Mineral composition of sulphide-oxide Pb-Zn ore from Rudnik mine
Explorations of the ore bodies Prlovi 1, Prlovi 2 and Z of the mined ore deposit Prlovi have included ore microscopy of mineral samples from many boreholes. The orebody Prlovi 2 is prospective for the lead (4%) and zinc (3%) concentrations of which 1.89% Pb and 1.58% Zn occur in sulphides and 2.17% and 1.44% in oxides. The purpose of the ore microscopy was to recommend, based on mineral composition and texture, how to enrich the complex sulphideoxide mineral. The paper describes the composition of the intergrown minerals and suggests the method of the mineral product recovery. Illustrations in the paper are good representative microphotographs of the identified and characteristic structural features.
