Recovery of Chromite From Plant Tailings By Falcon Concentrator

摘要

The objective of the present study was to investigate to recover chromite from Sivas -Kangal- ?am?zü chromite plant tailings assaying 4.95% Cr2O3by using a Falcon Concentrator. By using L40 type Falcon Concentrator a concentrate assaying of 13% Cr2O3 with 63.03% recovery was obtained from ?am?zü plant tailings at 30 G rotor rotation speed with -150 micron feed grain size at 40 kPa water pressure. It was found that the degree of liberation is an important parameter for Falcon Concentrator. At -600μ, -500μ and -300μ grain sizes by increasing rotor rotation speeds the grades of chromite decrease and recoveries are increase.
