Most of the copper in the world is produced by processing sulfide ores by flotation to obtain copper concentrates and their subsequent processing using pyrometallurgical technologies A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial.

Sulfidizing Behavior of Complex Lead-Silver Ore: A
Although some silver ores exist in an elemental state or a combined state, most of them can be found in either lead or both lead and zinc concentrates, or even distributed in gangue. In this study, the An effective flotation process was proposed for selective recovery of elemental sulfur from an oxygen pressure acid leaching residue of zinc sulfide concentrate. The optimal closed flotation process is: one-time blank rougher, two-time agent-added roughers, and two-time cleaners, and the selected collector and inhibitor were Z-200 and Comprehensive Recovery of Oxygen Pressure Acid Leaching Residue of Zinc

Copper, Lead and Zinc Smelting and Refining ILO Encyclopaedia
Zinc concentrate is produced by separating the ore, which may contain as little as 2% zinc, from waste rock by crushing and flotation, a process normally performed at the mining site. The zinc concentrate is then reduced to zinc metal in one of two ways: either pyrometallurgically by distillation (retorting in a furnace) or hydrometallurgically by Flotation of Copper–Gold Ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper concentrate grade and copper and goldFlotation of Gold and Gold-Bearing Ores ScienceDirect

Mineralogy and Innovative Flash Flotation Separation of Cu-Pb
Pyrite in complex metallic ore is a widely distributed sulfide on earth, commonly associated with copper, lead, and zinc sulfides, as well as gold and silver [1,2].The production of separate concentrates from ores containing economic amounts of copper, lead, and zinc is complicated [], especially for ores with high pyrite content 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 importanceA Review of the Flotation of Copper Minerals ResearchGate

Froth flotation
His "Bradford washer," patented 1870, was used to concentrate iron, copper and lead-zinc ores by specific gravity, but lost some of the metal as float off the concentration process. The 1886 patent was to capture this "float" using surface tension, the first of the skin-flotation process patents that were eclipsed by oil froth flotation.Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are The Challenges and Prospects of Recovering Fine
