Porphyry copper (Cu) systems occur along magmatic belts derived in subduction zones. Our current understanding of their formation is restricted to observations from the overriding plate, resulting in a knowledge gap in terms of processes occurring in convergence zones through time.
Abstract: In order to provide an uniform feed to the processing plant, the mined from a porphyry copper deposit ore is blended in the following proportions: Propylites 31-35%; Argilizites 30-33%; Secondary quartzites 30-36 % (roughly 1:1:1). Those three types of ore differ in particle size, as well as in mineral composition.
