One accepted method is to produce two products by flotation; one high copper/low arsenic, which can be treated safely by smelting and a second product, high arsenic/low copper, which can be treated safely by special pyro or hydrometallurgical routes. These latter processes will also deliver the arsenic in a manageable product [5,6].
The flotation flowsheet involves the bulk flotation of copper and molybdenum minerals followed by depression of copper minerals and the flotation, with multi stage cleaning, of plant is current treating ore at a rate of...
Flotation of cobalt bearing minerals from a mixed coppercobalt ... Results 8 38 ... The mixed copper and cobalt oxidised ores from this region present significant chal ... grade changes can result in reduced flotation plant efficiency and hence ... Equipping low grade mining areas with .
Cobalt is recovered by flotation into a concentrate wherefrom it is leached by pressure oxidation followed by solution purification (involving copper solvent extraction and iron removal), ion exchange, precipitation and electrowinning.
Fig. 1. Copper flotation circuit with sampling and measuring points The objective of the present study was to investigate the operational conditions at both bulk sulphide and copper selective circuits and to diagnose their metallurgical performances in line with the measured physicochemical parameters.
The arsenic content of Rosebery copper flotation feed is mainly present as arsenopyrite (FeAsS), containing approximately % arsenic with the remainder of the arsenic in copper sulphosalts (tennantite (CuAsS)), in a solid solution series with tetrahedrite (CuSbS). Tennantite contains approximately % arsenic.
Investigation of Flotation Parameters for Copper Recovery from . Feb 22, 2012 The copper ore bearing enargite mineral contained mass% As and Keywords: enargite, chalcopyrite, arsenic, flotation, copper .
Meanwhile, the leaching efficiencies of antimony, cadmium, indium and lead were less than %, basically achieving the selective separation of arsenic from lead smelter flue dust. More than % of arsenic was converted into calcium arsenate product and thus separated from the leach solution by a causticization process with CaO after other metal impurities were removed from the solution with the .
Arsenic contamination has become a more and more serious issue and tackling it is an important task for ensuring healthy living in the world. The development of new technologies able to remove arsenic from contaminated water represents a challenge for the researchers and can open up new possibilities for the uncontaminated water recovery.
Copper ions (if they are present in flotation pulp) activate the flotation of arsenopyrite, lowering the amount of xanthate needed for flotation [3, 5, 8]. The aim of the experimental testing, the results of which are presented in this paper, was to obtain rough lead concen trate with the low content of arsenic.

Effect of ion exchange in copper flotation in the presence of bentonite when using saline water Siyu Song, Guohua Gu and Yanhong Wang (Central South University, China) Effect of seawater on bubble interactions with chalcopyrite and molybdenite surfaces
Chalcopyrite is often associated with pyrite and economical extraction of copper demands selective depression of pyrite from chalcopyrite. Conventionally sodium cyanide is used as a depressant in alkaline conditions for the selective depression of pyrite from chalcopyrite during the froth flotation process, leading to potentially
