Copper Oxide Flotation - Mineral Processing & Metallurgy
Alkyl hydroxamate can effectively recover well-defined oxide copper minerals (malachite, cuprite, etc.) Certain AS Cu species are not amenable to flotation with hydroxamates. Examples of these are: Cu-bearing goethite, cuprite finely disseminated in gangue matrix, and chrysocollas that have a very low copper …
Evaluate Oxide Copper Recovery by Flotation
If the idea is try to recover, by flotation, copper oxides that are located in the upper part of the deposit. According to geology department the main copper oxide minerals are chrysocolla and atacamite. There are small quantities of azurite and malachite. As far as I know, it is difficult to float chrysocolla.

RECOVERY OF COPPER FROM OXIDE COPPER ORE BY FLOTATION AND LEACHING Kiraz, Emirhan M.S., Department of Mining Engineering Supervisor: Prof. Dr. Mustafa Ümit 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.
flotation copper oxide - Froth Flotation (Sulphide & Oxide ...
Mahdi Radio Hill in Australia successfully used the Ausmelt reagent AM28 (an alkyl hydroxamate) to float mixed sulphide/oxide copper ore, increasing recovery from a low of 40 to 50% up to 70%. They used AM28 to replace sulphidisation of oxide minerals, in conjunction with standard sulphide collectors to recover sulphide minerals.
(PDF) RECOVERY OF COPPER FROM OXIDE COPPER ORE BY ...
The highest copper recovery of concentrate was found as 61.35% with 8.69% copper content. The concentrate with highest copper grade of 34.65% was obtained with only 26.98% copper recovery....
(PDF) Copper Recovery from Yulong Complex Copper Oxide Ore ...
The results showed that 74.08% Cu was recovered by flotation, while the average grade of the copper concentrates was 21.68%. Another 17.34% Cu was further recovered from the flotation tailing by...
A Copper Oxide Ore Treatment by Flotation - ResearchGate
In conjunction with Ausmelt Chemicals, Minto is currently investigating options to recover copper oxide and sulphide minerals using flotation by blending their primary sulphide ore with oxide ores....
Oxide Flotation Collector | Collector for Copper Oxide Ore
This good oxide flotation recovery was however associated with a large %Mass pull of 25% to 50% Oxflo was able to obtain almost 20% Ag Recovery at below 15% Mass. Both reagents appear to on the same Grade/Recovery curve. “Blue dots” are seemingly a continuation of the trend started by “red dots”. Cleaner Tests : This are Axis only data.
(PDF) A Review of the Flotation of Copper Minerals
Oxidic ore can be concentrated using flotation or, if it has a low acid demand, it may be economic to acid heap leach the stockpile. The recovery of these copper minerals by flotation or...
Copper Oxide - an overview | ScienceDirect Topics
The copper-oxide superconductors all contain CuO 2 sheets in which any apical Cu-O bonds perpendicular to a sheet are significantly longer than the in-plane Cu-O bonds. This structural feature signals full occupancy of the (3z 2 –r 2) orbitals of an e-orbital pair.The parent compounds of the superconductive systems contain all Cu II in the CuO 2 sheets, which leaves the in-plane (x 2 – y 2 ...
Flotation of mixed copper oxide and sulphide minerals with ...
In conjunction with Ausmelt Chemicals, Minto is currently investigating options to recover copper oxide and sulphide minerals using flotation by blending their primary sulphide ore with oxide ores. The blend used in this laboratory scale investigation was 70% sulphide ore and 30% oxide ore on a weight basis.
Treatment of Mixed Sulfide Oxide Ores of Copper
The oxide orebodies, in which the copper is present about half as sulfide and half as oxidized minerals, and where the recovery to be expected is 25 or 30 lb. per ton of ore, might well be treated first by the method used at New Cornelia, to recover the oxide copper, then reground and sent through the regular flotation operation.
AN INVESTIGATION OF COPPER RECOVERY FROM A …
Chapter 6 presents the conclusions of this thesis with respect to the improved copper recovery from a sulphide-oxide copper ore and a mixed collector flotation system. This chapter also outlines potential areas of future investigations to improve copper recovery and grade from this type of ore.
Recovery of metal values from copper slags by flotation ...
In the flotation step, a copper concentrate containing approximately 11% Cu was produced with a 77% recovery while 93% of the cobalt stayed in the tailings.
A New Collector for Effectively Increasing Recovery in ...
results indicated that the copper oxide flotation recovery increased from 79.67% to 83.38%, and the grade also raised from 18.08% to 18.14% after using the staged flotation technology with ZH-1 as collector during the flotation of 25 m ore. It was confirmed that this technology was quite e ective
Flotation Oxidised Copper Ore - arbeidsprobleem.nl
In this study, flotation of oxidised ores rich in copper and cobalt from Mupine deposit in the Democratic Republic of Congo had been investigated. This ore contains 4.85% copper, 0.16% cobalt. The recovery of copper and cobalt was performed using flotation to increase the concentration of copper and cobalt.
PROCESS OPTIMISATION OF MIXED COPPER ORES THROUGH …
The variability of the Kansanshi mixed ore in terms of total copper and acid soluble copper grades has a major impact on the flotation recovery. In March 2011, three Blue Cube MQi (in-line mineral quantifier) analysers were installed on the mixed ore flotation feed, concentrate and final tails respectively.
