May 16 2016 After the rougher flotation concentrate is reground it is cleaned twice in additional Free-Flow Flotation Machines with the recleaned concentrate going to final concentrate filtration or as the metallurgy dictates to a copper-moly separation circuit. The tailings or middlings from the flotation cleaning circuit can either go to a cleaner scavenger circuit as shown on the flowsheet or can be returned to the original rougher flotation

In this manner through a series of steps the copper ore is concentrated to an eventual value of over 28 copper. Waste rock particles do not adhere to the bubbles and drop to the bottom of the tank. The waste material that comes out of the bottom of the tanks at the tail end of this process is called tailings.

slag flotation tailings are inferior in terms of leaching when compared to the slag because most of the liberated copper phases have been removed by flotation. Based on the chemical compositions of the slag and the slag flotation tailings Table 1 it can be concluded that the copper dissolved from the slag flotation tailings mainly

Leaching Characteristics Of Upgraded Copper Flotation

Leaching Characteristics Of Upgraded Copper Flotation

AbstractThe copper flotation tailings from Konkola Copper mine in Nchanga Zambia were used in the study. The purpose of this study was to determine the leaching characteristics of the tailings material prior and after the physical beneficiation process is employed. The Knelson gravity concentrator KC-MD3 was used for the beneficiation process.

Dynamic Froth Stability Of Copper Flotation Tailings

In this work dynamic froth stability is used for the rst time to investigate the otation behaviour of copper tailings. Reprocessing of material from tailings dams is not only environmentally desirable but also increasingly economically feasible as head grades can be high compared to new deposits. Flotation tailings however usually

Recovery Of Copper From Flotation Tailings By Leaching

Recovery Of Copper From Flotation Tailings By Leaching

Abstract A technology route of Reverse flotation of acid-consuming gangue mineralsAcid leaching for copperExtractingElectrodepositing is proposed for recovery copper from a tailings with high content of calcium oxide and magnesium oxide and high content of combined copper oxide. The effect of H 2 SO 4 concentration leaching time and stirring speed on copper leaching was investigated.

Common Copper Tailings Reprocessing Methods Xinhai

Nov 16 2020 If copper tailings are directly recovered by sulfide flotation it will not only affect the yield but also waste a lot of chemicals. Therefore before using the sulfide flotation method to treat copper tailings it is necessary to pre-enrich the original tailings to discard a large number of gangue minerals in advance reduce the subsequent processing volume avoid waste of chemicals and increase the

Development Of A Combined Flotation And High Pressure

Development Of A Combined Flotation And High Pressure

For recovery of copper and nickel from mine tailing a number of flotation tests were carried out at fixed PAX dosage of 50 gt fixed MIBC dosage of 200 gt pH of 6 for 6 minutes when the pulp density was varied from 10 to 25. Experimental results were summarized in Figure 6.

Leaching Kinetics Of Copper Flotation Tailings In Aqueous

Leaching Kinetics Of Copper Flotation Tailings In Aqueous

Apr 01 2013 The main copper minerals contained in the flotation tailings are chrysocolla malachite and cuprite with the copper grade of 1.12. Effects of lixiviant concentration solidtoliquid ratio stirring speed and reaction temperature on copper leaching ratios at various time were investigated.

Leaching Of Trace Amounts Of Metals From Flotation

Leaching Of Trace Amounts Of Metals From Flotation

Oct 25 2018 Initial material represents the tailings of flotation circuit. The studied sample contains several metals of interest 3.56 iron 0.04 cobalt 0.04 zinc 0.03 nickel and 0.09 copper the main elements being SiO 2 54.4 MgO 9.47 and Al 2 O 3 2.87.

Kinetics Studies On Effect Of Recycled Water On Flotation

Kinetics Studies On Effect Of Recycled Water On Flotation

Batch rougher flotation study was conducted on copper tailings from Benambra to compare flotation kinetics at optimised condition using Melbourne mine dewnised and recycled waters. The results showed an enhanced copper grade and recovery when deionised water was used as compared to when Melbourne mine or recycled waters were used the greaterflotation rate was due to the near absence
