A plant treats an ore containing Pyrite (FeS2), Arsenopyrite (FeAsS) and chalcopyrite (CuFeS2). After ore upgrading and analysis, the Arsenic (As), Copper (Cu) and Iron (Fe) concentration in the concentrate were 9.6%, 13.5% and 63.3% respectively. What is the concentration of pyrite, arsenopyrite, chalcopyrite in the concentrate?
Before the iron ore, in the form of green pellet is entering the straight grate induration furnace, it has been processed in different stages. In the sorting-plant, the crude ore that has been extracted from the mine is separated from gangue and crushed down to smaller fractions. Further on the crushed iron ore is entering the concentrating plant.
