'a process for enriching chromite values of ultrafine particles in chromite tailings by selective flocculation technique to produce higher grade of cr2o3 concentrate'

摘要

The invention relates to a process for enriching chromite values of ultrafine particles in chromite tailings ( 37 μm) by selective flocculation and desliming technique to produce higher grade of Cr2O3 concentrate, the process comprising the steps of grinding as received chromite tailing samples by a ball mill to generate particles of size to below (150 μm) size for better liberation; subjecting the grounded particles for desliming by a hydrocyclone; subjecting the underflow product from the deslimed hydrocyclone to grinding below 37 micron size particles and using as a feed for selective flocculation process.
