 — This study conducted and presented a novel approach for separating copper, aluminum, and plastic content from spent LIBs by froth flotation to tackle these drawbacks. In this paper, a feasible flow sheet for the successful recycling of LIB was presented, although the main target was the recovery of Cu and Al.

Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash.

 — Chalcopyrite, the most abundant copper sulfide in nature, is extracted from deposits and concentrated mainly by froth flotation operations. It is common to apply collectors that hydrophobize their surface and generate greater adhesion efficiency to the bubbles to achieve industrially sustainable yields.

 — This group of frothers is widely used in the flotation of zinc, lead and copper minerals significantly improving the flotation efficiency (Numprasanthai et al., 2013, …

 — Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (e.g., via froth flotation). Figure 1: Chalcopyrite extracted from Zacatecas, Mexico. from Rob Lavinsky (iRocks.com) under a CC-BY-SA-3.0 license.

 — 1. Introduction. Today, the flotation method, in which many parameters are effective, remains one of the most significant enrichment methods. According to Nagaraj [1] anything put into the flotation cell affects froth characteristics, as well as physical and operational parameters. The identities that are described as collectors, frothers and …

 — The present work focuses on recovery of copper value by froth flotation from the copper smelter slag. The QEMSCAN results revealed that copper is present in sulphide form in fayalite (iron–silicate) matrix and very poorly liberated and require fine grinding. The present investigation has studied the respective roles of sodium iso-propyl ...

 — Froth flotation is a widely used metallurgical technique which is used in different fields like mineral processing, waste water treatments etc. ... (Fe), copper (Cu) etc. Often before roasting, the ore (generally sulfide ores) is partially purified using another important technique which is called froth flotation and it is the

 — Conditions of operation of froth-flotation. Froth-flotation is in general effective only on ores ground to pass 0.3-mm. aperture or less and the agitation-froth and bubble-column processes are most effectively practiced when the bulk of …

 — 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 separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …

 — After froth flotation, each product of froth flotation recovered (froth and depressed) were allowed to settle for 24 hours before decanting, filtered, dried at a temperature of 105 °C and weighed

 — The paper is about the froth flotation process and its application. It is a metallurgical process for the extraction of metals in a pure state from their ores: especially for sulfide ores.

 — The ores are concentrated through froth flotation in the form of copper-sulfide or copper-iron-sulfide minerals (e.g. chalcopyrite, chalcocite and etc.), which are then melted in a high-temperature reheating furnace (± 1250 ℃). ... The floatation of CuS increases when its surface is slightly oxidized, which is attributed to Reaction (3) and ...

 — And it is a type of hydroxy copper carbonate, which is formed by oxidation and chemical precipitation of primary copper sulfide mineral [3]. As we all know, froth flotation is considered to be an effective method for enrichment and separation of copper oxide due to its simple process, cost effectiveness and environmental friendliness [4] .

 — Several attempts have been done, aiming to recover copper from flotation tailings through mainly acid leaching [17], and froth flotation [4].Using the latter, the recovery of copper through reprocessing of tailings has been studied both in the laboratory and on the pilot scale with an emphasis on the concentration of reagents and a pre-economic …

 — The ground copper slag is then subjected to froth flotation, wherein various reagents are added to facilitate the flotation of valuable constituents and the simultaneous removal of undesirable impurities. The flotation concentrate is then subjected to roasting in the presence of additives to transform it into a product amenable to leaching.
