Four mineralogical-processing modifications of the Gaisk deposit pyrite are distinguished; they differ in forms of appearance and content of gold, arsenic, silver, and zinc. The processing expediency is substantiated for separation of the gold-richest (more than 9 g/t) pyrite modification from the bulk by a gravitation-flotation scheme after preliminary grinding up to −0.074 mm in size, using the arsenic-selective reagent. In this case, it is theoretically possible that pyrite-associated gold extraction reaches 85 %. [ABSTRACT FROM AUTHOR] |
