Method of improving metal recovery by using a sulphide enrichment plant without incurring smelting fines, and a method of using a metal sulphide enrichment plant, which enriches a flotation circuit and a thickener

摘要

A method of operating a concentrator may comprise producing a final copper concentrate and periodically or continuously analyzing the produced final copper concentrate to obtain a grade value of the produced final copper concentrate. The produced final copper concentrate may be sent to a downstream smelting operation if/when the grade value of the produced final copper concentrate is at or above a minimum acceptable grade threshold and may be sent to a downstream hydrometallurgical operation capable of producing copper cathode, if/when the grade value of the produced final copper concentrate is below or falls below the minimum acceptable grade threshold.
