Abstract

Abstract: The material properties of flotation feed coal slime from Sima coal plant with soaking and not were analyzed. Step by step releasing test and flotation rate test for feed coal slime with different soaking time were conducted and flotation dynamic models were built. Flotation effects with different soaking time were compared. The results showed that hydrogen bondings between water and oxygen-containing functional groups on the coal surface appeared and the coal surface was oxidized, the coal particle’s hydrophily increased but the floatability decreased. The flotation effects will get further deterioration with the strengthened entrainment and slime coating by soaking.

Key words: flotation, soaking, oxide, slimecoating, floatability
