Froth Flotation Froth flotation is one of the most versatile and flexible of all mineral separation processes. Reasonable results are fairly easy to obtain but outstanding performance from a circuit requires constant attention and good understanding of the process and ore. Some of the variables that affect the operation and
This data on chemicals, and mixtures of chemicals, commonly known as reagents, is presented for the purpose of acquainting those interested in froth flotation with some of the more common reagents and their various uses.. Flotation as a concentration process has been extensively used for a number of years. However, little is known of it as an exact science, although, various …

chromite while PGMs mostly occur as sulphides with oxides and sulphides exhibiting different behaviour in the presence of flotation reagents. It has been reported [9] that a PGM industrial froth flotation concentration circuit was modified by including a chrome extraction plant in its middle thus reducing

Froth Flotation (Sulphide & Oxide) Froth Flotation (Sulphide & Oxide) To participate in the 911Metallurgist Forums, ... I wonder if flotation is used for chromite processing at all. Can anyone name any producing plants where flotation is used from chromite/chromite slimes? ...
Calculated results can be used to investigate transport phenomena at the pulp–froth interface, to estimate pulp recoveries and froth recoveries. The flotation of chromite in a 15-cm diameter ...
This provides a clear indication that depressants play little role in the flotation of chromite other than possibly affecting the behaviour, i.e. stability, of the froth by reducing the mass of solid particles reporting to the froth. The chromite grade of the concentrate was hardly affected by increasing the froth height from 5 cm to 60 cm.

flotation behavior of sudanese chromite ores 1 Assiut University. This study is concerned with the processing of low grade chromite ores, The flotation process is typically conducted by adding 0.5 to 5.0 pounds fatty acid, 0.1.
ABSTRACT Chromite samples from Africa, Brazil, Philippines and Russia were investigated through electrophoretic mobility and method of Mular and Roberts measurements. Chemical composition, lattice constant and specific gravity were determined. ... Emphasis is placed on froth flotation as the major technique for the beneficiation of Cu-Co minerals.
depressant dosage on the recovery of chromite during flotation. The DOW 200 frother was added at a concentration of 30 g/ton to create a suitably stable froth phase where the valuable minerals could be collected for further processing. Batch flotation procedure The …
Froth flotation was used to upgrade this chromite ore. Oleic acid was used as collector. Several operating parameters influencing the floatability of the Sudanese chromite ores were investigated. These include the collector and depressant dosages, pulp pH, and conditioning time.
Alvarez-Silva et al. (2013), in the same comprehensive study of the flotation of UG2 ores, also studied the effect of froth height and superficial air rate on chromite recovery using a 2 m high laboratory scale column flotation cell operating in continuous open circuit mode.
The physico-chemical interactions among minerals such as olivine, chromite and serpentine; the most commonly present ions in solution such as Ca and Mg; and flotation reagents such as EDTA and oleic acid were investigated. The study was conducted via release tests, electro-phoretic measurements and microflotation of selected minerals coming from the Kukes deposit in Albania. The …
Calculated results can be used to investigate transport phenomena at the pulp-froth interface, to estimate pulp recoveries and froth recoveries. The flotation of chromite in a 15-cm diameter column serves as a case study to demonstrate the application of the calculation procedure.
The effect of copper sulphate on the zeta potential of chromite was also determined. It was found that collectors alone have an insignificant effect on the flotation of chromite whereas, in the presence of copper sulphate recoveries of above 60% were observed in mildly acid to mildly alkaline solutions decreasing 20% at a pH value of 10.
10% and secondly the high chromite content in the flotation concentrate leads to downstream smelting problems. This project was aimed at improving the recovery of platinum and reducing the amount of ...

The experiments were designed to investigate the flotation behaviour of chromite in UG2 ore with various frothers. Five frothers with different characters were selected to create different froth structures ().The three frothers (SF6005, SF6008 and SF9325) supplied by Senmin are proprietary blend frothers and their chemical nature is not known.
1.2.2 Froth flotation This method is commonly used to concentrate sulphide ores such as galena (PbS), zinc ... chromite, pyrolusite having magnetic property can be removed from the non magnetic siliceous impurities. The crushed ore is poured on to an electromagnetic
Gravity separation and froth flotation constituted the majority of the earlier mineral beneficiation work. The Bureau of Mines, U.S. Department of the Interior, devised a flotation technique for upgrading chromite in chromium ores and gravity concentrates.
Chromite–serpentine separation was performed applying the froth flotation method, in which chromite was concentrated in the concentrate and serpentine was enriched in the tailings. In preliminary tests, it was found that the modifier should be first added and the pulp conditioned, followed by the collector addition and new conditioning; the ...
In fact, the interlocked texture between chromite and the valuable minerals predisposes the PGM ores to an inefficient froth flotation. Studies on the froth flotation of PGM ores abound (Mailula ...
