CONCENTRATING OF FELDSPAR FROM Al-SAMAWA SAND DUNE

Abstract

This study was carried out to determine the possibility of upgrading feldspar from Al-Samawa sand dune deposit containing about 2 % Na 2 O and 1 % K 2 O. Two samples from the same location was tested by screening, employing, washing and disliming followed by magnetic separation then froth flotation by tallow amine acetate as a collector with poly propylene glycol and Ethyl diamine tetracetate (EDTA). The experimental results shows that a concentrate of commercial grade can be obtained in percent 5.54 % Na 2 O and 2.41 % K 2 O with a recovery of about 76.2 % and 77 % respectively.
