In this work, a high pressure sintering method to prepare a pure, compact, and malleable chalcopyrite block at 0.6 GPa/270 degrees C in a cubic multi anvil press was introduced. The phase composition and elemental distribution of the pure sintered chalcopyrite block were investigated in comparison to a natural chalcopyrite ore and an impure sintered chalcopyrite block by X-ray diffraction (XRD), reflected light photographs and electron probe microanalysis techniques (EPMA). The results showed that the sample was with pure and stable chalcopyrite phase. The density and ductility of the pure sintered chalcopyrite were measured by density analyzer and grinding machine, respectively, indicating it was highly compact and easily machined.
