Chromite is a mineral whose main components are oxides of iron, magnesium and chromium: (Fe, Mg)Cr2O4, a type of spinel.For the processing of chrome ore, there are various methods such as gravity
Flotation recovery of chromite as a function of pH at constant SDS concentration 1 x 10 4 M is shown in figure 2. The four separate curves of the figure demonstrate the effect of aging of dry
In the beneficiation of chromite ore, we can use a medium magnetic machine to remove the magnetite, and then use a strong magnetic machine to recover
Deslimed chromite ore was floated at pH 1.5 to 5.5 using a longchain fattyacid collector and soluble fluoride ions as a silicate depressant. The Havens method was later modified slightly to permit
Only a very small amount of minus 200mesh material was present in the ore. The procedurefor flotation of chromite from the Pioneer mine sands recorded in Table 8 was
Odisha state is the major reserve of the chromite ore. Due to the extensive applications, highgrade chromite ore is getting depleted day by day. Now it is a challenge for the industry to utilize these lowgrade ores and tailings. Several attempts were taken to upgrade the lowgrade chrome ores and tailings using different gravity separation

During the beneficiation of chromite hosted PGE’s by froth flotation, chromite represents the principal gangue mineral. This is particularly true for the UG2 main seam. An excess of more than 3% in mass of chromite in the PGM concentrate is known to result in significant problems in the downstream processing and extraction of PGEs.
The latter technique has been developed in continuous flotation columns or in other pilot or industrial devices for processing of UG2 ore in South Africa [5, 16 18] to remove the major chromite
angle [3, 5, 6]. Wilfley table has been used to recover celestite ore [7] and also for the beneficiation of low grade manganese ore [8]. Significant research effort has been focused on recovery of chromite values from the plant tailings which need to be focused on mineral conservation, utilisation and environment protection point of view [9].
The fact is embodied in that chromite resources in these two countries accounted for 95 of the amount of global chrome ore resources resourceAccording to reports of the latest data South Africa Kazakhstan and India chromite total outputfigure out 13709000t which accounting for about 842 of chromite total output in the worldSouth Africa.
Only a very small amount of minus 200mesh material was present in the ore. The procedurefor flotation of chromite from the Pioneer mine sands recorded in Table 8 was as follows: 1. Sands as received were pulped with tap water to about 50 percent solids and an emulsion of oleic acid stabilized with "Emulsol X1" was added until flocculation
In South Africa, chromite is one of the main gangue constituents of especially UG2 ore, making up to between 20 and 60% by mass of the ore (cf. Figure 3). Although the main minerals targeted in flotation are generally the base metal sulphides, viz. pyrrhotite, pentlandite, and chalcopyrite, a certain amount of chromite reports to the

Chromite is an important strategic mineral usually associated with other gangue minerals, mainly silicates. The selective flotation of chromite minerals of any chromite ore have some difficulties due to dissolved cations from gangue minerals. By this work, selective flotation of various chromite ores were studied to determine some of the features of flotation.
Chromite ore is the only commercial source of chromium in the metallurgical industries [1]. It occurs as a chromium spinel, a complex mineral containing chromium, iron, aluminium and magnesium in changeable proportions depending upon the deposit [2]. Chromite deposits can be estimated using geostatistics and geotechnical methods [3,4].
The Bushveld Complex of South Africa contains three of the most important platinum deposits in the world namely the Merensky Reef, the Upper Group Two (UG2) chromitite reef and the Platreef. These three ore bodies are principally beneficiated by froth flotation. During the beneficiation of chromite hosted PGE’s by froth flotation, chromite
The mines, in upgrading the chromite content of their ore, produce a tailings stream that contains the majority of the PGMs of the ROM chrome ores. It is these chrome ores with elevated levels of PGMs that are treated. This is followed by flotation banks comprising 10 cleaner and five recleaner cells that take the concentrate recovery
the flotation medium per ton of ore in the serpentine flotation step, while 0.6 pound of amine collector is added to the medium in the chromite flotation step. From an ore containing 36.0% Cr2O3, a flotation con centrate was obtained containing 45.4% Cr2O3 repre senting a chromium recovery of 87.0%. Assessment of
levels using Denver flotation cell in order to investigate the collector performance in a basic medium. The experiments were conducted at two different test runs of slightly basic solutions of pH 8.5 and 9.0. The results of both fresh ore and floated ore samples were analysed using XRF. Although Black mountain ore contains small quantities
Only a very small amount of minus 200mesh material was present in the ore. The procedurefor flotation of chromite from the Pioneer mine sands recorded in Table 8 was as follows: 1.
