The fineness to which the ore is ground has a considerable effect on the kind of oil necessary. A certain degree of ...
Explaining the Process of Froth Flotation
The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In general, the minerals which …

design of a flotation equipment for cupper ore concentration
Application of Ore froth flotation 1.Ore froth flotation can be widely used in the beneficiation of non ferrous metals, black metals and nonmetals. (2) When the impeller of the lead zinc Ore froth flotation begins to rotate, negative pressure is formed, making the air and pulps at the bottom and middle part of the tank enter the mixing zone.
Copper Process Flowsheet Example
The crushed ore will be processed by means of semi-autogenous and ball mill grinding followed by rougher flotation, regrind, cleaner flotation, and dewatering to produce copper concentrate. The concentrate will be trucked via the existing road network in the area to a port facility for shipment to smelters.

Froth Flotation Handbook
What is Flotation. Flotation, as the term is applied to ore concentration, means the separation of one of the constituents of an ore from the remainder by causing it to float at or above the surface of a pulp consisting of the finely pulverized ore and water. Minerals that float. Minerals that float have a metallic, adamantine, or resinous ...

Copper Processing
Froth flotation: Following mining, transporting, and crushing to the required size, the crushed ore is further processed through a mill and then secondary milling and classification. Water is added into the milling circuit to create a slurry. The slurry is transported to a flotation circuit where the copper mineral is separated from gangue.
