7.1 INTRODUCTION. The adsorption mechanism of flotation collectors on mineral surfaces is a highly complex phenomenon. Even with today's scientific approach to mineral processing, there remain unresolved aspects with respect to collector adsorption. This can be best illustrated through some passages from contributing investigators.

About this site

Srdjan M. Bulatovic, in Handbook of Flotation Reagents, 2007 Processing characteristics of a massive sulfide ore. When using a conventional flotation reagent scheme and flowsheet, only a few of these ores respond (i.e. lime + NaCN + collector), giving extremely poor metallurgical results. The majority of these ores require a specific treatment process to achieve satisfactory metallurgical results.
