· Electromagnetic Separation of Galena. Chalcopyrite, sp. gr. to, is too feebly magnetic to be separated raw, and must be roasted to either the magnetic sulphide or the magnetic oxide, these changes taking place in a manner similar to the behavior of pyrite. A oneminute roast at a red heat is sufficient to impart magnetism to ...

· The chalcopyrite sample was obtained from Guangxi, China. The pure chalcopyrite sample was handpicked and further crushed and drysieved to 2 mm through a jaw crusher and a laboratory roll crusher in turn. The 2mmsize fractions were stored for subsequent grinding, flotation, Zeta potential measurements, XPS measurements, and FTIR study.

In the present work, ternary chalcopyrite CuFeS 2 nanoparticles were blended using an effective hydrothermal method. The process saw the formation of a mixture of spherical CuFeS 2 nanoparticles and nano rods. The XRD diffractograms confirm the formation of CuFeS 2 nanoparticles and the optical direct band gap was estimated

the chalcopyrite sample after heating at 1000 K. Note that, apart from already mentioned magnetic impurities present already in the pristine chalcopyrite material, the magnetic response could be more complied due to multiphase nature of the CuFeS 2 after heating. Let us remind that chalcopyrite CuFeS 2 can exist in three phases: (i) CuFeS
