CONTRACT YEAR: 2019-2020
LOCATION: Izmir / TURKEY
PROJECT DESCRIPTION: Efemcukuru Gold Mine was designed for a 11 years mine life when commissioned at 2012 after the construction and installation was accomplished. In the recent years 10 years of mine life from time being is estimated through the exploration of the new ore. However decrease and/or impurities in tenor is observed in the ore which is fed to the concentrator
Because of base metal amount, sulphur variability and tenor lowness grinding and flotation studies was executed by HMT. As a result of this studies it was decided to add column flotation at the end of a cleaning circuit. PROMER carried out the detailed engineering services for this column flotation unit which was located in the concenrator unit.
