and cationic had stronger adaptability in the pulp, which reduced the consumption of the sulfurizing agent and improved flotation index. So far, researches about the combined collector for copper oxide... direction. This implies that the cationic collector DDA ionizes , and then it is adsorbed on the negatively charged mineral surface through electrostatic adsorption. In addition, it should be noted......
on gangue recovery in froth was investigated. Effects of frother type and collector dosage on flotation performance were tested at pH 10. The results were evaluated statistically by two-way analysis... in the presence of Na-oleate as collector; entrapment and slime coating were also proposed as recovery mechanisms in minority. Degree of gangue-entrainment in froth product increases by reduction......
between cationic surfactants and acids in crude oil and wettability alternation YAO Tong-yu1,LI Ji-shan2 ( College of Petroleum Engineering, China University of Petroleum, Dongying 257061, China.... Meanwhile the contribution of mass transfer on the wettability alternation of carbonate was also studied. The experiments show that ion-pairs between carboxylic acids in oil phase and the cationic......
FLOTATION SEPARATION OF WOLLASTONITE FROM DIOPSIDE袁继祖,曹明礼,袁楚雄摘 要:<正>The floatabilities of single mineral samples of wollas-tonite and diopside have been studied with addition, of a cationic collector,dodecyoamine hydrochloride (DDA·HCl) , and,modifiers. A mixture oftwo minerals was successfully separated,when DDA·HCl and tannicacid (as depressant......
