Closed Circuit Flotation with Regrinding Flowsheet
DESCRIPTION: Regrinding of scavenger flotation concentrate middling OR flotation cleaner tailing and refloating the ground product in closed circuit cleaning. ORE TREATED: Flotation middling containing valuable mineral particles attached to the gangue particles and …
Flash Flotation with Closed Circuit Grinding
Flotation in Grinding Circuits Hydrocyclones are used in many grinding circuits to make a size separation which ideally sends the fine ore fraction to conventional flotation and the coarse fraction back to the mill for further grinding. The separation results not …
Basic Flotation Circuit Design
The slurry flow then enters the feed end of the flotation cells. The slurry at this point is called the HEADS of the circuit. The mineral is then separated and flows over the overflow into a trough called a flotation cell LAUNDERER. The OVERFLOW is now called the flotation CONCENTRATE of the circuit.
Flotation Circuit - an overview | ScienceDirect Topics
3.1 Flotation circuit without grinding. The example of flotation circuit without grinding considered the concentration of copper ore. The feed to the circuit corresponded to 6 t/h of chalcopyrite (33% of copper), 12 t/h of chalcopyrite slow (16% of copper), and 300 t/h of gangue. The superstructure considers five flotation stages.

The rougher and scavenger concentrates may be reground to a predetermined liberation size and then subjected to two or three stages of cleaner flotation to produce a final flotation concentrate. Cleaner flotation tailings is an intermediate product and is recycled within the flotation circuit.

The test work we have done on a fairly limited sample of fresh ore indicates that the silver rougher flotation concentrate should be reground. If this is the case once we have proven the material in the circuit, it will take priority over the zinc.

regrinding of coarse particles in an industrial flotation circuit. The addition of collector (BX) has a significant effect on the flotation response of chalcopyrite in the scavenger bank. The reconstructed recovery-time curve (combine products) is greater than that of the rougher tailings (scavenger feed) prior to reagent addition.

Classified slurry from the grinding circuit is dewatered in a flotation feed thickener from where feeds a three stage copper–lead–zinc sequential flotation circuit. The copper flotation section produces a copper concentrate through two stages of flotation as shown in Fig. 1. Flotation reagents are added through the conditioning tank, TKF2.

Originally developed in Canada in the 1960s as cleaning cells, this type of cell has become common in the flotation circuit of new plants, as both roughing and cleaning cells with diameters up to 4 or 5 m.
Effect of regrinding and pulp aeration on the flotation of ...
In flotation, regrinding is used to increase the liberation of value minerals, such as chalcopyrite, from gangue minerals. As a result of the significant decrease in particle size following regrinding, flotation efficiency is generally worst.
Froth flotation - Wikipedia
Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
Development of a Pyrite Regrind Circuit at Telfer Gold ...
The addition of an intermediate flotation stage ensured that the regrind circuit will improve overall recovery while at the same time reducing operating costs. Without the addition of a flotation stage, the additional reagent consumption from regrinding alone would be prohibitive towards increasing recovery.

Regrinding rougher flotation concentrates is typically used to liberate valuable minerals from gangue prior to the cleaner separation stage in processing of low grade ores. Compared to the rougher flotation after primary grinding, it is usually more challenging to achieve a satisfactory
