به خواندن ادامه دهیدSrdjan 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.
