Chrome Ore Beneficiation Process | Chromite Processing - JXSC ...

3.1 Chrome magnetic separation process The chrome 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.

Chrome ore process - Yantai Jinpeng Mining equipment ore ...

Chrome ore process Gravity separation is the mainly process for chrome processing ,sometimes the chrome concentrate will be separated by low intensity magnetic separation or high-intensity magnetic separation for a second processing that`s to improve the grade of the chrome .Several ores can use flotation or flocculation flotation process .


The flotation process is typically conducted by adding 0.5 to 5.0 pounds fatty acid 0.1 to 10.0 pounds soluble fluoride ion and 1.0 to 11.0 pounds sulfuric acid per ton of ore to the aqueous treatment medium containing the chromite ore.

Chrome ore process - Yantai Jinpeng Mining equipment ore ...

Introduction. We can use gravity separation flotation separation and magnetic separation for chrome ore processing according to its analysis report and test report decide finally the proper solution . The fine grain after crushing will be transport to classifier spiral according the different gravity they are separated washed classified in different speed .After jig and shaking table washing transferred to sluice to separate then into flotation or magnetic separator the ...

Chromium Ore - an overview | ScienceDirect Topics

Chromium is extracted from its ores by two processes. In the alkaline process the finely ground ore is roasted with Na 2 CO 3 under oxidizing conditions at 1100 °C. The sodium chromate is leached from the calcine.

Chrome Ore Chrome Recovery Chrome Mineral Chrome Mining ...

Most chrome ore must be processed by the chrome ore processing plants. the mainly chrome ore beneficiation method is gravity separation. So the mainly used chrome ore concentrating equipments are ore washbox (sometimes it is called jigger) concentrating table spiral classifiers etc.

Flotation of Chromite Ore

The general flotation method was developed by Havens. Deslimed chromite ore was floated at pH 1.5 to 5.5 using a long-chain fatty-acid collector and soluble fluoride ions as a silicate depressant. The Havens method was later modified slightly to permit flotation without preliminary desprm.

1 Froth Flotation – Fundamental Principles

After carrying out a froth flotation separation the products are as shown in Table 1. Using this data calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery or % Yield (e) Enrichment Ratio Table 1: Grade/recovery performance of a hypothetical copper ore flotation process.

flotation process of chromite ore

May 16 2019 Chrome process equipment is wet type strong magnetic separator and spiral chute (chrome spiral plant) of gravity separator. 3 Experimental results and discussion 3.1 Chrome magnetic separation process. The chrome ore is a flotation tail ore which is mainly formed in the chromite and the chromite is the target recovering mineral.

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

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.

How to process Chrome ore with Mining equipment? - JXSC Machine

The ore dressing technology of chrome ore mainly has Gravity separation process the chrome ore mining equipment are jig separator shaking table spiral classifier centrifugal concentrator and spiral chute and sometimes the concentrate will be selected by weak magnetic separator or high intensity magnetic separator to further improve the grade of chromium concentrate and the ratio of chromium iron.


There are two general types of methods for separating chromium ore (chromite) values from associated gangue minerals by froth flotation techniques. In the first method chromite ore which has been deslimed is subjected to flotation at a pH of 1.5 to 5.5 with a long chain fatty acid collector as reported by Havens (1946). The

Chromium Mining | Processing Equipment | Flow Chart | Cases ...

1. Large chrome ore for primary crushing are fed into the jaw crusher by Plate feeder and are reduced to 8 inches or smaller. After first crushing the material will be transferred to cone crusher by belt conveyor for secondary crushing; the crushed chrome ore stone will then transferred to vibrating screen for classifying.
