Introduction of feldspar beneficiation process
Generally, this type of ore deposits need to be processed by flotation to obtain feldspar concentrate. The main processes of beneficiation principles are: Crushing operation: The raw ore is crushed to about 20mm by coarse crushing ( jaw crushe r) and medium crushing (cone crusher); Grinding and grading operations: After being mixed, …
