  Flotation Reagent, Flotation Agent, Flotation Reagents

  Several-time dosing: Add the flotation reagents in several times along roughing, concentrating and scavenging. Generally, add 60%~70% of the total amount before the flotation stage, and the rest of reagents is added to the appropriate locations in batches. Application: Oxidizing, labile and reactive reagents, such as xanthate, sulfur dioxide ...

  Handbook of Flotation Reagents | ScienceDirect

  The reagent scheme used in the treatment of lead–zinc ores varies considerably and depends on the nature and mineralogy of the ore. In most cases, NaCN–ZnSO 4 depressant system is used with xanthate + dithiophosphate collectors. These reagent schemes are normally employed for treatment of carbonatite and coarse-grained massive sulfides.

  Processes | Free Full-Text | Intelligent Setting Method of Reagent ...

  202053 · It is well known that the change of the reagent dosage during the flotation process will cause the froth image to change continuously with time. Therefore, an intelligent setting method based on the time series froth image in the zinc flotation process is proposed. Firstly, the sigmoid kernel function is used to estimate the cumulative distribution function …
