Improvement of Mining and Processing Flowsheets at Structurally Complex Ore Deposits

Journal of Mining Science Aims and scope

Abstract

The article describes the integrated analytical studies and geotechnical assaying of blasted ore samples with size classification at a gold deposit. The parameters of mixed fractions for processing using different technologies are determined. The ore mining and processing flowsheet is developed for a structurally complex extraction block. An improved technology is proposed for the structurally complex ore deposit. Selective ore extraction is followed with screening and size classification into fractions with high and low contents of useful component. The fractions are blended, the blend with the high content of useful component is subjected to flotation, and the blend with the low content of useful component goes to heap leaching. The fraction with the increased content of useful component from rich ore is treated by two-stage sorption and leaching pre-oxidation, which ensures high metal recovery.
