Molybdenum metal has the characteristics of high temperature resistance, high melting point, and high rigidity. Most of the molybdenum ores currently developed and utilized are molybdenite, which is recovered by flotation process. The embedded particle size of molybdenite is relatively fine, and it is often associated with minerals such as pyrite, chalcopyrite, and galena.
In the field of mineral processing, ball mills are indispensable grinding equipment, and their performance directly affects the efficiency and cost of the entire production line. The filling rate of the ball mill, that is, the volume ratio of the grinding media (such as steel balls and steel rods) inside the mill, is one of the key parameters affecting the grinding efficiency. This article will deeply explore the impact of the ball mill filling rate on the grinding efficiency, and provide a reference for enterprises to optimize the production process.
Rutile is rich in titanium dioxide and is a high-quality raw material often used in the production of titanium dioxide, titanium sponge, titanium tetrachloride and other titanium products. Natural rutile is often associated with quartz, ilmenite and other minerals. If you want to obtain high-grade titanium concentrate, you need to flotate rutile. This article introduces the common methods and equipment for rutile flotation.
Lead-zinc tailings refer to the waste residue discharged after valuable elements are extracted from lead-zinc ore through beneficiation. Common lead-zinc tailings include sulfide lead-zinc tailings, oxidized lead-zinc tailings and mixed lead-zinc tailings. So how to recycle lead-zinc tailings?
Copper, lead and zinc are widely used in military, chemical, and applied materials industries. They often coexist and exist in the form of sulfides in the earth's crust. The surface properties of the three sulfides are very different, which makes it very difficult to separate them. Although copper, lead and zinc mineral resources are abundant, they are of low grade and have fine particle size. This article takes a low-grade copper, lead and zinc sulfide ore as an example to explain the flotation process.
Lead-zinc ore is widely used in metallurgy, chemical industry, building materials and other fields. In recent years, with the development of economy, especially the rapid expansion of automobile industry, lead-zinc ore, as the raw material of lead production essential for battery production, has been in short supply. This article takes a 2,000-ton lead-zinc ore production line as an example to introduce the ore dressing process and equipment.
