The furnace additionally creates 90% much less airflow, which means fewer fumes.
“The brand new furnace has nice enchancment in security for the gold room staff,” Course of Supervisor, Quenton Johnson, stated.
With cascade moulds and a bigger crucible, the furnace heats extra gold directly, reaching 1,100°C – properly above its 1,064.2°C melting level.
“So, for instance, as an alternative of getting to do say 4 separate pours to get 4 bars, we now do one pour and 4 moulds will fill with gold,” Johnson stated.
The furnace is way extra dependable and considerably reduces emissions, the EECA claims.
That is the corporate’s second huge transfer to electrical energy, following final yr’s introduction of a brand new electrical shovel — additionally a New Zealand first.
Each shifts to electrical gear have been co-funded by EECA and help OceanaGold’s purpose of reaching net-zero operational emissions by 2050.
