“…With respect to the AM, by increasing the time and power of the microwave radiation, floatability of chalcopyrite and pyrite reduced. With this regard, Can and Bayraktar, 2007 observed that the floatability of pyrite and chalcopyrite were reduced with increasing the power and radiation time which is in absolute agreement with our findings. , also showed the same phenomenon for sulfide minerals which oxidized when exposed to rich oxygen, and phase changes occurred at their surfaces.…”

“…In the case of milled ore sample, some pores are also created on the surface of chalcopyrite through microwave pretreatment (Nuri et al, 2014;Mehdilo and Irannajad, 2016). Indeed, heat adsorption might cause phase transformation and formation of different oxidation layers which starts from the surface of the mineral and continues to the core of each particle (Can and Bayraktar, 2007). In addition to the SEM images, the chemical compositions of the chalcopyrite and pyrite surfaces are displayed by EDX spectra for untreated and microwave-treated samples.…”

“…Oxidation of sulphide minerals in the presence of oxygen and water is a natural process, which affects the mechanism of collector adsorption on the surface of sulphide minerals and disrupts it (Quast, 2012;Joseph-Soly et al, 2015;Quast, 2016). Microwave irradiation on the surface of sulphide minerals increases their surface oxidation rate (Henda et al, 2005;Can and Bayraktar, 2007). For example, irradiation of these waves on the surface of copper sulphide minerals, including chalcopyrite, reduces the recovery of chalcopyrite, and as radiation power increases, the amount of this decrease is greater.…”
