Investigating the reprocessing of Carolin mine tailings

Tailings and Mine Waste Conference

Investigating the reprocessing of Carolin mine tailings Daniel, Adrian; Downing, Bruce W.

Abstract

During the ten year period between Aug 2001 and Aug 2011 the price of gold has experienced an increase of nearly 1500 USD, a jump from 300 USD/oz to close to 1800 USD/oz. This has resulted in a resurgence of interest in gold tailings for what was once below cutoff grade material which is now valuable ore. The tailings at Carolin Mine are the post-processed product from the previous operation which ran from 1982 to 1984 when the average overall gold recovery was 50.2%. This low recovery indicates that a substantial amount of gold-bearing material was sent to the tailings impoundment. This paper describes the history and methodology used in re-evaluating the Carolin mine tailings material as part of a metallurgical feasibility program. [All papers were considered for technical and language appropriateness by the organizing committee.]
