The increased recovery project at the phu kham copper goldess selective flotation processes were similar at approximately0 per cent for copper and gold the advantage of the less selective flotation process was that it was notailings retreatment process and project value could not be eroded with improvements in existing plant performance.
Coppergold ores. coppergold ores are significant contributors to the overall world gold production. flotation is the principal process for preconcentration of the coppergold minerals for subsequent smelting treatment. gold recovery, although important, is not always considered when optimizing the copper circuit.

Water scarcity necessitates the recycling of process water within mineral processing practices. this may however come with its disadvantages for unit operations such as froth flotation as this process is water intensive and sensitive to water chemistry. it is therefore important to monitor the water chemistry of the recycle stream of process water and any other.

In the flotation studies, the effect of aerophine 3418a collector dosage on flotation was investigated. asesult,ead concentrate of 55.13 pb was obtained and it was found that this concentrate contained 2489 ppm of ag. the amount of aerophine 3418a collector was determined as 10 gt.
This processing is described in detail in the december 2012 technicalreport, from where this information is referenced.1.8.2 stage 2it was determined thatrimary grind to0 150 m, withleaner regrind to0 28 m, in the openpit process facility will achieve an estimated 89.3 percent overall copper flotation recovery for.
Of gold enrichment technology. in this work the process of laiva mine is explained and focuses on the flash flotation and gravity separation process. achieving the goals required laboratory tests. different flotation chemicals were tested inaboratory scale batch flotation test to find an alternative flotation chemical for aerophine 3418a.

Known that aerophine 3418 is pbased sulphurous collector. it was originally developed for flotation of copper minerals and active zinc minerals. asesult, it is stated that flotation of galena and other precious metals especially silver is also highly effective 16. in addition, 3418a collector was used.
Its wide range of applications in sulphide mineral flotation has made it successful, specifically in the processing of complex sulphide ores which contain copper, lead, zinc, and silver or any combination of these elements for selective separation.aerophine 3418a promoter isnique, phosphinebased collector originally developed for the.
Chemical analysis confirm that it isomplex lowgrade copper ore with average copper content of 0,273. the content of precious metals au and ag was 0.2 gt and 1.2 gt, respectively. the main aim of flotation studies have been the effect of collector type on the recovery and concentrate grade in the copper flotation process.
Flotation of copper, lead and zinc from the bulk concentrate. this method is rarely arsenic bearing minerals at an early stage of the process such as flotation ma and bruckard, 2009. well with aerophine and mercaptan type of collectors at a.
A detailed study was conducted to evaluate the effect of particle size, ph, flotation time, collector type and addition on efficiency of tennantite flotation. it was shown that maximum copper recovery of 95,3 was obtained at ph 12.3 by lime.it was suggested to grind up to 65.72 of 0.074 mm to achieve the optimum recovery of copper and high.

Therefore, many efforts have been devoted to investigate the galvanic interactions between sulfide minerals in flotation system, including both the grinding process azizi et al., 2013, huang and grano, 2005 and the flotation process eslami andargoli et al., 2012, mu et.
To account for the latter ores polymetallic nature, the collectors aerophine and sodium isopropyl xanthate sipx were used sequentially. the objective of the study was therefore to investigate the effect of water quality on collector adsorption in the flotation of sulphide ores.
Aerophine 3418a, pax, and mibc were provided by cmg. as should indeed be the focus of future studies and for the sustainability of the flotation process. thus, the subsequent sections.
