Bosite cassiterite-sulfide ore beneficiation method, tin ore fine mud flotation process, comprehensive tin recovery from tailings

Bosite's cassiterite sulfide ore beneficiation method, tin ore fine mud flotation process, and comprehensive recovery of tin from tailings
The beneficiation method of tin ore mainly depends on its own characteristics. Currently, most of the tin concentrate produced in the world Most of them are produced from cassiterite deposits, and the density of cassiterite is higher than that of symbiotic minerals. Therefore, the traditional beneficiation process of tin ore is gravity separation. For example, the cassiterite in tin ore has very fine particle size and can be sorted by flotation process. In addition, since tin minerals often contain various iron oxide minerals, such as magnetite, hematite and limonite, these minerals cannot be well separated from cassiterite by flotation and gravity separation. Therefore, In recent years, magnetic separation operations have appeared in the tin ore beneficiation process. This magnetic separation operation is mainly aimed at separating tin and iron, and can be combined with gravity separation or flotation to separate tin ore.
In short, the beneficiation method of tin ore has broken through the traditional single gravity separation process and entered a new era of combined use of several beneficiation methods. Despite this, gravity separation is still the main method of tin ore beneficiation.
The beneficiation of placer tin ore is similar to the beneficiation of placer gold ore. They are roughed out by gravity separation. Before roughing, they need to be screened by a vibrating screen to remove a large amount of waste rock. Most roughing equipment uses high recovery rates. , large processing capacity, selected as a jig with wide particle size. The coarse concentrate obtained by the jig can be ground again to break up the contiguous state, and then the final concentrate can be obtained by using a shaking table for selection. The jig tailings can be used as sand and gravel aggregate. However, in most cases, many placer tin ores themselves are dissociated into monomers, so they do not need to be crushed. After screening, they can be directly entered into the jig, and the tin inside can be recovered.
Henan Bosite Machinery Manufacturing Co., Ltd. specializes in the production of tin ore beneficiation equipment. Tin ore gravity equipment jigs have a complete range of equipment models and are available in large series. There are more than ten types of jigs for everyone to choose from, which can meet the needs of customers in different categories. Welcome Guangxin old customers to visit our factory.
