As an effective measurement indicator of bubble stability, bubble size structure is believed to be closely related to flotation performance in copper rougher flotation. Moreover, reagent dosage has been shown to significantly influence the bubble size [17]. Frothers are known as flotation chemicals that have the greatest effect on bubble size.
