The composition of ores of the Kutyn gold deposit

Abstract

The results of mineralogical and metallurgical study of selected geometallurgical samples of partially oxidized ores with low gold cyanide leaching recovery from Kutyn deposit are presented. The samples had carbonate-sericite-feldspar-quartz composition. Correlations between contents of minerals and elements indicate presence of six main mineral-elemental associations. Three classes of ore were distinguished based on arsenic oxidation degree due to significant variations in gold recovery by both flotation and cyanidation. Potential prediction model for gold recovery by flotation according to the ore composition was proposed.
