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.

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.

Oxidized gold ore is a specific type of oxidized ore, in which the gold element mainly exists in the ore in an oxidized state. In oxidized gold ore, in addition to gold oxidized minerals, it may also contain oxidized minerals of other metals and some gangue minerals. As an important type of gold resource, oxidized gold ore accounts for about 30%-40% of the global gold reserves. Effective development is of strategic significance to alleviating the contradiction between gold supply and demand. This article will focus on the characteristics of oxidized gold ore, the difficulties in refining gold, and the technology of refining gold from oxidized gold ore.

Quartz sand is a mineral particle aggregate with quartz as the main component. Its main component is silicon dioxide, and its content is usually between 90%-99%. It has stable chemical properties, high hardness, and good high temperature resistance and corrosion resistance. It is used in construction, glass, electronic information, chemical industry, etc. According to the different components of quartz sand, the application environment is also different. Here we will introduce the classification and application of quartz sand and the quartz sand extraction process .

In the field of gold resource development, carbon slurry gold extraction technology is widely used because of its simple operation and strong adaptability. However, with the decline in the grade of gold mine resources and stricter environmental protection requirements, the traditional carbon slurry gold extraction process faces problems such as low gold recovery rate, high activated carbon consumption, and insufficient process efficiency. Based on the existing problems of carbon slurry gold extraction technology, this article introduces the optimization scheme of carbon slurry gold extraction technology from the aspects of pretreatment, leaching, adsorption, desorption electrolysis and activated carbon regeneration.

Fluorite, with a chemical composition of CaF₂, is an important strategic non-metallic mineral resource in the world and plays an irreplaceable role in many fields such as metallurgy, chemical industry, and optics. With the rapid development of global industry, the strategic position of fluorite has become increasingly prominent. However, natural fluorite often coexists with gangue minerals such as calcite, barite, and quartz, and has a low grade. Therefore, how to obtain high-quality fluorite products is the key. This article will focus on the significance, process and application of fluorite beneficiation.

At the moment when the new energy industry is booming, lithium resources, as the main raw material for lithium-ion batteries, have become increasingly strategically important. In addition to common lithium ore resources such as spodumene and lithium mica, carbonate clay lithium ore is also a resource for obtaining lithium, and it has entered people's field of vision as an emerging lithium ore resource. So what are the beneficiation processes for carbonate clay lithium ore? Let's find out together!

In the field of phosphate ore resource development, flotation is an important means of mineral processing, and the grade of the ore is one of the key factors that determine its feasibility. Recently, a customer came to consult about the question of how much phosphorus grade can be flotated. Let's answer this question and list several common phosphate ore flotation methods.
