Machine vision is widely used for monitoring of froth flotation plants to assist control operators on the plant. While these systems perform well in analyzing physical froth features, such as the color of the froth and bubble size distributions, research has continued to focus on their use in automated control systems, which are still in the development

Abstract. Copper ore mining and processing release hazardous post-flotation wastes that are difficult for remediation. The studied tailings were extremely rich in Cu (1800 mg kg -1) and contaminated with Co and Mn, and contained very little available forms of P, Fe, and Zn. The plants growing in tailings were distinctly enriched in Cu, Cd, Co
