What is Tailing Reprocessing Method?

Although the content of useful components in tailings is relatively low, using the advanced and reasonable mineral processing technology to reprocess tailings can also recover the useful components in tailings to a large extent, so as to fully recover and utilize resources, reduce the output of final tailings and relieve the pressure of tailings on the environment. At present, the common tailings reprocessing methods mainly include:

1. Adopting the froth flotation method to treat the tailings containing hard boracalcite, zinc oxide, apatite

Due to the development of new flotation reagents and froth flotation processes, some tailings produced by the simple mineral processing processes, especially the old tailings, can be recycled to obtain the concentrate products by the froth flotation and method.

2. Using the new gravity separator to recycle the fine mineral in tailings

After the improvement, many gravity separators can be used in the fine and ultrafine tailings reprocessing, such as vertical centrifugal concentrator, shake table with the compound force field, the centrifugal machine with the compound force field.

3. Using the microbial treatment and leaching method to treat the tailings

This tailings disposal method mainly uses the biochemical action of microorganisms to improve the tailing properties and extracts the harmful metal ions in the tailing by means of microbial leaching or microbial mineralization, so as to avoid the environmental pollution.
