anionic collector alone. Also, fluorite flotation could be improved by using effective depressants when fatty acid is used as collector. For example, acidized sodium silicate was reported to depress calcite strongly in preference of fluorite at ambient temperature, leading the fluorite flotation to be achieved at a lower temperature [4].

1 Froth Flotation – Fundamental Principles

Froth flotation is a good example of an engineering "system", in that the various important parameters are highly inter-related, as shown in Figure 1. It is therefore important to take all of Chemistry Components Collectors Frothers Activators Depressants pH Equipment Components Cell Design Agitation Air Flow Cell Bank Configuration

Fluorite flotation tests were carried out with the actual and new schemes. Fig. 2 showed the photographs of the tailing slurries after being settled for 96 h from the flotation test with the actual scheme and being settled for 2 h from the test with the new scheme.With the actual scheme (Fig. 2a), 96 h of sedimentation did not produce clarified water in the tailing slurry, indicating a very ...

FROTH FLOTATION | Wetting | Chemical Compounds

FROTH FLOTATION involves three different phases- solid (fine ore powder), liquid (water) and froth. The process of separation of mineral includes three important mechanisms : 1. TRUE FLOTATION, i.e., selective attachment to air bubbles. 2. ENTRAINMENT in the water which passes through the froth. 3.

Froth Flotation - an overview | ScienceDirect Topics

Froth Flotation. Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material [17,34]. From: Advances in Colloid and Interface Science, 2005.

(PDF) Reverse Flotation Separation of Fluorite from ...

Fluorite (CaF2), as an important strategic mineral source, is usually separated from calcite by the common froth flotation method, but this separation is still not selective enough.

fluorite. These results were achieved with a very simple flow one stage of oleaner flotation. It seems obvious that sheet which consisted of grinding, rougher flotation and only additional stages of cleaner flotation combined with depr?ssind the gangue minerals should produce a commeroial grade fluorite …

Froth Flotation - Metallurgist & Mineral Processing Engineer

A run-away is a frightening experience for a novice flotation operator. Froth begins to flow from the surface of the cells at such a rate that launder water sprays cannot break down the froth and it then begins to overflow the launder depositing on the sump floor. Even by dropping the cell level, the froth continues to flow and cannot be stopped.

COPPER Copper production - TU Delft

1. Beneficiation by froth flotation of ore to give copper concentrate (Optional partial roasting to obtain oxidized material or calcines) 2. Two-stage pyrometallurgical extraction 1. smelting concentrates to matte 2. converting matte by oxidation to crude (converter or blister) copper 3. Refining the crude copper, usually in two steps

Froth Flotation | PDF | Chemistry | Materials

Froth flotation was invented in the early 1900s in Australia by C.V. Potter and around the same time by G.D. Deprat. The process was adapted and applied to a wide variety of materials to be separated. In the 1960s the flotation technique was adapted for deinking recycled paper.

TECHNICAL NOTES 9 FLOTATION - mineraltech.com

froth layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.
