Tailings.info What Are Tailings? - Their nature and production
The five basic types of reagent used in froth flotation recovery include collectors, frothers, depressants, activators and modifiers. When designing the processing plant, the types and quantities of reagents used should be considered together with any depressing requirements to lessen environmental impacts in the tailings streams (Ritcey 1989).
3 Takes on Tailings Technology | E & MJ
This technology enabled the expansion of copper supply at an affordable price. Despite the great success of conventional flotation, it is known and reluctantly accepted that this technology is very poor for extracting target minerals outside of a narrow particle size range. Typically 5%-15% of recoverable copper is lost due to this inefficiency.

Tailings and tailings ponds | Codelco Ecuador
Tailings and tailings ponds Rainfall is a critical factor in how effectively mining waste can be contained. When copper is separated from the rock we are left with tailings. Tailings are fine waste rock particles suspended in water.
Heavy metal and nutrient uptake in plants colonizing post
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, Ni, and Pb, and the concentration of copper …
