Analysis of emulsified ZS reagent effect on flotation results of lignite semi-coke and its mechanism

in order to inprov fotation efe c of inite semi-coke,based on the proximate analysis element analysis and infrared spectrum analysis on the lignite semi-coke and the measurement on the pore diamete distributon of the linite semi-coke the emusfed 2sS reagent would be appied to the fotation experiment on the lgnie semi-oke and the foatation effcts of the conventional reagent Noa. 0 diesel kerosene and Zs reagent were compared.The experiment resuts showed that ae r the foatation,.the ash conten of the ligntie semi-coke could be reduced in some degree and when the conventionalreagent applied to the ficatation of the li ntesemi- coke the reagent consumnption would be high.Nhen the ash content ofthe clean coal frm the fioatation was closed to.the applcatin of the emuisfied Zs reagent could save the reagent volume by 79% and the reagent consumpton would be reduced below 1 kg / t.The clean cal yeld and ficataton perect idex wouda be improved anda preliminary discussion was conducted on the collection mechanism of the emulsified Zs reagent.
