29 Crushing Process Of Platinum Ore Description

mineral processing - wikipedia,crushing and grinding are the two primary comminution processes. crushing is normally carried out on 'run-of-mine' ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. in comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition..crushing & screening plant design factors,crushing circuit “d” shows a very practical arrangement even for large-tonnage plants, enabling both the primary crusher and the secondary crusher to be in the same crushing building and to utilize the minimum amount of conveying. there is a great deal of merit to this crushing layout “d,” for the same conveyor belt can handle the products from two crushers and thus the minimum amount of.

The Properties And Applications Of Platinum

The Properties and Applications of Platinum

the first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'. during flotation, air is pumped through the ore-water slurry. platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining.
