improvements on the flotation separation process of pyrite and chalcopyrite. These improvements are aimed at adapting to the changes in mineral flotation characteristics and ore properties, and optimizing resource recovery rate and processing efficiency. At present, there are five commonly used flotation separation process flows: direct flotation separation process flow, preferential flotation process flow, mixed-preferential flotation process flow, mud and sand separation process flow, and combined beneficiation and smelting process flow. Each process has its specific applicable conditions and operating characteristics, which can effectively cope with different ore types and processing requirements. This article will introduce the status of these five flotation separation process flows in detail, and explore their respective scope of application, process flow and advantages and disadvantages.Details>>
Copper metal resources are widely used in industrial production and social life. With the continuous development of the times, the demand for them is increasing. However, since ore is a non-renewable resource, it is of great significance to the redevelopment of copper mines. Due to the backward technologies of early mining, mineral processing and equipment manufacturing, some valuable copper metals were left in the tailings. Therefore, the reselection of this part of the tailings is the main channel for obtaining the same resources. Let's take a look at what are the reselection processes for copper oxide tailings?Details>>
With long-term mining, the abundant copper, molybdenum and other ores have been basically mined out, while the demand for mineral resources in modern industry has only increased. Therefore, expanding the amount of available resources and recycling resources are new development directions. Minerals are non-renewable resources, and recycling is difficult. It is necessary to develop difficult-to-select ores as much as possible. Traditional beneficiation processes face huge challenges for beneficiation of difficult-to-select, fine-grained or severely weathered ores. New process methods are breakthroughs. At present, many research institutions and universities have begun to develop new beneficiation process technologies. Let's take a look at some new types of copper-molybdenum ore beneficiation processes.Details>>
Lead-zinc tailings are waste materials obtained after ore dressing. The concentrate is selected and refined, while the tailings are piled in the tailings pond. In the early days, tailings ponds were mostly stored in wet discharge. Over the years, tailings water may leak out of the mountain and affect the surrounding land and environment. In case of heavy rain, it may also cause dam collapse. In order to improve and avoid such adverse factors, the focus has been on dry storage of tailings. Although the adverse factors have been reduced, the storage of a large amount of tailings has occupied a large amount of land, seriously wasting land resources. So in addition to dry stacking, what other methods are there for lead-zinc tailings treatment? Let's learn about it together.Details>>
