 — The metallurgical technique called flotation began to be implemented in mining projects in the late nineteenth and early twentieth centuries (1860–1905), which allowed the separation of metal sulphide minerals from gangue mineralogy or copper mine tailings. The flotation, also called physical–chemical concentration of minerals, allowed to ...

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).

 — Considering the price of copper in the world and the environment protection policy of China, a possible recovery of copper from tailings by flotation can be obtained. Download: Download high-res image (321KB) ... The chemical composition of the tailings was analyzed via X-ray fluorescence spectrometry using an Axios mAX spectrometer ...

 — The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of great commercial importance ...

 — The flotation tailings pond of the Bor Copper Mine poses a great ecological problem not only for the town of Bor but also for the surrounding soils and watercourses. Since the old flotation tailings contain about 0.2% of copper on the average, we investigated their leaching with sulphuric acid in the absence and presence of an oxidant.

 — The mineral composition of copper–cobalt ores is more complex than that of copper sulfides, and it is also difficult to discard tailing efficiently in primary flotation for the fine-grained ...

 — The possibility of selective Cu and Zn leaching from the sample of old pyrite tailings, which is one of the most widespread types of solid waste forming during non-ferrous metal production, using sulfuric acid solutions and water was studied. It was shown that water leaching provided selective extraction of Cu and Zn and comparatively low …
