In modern industry, nickel and cobalt, as important metal elements, are an important part of the development of different fields. Nickel plays an important role in the steel field such as stainless steel, alloy structural steel, as well as in the battery, electroplating and other industries; cobalt plays a key role in high-end manufacturing industries such as lithium batteries, super alloys, and cemented carbide. With the rapid development of industries such as electric vehicles and electronic equipment, the demand for nickel and cobalt has increased dramatically.Details>>
On the stage of nickel resources, laterite nickel ore has gradually emerged with its rich reserves. However, its complex ore properties have brought considerable challenges to ore dressing work. Its complex composition and difficulty in extraction have posed severe challenges to processing technology. In-depth research on the processing technology of laterite nickel ore is of great significance for ensuring the stable supply of nickel resources and promoting the sustainable development of the nickel industry.Details>>
Silver is an important precious metal and a strategic resource with a wide range of industrial uses and high economic value. It is an indispensable raw material in key areas such as high-end electronic equipment, aerospace, and national defense weapons. Pure silver raw materials are obtained through beneficiation. Common silver ore beneficiation methods mainly include flotation, gravity separation, cyanidation, etc. This article will introduce the silver ore gravity separation process in detail.Details>>
In the modern industrial system, nickel, as an important non-ferrous metal, is widely used in stainless steel, batteries, alloys and other fields. As an important source of nickel resources, the development of its metallurgical technology is of great significance to ensure the supply of nickel and promote the upgrading of related industries. At present, the common laterite nickel metallurgical technologies are mainly pyrometallurgy and hydrometallurgy. So what is the difference between the two? Let's learn about it together.Details>>
As the main source of nickel metal extraction, nickel ore plays a key role in the modern industrial system. According to the difference in ore properties, nickel sulfide and laterite nickel are the two main types of nickel minerals, and they have many differences in many aspects. Let's introduce them from several dimensions.Details>>
As an important source of nickel resources, laterite nickel ore occupies a pivotal position in the global nickel industry. With the increasing depletion of sulfide nickel ore resources, the development and utilization of laterite nickel ore has attracted more and more attention. However, its complex ore properties have brought considerable challenges to the dressing work. In this article, we will introduce the laterite nickel ore dressing method.Details>>
Laterite nickel ore is a secondary deposit formed by ultrabasic rocks (such as peridotite, serpentinite, etc.) under long-term weathering, and is a typical weathering crust mineral resource. This type of ore is mostly red, brown or yellow in appearance, and its texture is similar to soil, hence the name. Its formation process is accompanied by complex physical, chemical and biological effects, making laterite nickel ore not only an important source of nickel metal, but also contains a variety of elements such as iron, magnesium, and cobalt, with significant comprehensive development value. Unlike sulfide nickel ore, the nickel element in laterite nickel ore mainly exists in the form of oxides or hydroxides, which determines that its extraction process is significantly different from that of sulfide nickel ore.Details>>
Nickel sulfide ore is one of the important sources of nickel resources, mainly composed of nickel-containing sulfides such as pentlandite ((Ni,Fe)9S8) and pyrite (Ni3S2). Since these minerals usually coexist with other metal sulfides (such as copper, cobalt, platinum group metals, etc.), and are often accompanied by a large amount of gangue minerals, appropriate beneficiation processes are needed to improve the grade and recovery rate of nickel. At present, the common nickel sulfide beneficiation processes mainly include flotation, magnetic separation, gravity separation, oxidative roasting-leaching, bioleaching and other methods. Let's learn about it together!Details>>
Laterite nickel ore is a nickel-containing oxidized ore deposit formed by long-term weathering and leaching of nickel-containing peridotite in tropical or subtropical regions. Its mineral resources are rich and widely distributed. With the rapid development of the global economy, nickel, as an important strategic metal, is in increasing demand. As one of the important sources of nickel, laterite nickel ore has also been gradually concerned about mineral processing development. In terms of mineral processing methods, according to the properties of laterite nickel ore, flotation is usually used to complete the selection. There are many methods for flotation of laterite nickel. This article will focus on the reverse flotation method and process of laterite nickel.Details>>
Nickel oxide is an inorganic compound composed of nickel and oxygen, with the chemical formula NiO. Nickel oxide is insoluble in water and liquid ammonia, but soluble in sulfuric acid, nitric acid, hydrochloric acid and ammonia water. It has a cubic crystal structure, similar to sodium chloride, in which each nickel atom is surrounded by six oxygen atoms in close proximity, forming a regular octahedron with the nickel atom at the center. Due to the complex nature of nickel oxide ore, flotation is the main method for ore dressing. Currently, the common nickel ore flotation includes direct flotation, sulfide flotation and combined flotation.Details>>
Copper in copper-nickel ores mainly exists in the form of chalcopyrite, while nickel mainly exists in the form of free nickel sulfides such as pentlandite, pyrrhotite and pyrrhotite, and a considerable part of nickel is present in pyrrhotite in the form of "isomorphism", and there is also a small amount of nickel silicate. Sulfide copper-nickel ore types are mostly magma-melted copper-nickel ore, of which nickel content above 3% is rich ore and can be directly smelted, while nickel content below 3% requires ore dressing. Among the ore dressing methods, flotation is the main method, and gravity separation and magnetic separation are usually auxiliary.Details>>
The separation of copper and nickel can be carried out during the beneficiation and smelting process. Due to the high cost of smelting separation and many restrictions on conditions, the flotation method is basically used for copper-nickel beneficiation separation.The flotation of copper-nickel ore can be divided into four types: direct priority flotation, mixed flotation without separation, and mixed flotation followed by separation flotation.Details>>
