Hi, welcome to visit!
copper produced in the United States originated from flotation (Daniel E. Edelstein, Copper Commodity Specialist, U.S. Geological Survey, written commun., March 20, 2012). Copper sulfide ores must be concentrated before they can be economically transported to a smelter.
The largest source of copper supply worldwide comes from copper produced through flotation processes. It is estimated that more than 82% of primary copper production comes from concentration by flotation processes. In Peru, the latest mining megaprojects have been concentrator plants (Cerro Verde, Las Bambas, Constancia, Antapaccay, and so on).

The initial beneficiation stage of these copper and molybdenum minerals is commonly using flotation 3,5. Flotation is widely used in mineral processing to separate minerals based on the difference in surface hydrophobicity. In the conventional flotation circuit, the copper sulphide minerals are collected as a froth product.
Micro-flotation tests poorly respond to the flotation with copper sulfate as the activator, leading to a bad beneficiation (low concentrates The micro-flotation of the high-iron marmatite particles grade and recovery). In addition, copper sulfate as an acti- was performed in a Hallimond flotation tube with nitrogen vator acts in a strongly ...
Copper slag wastes, even if treated via processes such as flotation for metal recovery, still contain heavy metals with hazardous properties posing environmental risks for disposal. This study reports the potential use of flotation waste of a copper slag (FWCS) as iron source in the production of Portland cement clinker.
A novel flotation promoter used in the concentration of copper bearing ores for the efficient selective flotation of copper values, including chalcopyrite, with suppression of iron pyrites the promoter comprising a sodium sulfate of an aliphatic hydrocarbon having a carbon chain in excess of 12 carbons and chemically combined with at least one mole of the C2-C3 alkylene
One of the primary sources for molybdenum is the by product recovery of molybdenite by flotation from bulk copper/ molybdenum concentrates. For this flotation system a number of different reagents are used, including alkali sulfides, Nokes reagents, cyanides, chemical oxidants, and/or thermal treatment

copper is growing constantly , the need to develop processes and technologies to treat copper resources from additional sources such as mine tailings, low grade deposits, industrial wastes and deposits with high impurity levels such as As and Sb will continue to increase 4. Flotation mechanisms of tennantite-tetrahedrite series
Jul 20, 2021 The flotation process has a relatively simple flow and has the strong adaptability to the change of ore grade. Application The flotation process is generally used for copper-lead-zinc sulfide ores with simple composition, high raw ore grade, large difference in floatability of useful minerals and coarse disseminated particle size.
RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan M.S., Department of Mining Engineering Supervisor Prof. Dr. Mustafa mit Atalay December 2014, 65 pages The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching.
the thickener supply from flotation cells. Before flotation process, the ore particles should be smaller wherever fine particles appropriate for froth flotation. Comminution and flotation are the high energy consuming stages for copper ore, since every piece of ore-regardless of grade-must be crushed, ground and processed. Froth flotation
Flotation of porphyry coppermolybdenum ores (theoretical considerations) Molybdenite-bearing copper sulphide ores are typically beneficiated by froth flotation techniques in two stages. The first stage, commonly known as the copper circuit, produces a bulk copper sulphide molybdenum sulphide concentrate. The second stage

An effective processing method has not been found to recover copper and cobalt from this ore, which has been stockpiled for 40-45 years in the idled plant. It was established that recovery
Jul 27, 2021 Coarse-particle flotation applied to copper sulfide ores. Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.
The ore is a sulfide copper ore containing heads of approximately copper 0.45, iron 3.5, molybdenum 0.006, and zinc 0.06 per ore sample. Prior flotation of this ore has employed, in the flotation cell, the addition of pine oil as required to optimize froth, ordinarily resulting in a total pine oil concentration of about 0.24 lb./ton.
