flotation processing for cu

flotation processing plant. The project began in early 2007 and was commissioned in November 2008. The plant was initially designed to process high Cu-low Zn ores (with Cu to Zn ratio 5:1) to produce marketable copper concentrate only. The concentrates produced at the Canatuan mine are shipped to a

Process of Grinding fineness test is shown in Fig. 1, and the test results are shown in Fig. 2. Rougher Flotation Z-200:100 2 S+NaHS+ZnSO 4:1100+1500+1100 Dosage unit:g/t Mill Copper Rough Conc.

The increasing complexity of ore deposits, declining ore grades and higher global demand for copper has resulted in increased ore processing by flotation plants around the world

Table 1: Grade/recovery performance of a hypothetical copper ore flotation process. Product % Weight % Cu Assay Feed 100 2.09 Concentrate 10 20.0 Tailings 90 0.1 (a) From Table 1, the Ratio of Concentration can be calculated as F/C = 100/10 = 10. If only

Apr 17, 2019 Embedded in a cloth of complicated Cu-Pb-Zn sulphide ore froth flotation process, the use of the potential regulation flotation technology of whole process priority, with lime slurry potential and adjustment to the LP - 01, SN - 9 + aniline aerofloat and butyl xanthate were collecting copper, lead, zinc, and use a combination of zinc sulfate

Current Situation on Flotation of Cu-Pb-Zn Sulfide Ore Jian-Tao Lang1, Si-Qing Liu2,*, Xu Dong3,Yi Pei4 1,2,3,4 Kunming University of Science and Technology, Kunming City, Yunnan Province, China *[email protected].com Keywords: Copper-lead-zinc sulfide ore, Flotation process, Separation of bulk concentrate, Flotation column Abstract. In the flotation of copper - lead - zinc polymetallic sulfide

Flotation Process For Copper. Home Flotation Process For Copper. PEW series Jaw crusher features big crushing ratio, reliable operation, easy maintenance and low operating cost. ... Vibrating Feeder is a kind of linear-direction feeding equipment, in the mineral ore &rocks processing plants, it can send

Nov 01, 2019 The processing routes and reagents used vary in these processes. Typical flotation flowsheets involve either sequential flotation of Cu (first) and Ni (second) from the ore (e.g., Strathcona and Kevitsa mines), or bulk flotation of the sulphides and subsequent Cu-Ni separation (e.g., Thompson, Clarabelle, Jinchuan and Norilsk)

The flotation process depends on several design and operation variables. We consider a superstructure that includes three flotation stages: rougher, scavenger and cleaner stages as it is shown in figure 1. We allow for the consideration of multiple scenarios. ... 17.7% Cu and 0.69%As, and a completely flexible structure for each scenario

Jul 20, 2021 The flotation process has the advantages of both preferential flotation and mixed flotation, and it is easy to control the process conditions of flotation separation. Application: The flotation process is mainly suitable for the copper-lead-zinc sulfide ores with similar floatability. 04 Iso-flotation process

Moreover, the grades of Cu and Co were 13.4% and 4.81%, respectively, with 85.07% of the ore weight discarded as tailing. The consideration of sulfide aggregates instead of singeral minerals mineralogy characters in primary grinding and primary flotation provides an effective theoretical guide for the sorting of sulfide minerals and reduction

Apr 13, 2016 Copper Sulfide Flotation Circuit. The pulp from the Conditioner is treated in a 10-cell “Sub-A” Flotation Machine and a 4-cell “Sub-A” Flotation machine. Sometimes conditioners are not provided; however, their use insures that reagents are thoroughly mixed into the pulp ahead of flotation

Jul 25, 2013 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 content. Mineralogical characterization of the ore is a prerequisite to any flotation testing

Jun 15, 2018 Jun 15, 2018 A new flotation tailings treatment process was developed for efficient Cu recovery. • An efficient Cu dissolution was achieved in an H 2 O media in presence of pyrite. • The dissolution mechanism of CuFeS 2 has been confirmed to be a multistage reaction. • Fe was always co-dissolved with Cu following a linear relation of C Fe = 38.393 C Cu. •

Apr 17, 2019 The froth flotation technology of copper, lead and zinc sulfide ore is very rich. A certain copper, lead, zinc and sulfur ore in Tibet is used for partial mixed flotation process. It is mixed with medium ore for regrinding, and activated carbon is used as the agent for separation
