Investigating the reprocessing of Carolin mine tailings

Tailings and Mine Waste Conference (2011 : Vancouver, B.C.); University of British Columbia. Norman B. Keevil Institute of Mining Engineering

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.
