A mining company originally operated two mature 900 t/d silver-lead-zinc-gold polymetallic ore processing lines with stable output. However, due to growing market demand and the company's development strategy, the client aimed to expand production capacity by adding a new 1,500 t/d processing line adjacent to the existing plant.

Calcite-associated fluorite ore mainly consists of calcite (CaCO₃) and fluorite (CaF₂), with associated minerals including quartz, barite, sulfides, and trace amounts of rare earth elements. The primary beneficiation method for this type of ore is flotation. However, due to the similar physical and chemical properties of calcite and fluorite—both being calcium-bearing minerals—their separation via flotation presents significant challenges. This article provides a detailed explanation of the separation process.

There are various types of fluorite ores. Based on the associated gangue minerals, they can be classified into sulfide-type, calcite-type, barite-type, and quartz-type fluorite ores. Among them, quartz-type fluorite ores have the largest reserves and are the most widely distributed.

Global fluorite resources are mainly distributed in countries such as China, Mexico, South Africa, and Mongolia. Today, fluorite mining faces significant challenges. On one hand, high-grade fluorite resources with CaF₂ content above 97% are gradually being depleted. On the other hand, increasingly stringent environmental protection policies are accelerating the development of green mines. Therefore, selecting appropriate mining and beneficiation methods is key to achieving a high recovery rate while complying with environmental regulations.

Faced with both rising demand across various industries and the depletion of molybdenum ore reserves, how can beneficiation and deep processing technologies be improved? Keep reading — this article will guide you to the answer.

Fluorite is an important strategic resource. Pure fluorite ores are rare; most fluorite deposits are associated with other minerals, and antimony-bearing fluorite is one such type. Antimony is widely used in flame retardants, alloy materials, and other fields, while fluorite is a key raw material in the fluorine chemical industry chain. In processing antimony-containing fluorite, how can resource waste be minimized and the comprehensive recovery of these two valuable elements be achieved? This article will explain the detailed process flow.

Tungsten-bearing fluorite mineral resources are primarily distributed in China's Jiangxi, Hunan, and Guangdong provinces, with additional deposits found in countries such as Mongolia and North Korea. Tungsten is a strategic metal, widely applied in aerospace, aviation, and the new energy vehicle industries. Fluorite, a critical raw material for producing fluorine, plays an essential role in the fluorochemical sector. Therefore, the comprehensive utilization of tungsten-containing fluorite resources is of great importance.

Manganese is an essential metallic element, widely distributed in nature, and found in nearly all types of ores and silicate rocks.In modern industry, manganese and its compounds are primarily used in steelmaking and ironmaking, especially for deoxidation, desulfurization, and alloy production.
