Flotation of Chromite Ore

05/06/2017  Flotation of Chromite Procedure. Bench-scale flotation tests were performed on chromium ores using a Denver laboratory flotation machine. Locked-cycle flotation tests were performed on the gravity concentrate using both the Denver laboratory machine and a larger Denver No. 8 machine. The latter machine was used to prepare large samples of low-silica flotation

(PDF) Flotation of chromite and serpentine

Flotation of chromite, based on surface phenomena, has been extensively investigated for the recovery of fine particles in the range 25-100 µm [10, 11]. In a previous study [7], flotation

Chrome Ore Beneficiation Process Chromite Processing ...

The chrome raw ore is a flotation tail ore, which is mainly formed in the chromite, and the chromite is the target recovering mineral. The dissociation degree of ferrochromium ore is low, and it has a weak magnetic property. First of all, magnetic separation processing to separate chromite. Besides, the grain size is fine, so there is no need for grinding, the grading result shown in the below.

Flotation of chromite and serpentine - ScienceDirect

15/06/2007  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 obtained difference in results with the two modes ...

FLOTATION BEHAVIOR OF SUDANESE CHROMITE ORES

Figure 2 shows the chromite flotation recoveries as a function of various dosages of oleic acid at different pH values. The flotation results revealed that increasing the oleic acid dosage up to 3kg/t increases the recovery. Because the pH of the medium is an important factor in flotation, its effect was investigated. The higher flotation recoveries were attained at pH11, and this may be due ...

Chromite - an overview ScienceDirect Topics

Problems associated with chromite are minimized by (i) rejecting chromite to tailings during flotation; and, (ii) minimizing the internal recycle in the smelter complex of high-chromium materials, such as converter slag, to the smelting furnace. These procedures permit steady, efficient smelting with between 2 and 3% of chromite in the feed concentrate. View chapter Purchase book. Read full ...

Chromite Beneficiation Process

19/03/2017  Chromite Process Summary This flowsheet is very effective due to the ability to remove the high grade chrome with very little grinding on each pass through the mill. In this way, grinding takes place with a large number of small reductions followed by immediate removal of the liberated chrome into a high grade concentrate.

PAME for froth flotation of chromite

Batch flotation procedure The flotation . Get price → flotation of chromite ore atavloeren . Chromite is beneficiated by froth flotation with an amine reagent. The ore is ground to 210 micrometer, pulped to 29 pct solids, acidified to ph 2.5 With h2so4, and floated with 0. 1.0 Lb amine collector/ton of ore.Thus, chromite ore was ground to mesh, deslimed to >30 micrometer, and pulped to 24 ...

Development of PGMs and Chrome Extraction Circuit from UG ...

in the middle of the flotation circuit in order to benefit the increased in PGMs recovery from secondary circuit by lower tonnage to the mill, hence more residence time and better grindings. This mine recovers PGMs loss of below 1% recoverable from the chromites. Barplats mine is a PGMs mine located on the Bushveld complex in South Africa, the main ore body is the UG-2 chromitite layer. The ...

Application of fundamentals in optimizing platinum ...

The entrainment of chromite to the UG2 flotation concentrate adds another challenge to the concentrator operator in that limits are placed on the amount of chromite allowed. Excess chromite in the concentrate results in the build-up of highly refractory chromite spinel layers in the furnaces, thus affecting furnace operation and furnace availability and increasing operating costs (Philips et ...

Copper Nickel Flotation

The flotation procedure used was to condition 600 grams of ground ore pulp for 3 min, using collector at the rate of 0.1 lb/ton; add 1 drop of MIBC, condition for 1 min; and then float (5 min) to produce a rougher concentrate and tailings. The rougher concentrate was cleaned once to produce a final concentrate and a middling product. These middlings were weighed (while wet), sampled, reground ...

Five Chrome Extraction Process to Teach you the Chromite ...

Flotation process. At present, we can use the flotation process to recover the chromite with fine grain size (-100um) after the gravity separation. The results show that Mg2+ and Ca2+ can inhibit the chromium ore, and the inhibition of Mg2+ is influenced by the type of anions in the slurry. Therefore, after knowing the cationic behavior in the pulp, we can choose the appropriate pulp PH value, reagents

•Chromite and PGM+Au grade targets can be successfully achieved through reagent optimisation •Effect of solids and frother concentration on entrained mass is significant •Increased depressant may result in an increase in chromite grade •Selection of depressant dosage points is important •Optimisation of reagent suite by starting from scratch

Figure 1 from THE FLOTATION OF SOUTH AFRICAN

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. Different chromite ores from South Africa were made flotation using the anionic collector, A825 (petroleum sulfonate), after
