Abstract

In this study, experimental studies have performed to recover chromite from Eskiköy-Sivas chromite concentrator which is owned Bilfer Madencilik
ve Turizm A.Ş. Mineralogical and liberation measurement studies were performed, and it was decided to grind the feed to 100% finer than 300 µm.
Gravity concentration and wet high intensity magnetic separation (WHIMS) tests were performed. After grinding to -300 µm, -38 µm fraction which
cannot be recovered efficiently was removed. The studies were conducted on 300+100 µm and -100+38 µm fractions. After the beneficiation tests, it
was determined a circuit consists of spiral concentrator and shaking tables could produce a concentrate containing 48% Cr2O3 from the tailings having 6.54 % Cr2O3, with a 56% recovery.
