Öğe Mechano-activated surface modification by stirred milling with metallic soaps and fatty acid(TMMOB Maden Muhendisleri Odasi, 2017) Toraman, O.Y.; Kose, H.; Bitirmis, B.This paper investigates the surface modification of calcite (CaCO3) from the Ni?de region of Turkey with sodium oleate (SO), sodium stearate (SDS) and stearic acid (SA) complex as modification agents, which are incorporated into the calcite with dry ultra-fine grinding in a laboratory stirred mill (750 ml). The effect of surface modification is evaluated by a floating test, which is characterized by the active ratio, colour properties and oil absorption. The results indicate that the hydrophilic surface of calcite becomes hydrophobic after the incorporation of SO, SDS and SA by dry stirred milling.
