In the modern industrial system, fluorite ore, rich in calcium fluoride, is hailed as the "second-generation rare earth" and is an indispensable strategic resource in fields such as metallurgy, chemical engineering, and building materials. From steelmaking fluxing to fluorine chemical raw materials, from optical glass manufacturing to new energy material production, the application value of fluorite ore runs through the entire industrial chain. However, fluorite deposits in nature often coexist with gangue minerals such as quartz, calcite and dolomite, and effective separation needs to be achieved through scientific beneficiation methods. This article will introduce the beneficiation methods of fluorite ore from different perspectives.

Polymetallic rich iron ore is a kind of mineral resource with complex composition. Besides the main iron ore, it often contains a variety of metal minerals, including copper, zinc, lead, silver, rare earths, cobalt and nickel ores, etc. This type of iron ore is closely associated with other minerals and is a difficult-to-select type of iron ore. In addition, apart from iron which can be enriched, other valuable metals also have enrichment value. Therefore, this article will focus on introducing the beneficiation process of metal iron ore to see how it recovers iron and other metal minerals.

Gravity separation is one of the main means of rock gold ore beneficiation, especially suitable for processing coarse-grained and high-grade rock gold ore. In the beneficiation process, grinding particle size, as a key factor in the gravity separation process, directly determines the dissociation and gravity separation efficiency of minerals. So in the gravity separation process, what are the requirements of different gravity separation methods for particle size? In this article, we will analyze and answer from multiple angles!

As the cornerstone of global economic development, the mining industry provides indispensable basic raw materials for various industries. From steel and cement required in the construction field, to key metals such as copper and lithium relied on by the electronics industry, to coal and oil in the energy industry, the products of the mining industry are widely used in all aspects of social economy.

Lithium carbonate is a white monoclinic crystal. In terms of chemical properties, lithium carbonate can react with acid to form corresponding lithium salts, can react with carbon dioxide to form acid carbonate, and can be decomposed into lithium oxide and carbon dioxide at high temperature. So what are the types of lithium carbonate ores? What are the processes, equipment and extraction methods of lithium carbonate beneficiation? This article will introduce lithium carbonate beneficiation from these four dimensions.

Fluorite (fluorite) is an important non-metallic mineral, which is widely used in many fields such as metallurgy, chemical industry, and building materials. In the process of fluorite beneficiation, flotation is a common and important method, and grinding particle size is one of the key factors affecting the flotation effect of fluorite.

Recently, the price of gold has fallen sharply, but it has no impact on gold mine development. As easily exploitable rich ore resources gradually decrease, poor ores, fine-grained embedded ores, and complex multi-metallic paragenesis ores have become the main development force. For this type of gold mine, flotation gold extraction is often used to achieve recovery.

Flotation is one of the commonly used ore dressing technologies in gold ore dressing plants. It is suitable for the dressing of various complex gold ores, especially in the treatment of difficult-to-select gold ores such as fine-grained intercalation and polymetallic paragenesis. In the flotation process, reagents are the key. The hydrophobicity and hydrophilicity of the mineral surface are changed by adding reagents to separate them. Among them, frothers, as the key medium for constructing the gas-liquid interface, directly affect the generation and stability of bubbles and the fluidity of the foam layer, and then determine the core indicators such as gold recovery rate and concentrate grade. This article will introduce the commonly used frothers in gold mines.
