Characterisation And Pre-Concentration Of Chromite Values ...

Classification is a method of separation of fines from coarse particles and also lighter particles from heavier particles. The conventional classifiers, such as, hydrocyclone or mechanical classifiers, decreases the efficiency of the grinding and concentration circuits due to their imperfect separation. In the process of improving the efficiency of classification, a device that has been ...

Statistical Techniques For The Classification Of Chromites ...

Statistical Techniques For The Classification Of Chromites ...

The techniques used included nearest-neighbour analysis, CART (classification and regression trees) and MARS (multivariate adaptive regression splines). The results show that both CART and MARS approaches can correctly discriminate kimberlite/lamproite chromites from UML/'greenstone' chromites at levels near 90%.

Fusion Of Chromite Ore Using Sodium Phosphate Salt As …

Fusion Of Chromite Ore Using Sodium Phosphate Salt As …

Apr 05, 2021 In hydrometallurgy, fusion techniques are considered key in the processing of chromite ore. Salts containing easily ionized elements are often used as flux, which results in solutions with complicated matrices. A matrix correction approach was developed to remove sodium and phosphate ions from a solution obtained from the fusion of chromite using sodium phosphate salt as flux. The …
