What happens after
closure?
Closure of the Smelter and Refinery is not as simple as turning off a switch and walking away. Numerous steps to a safe decommissioning are required, starting with things as basic as cleaning up materials.
Equipment must be dismantled and sold, repurposed or recycled. Materials, such as that stuck to the masonry in the Smelter furnace
or convertors, must be removed and shipped for processing. Electrolyte in the Refinery plating tanks must be emptied and processed. By late this year, both buildings will be brought to a safe and secure state.
The stack will be capped in September. This requires the installation of steel lattice, plywood, special paint and weather membrane. The design of the structure requires a gap between the top of the stack and the cap to allow for ventilation and ‘breathing’ of the stack.
The gap will be encased in a steel mesh to keep birds from becoming trapped inside.
The timeline for this work began with the last pouring of anodes in the Smelter in early July and pulling of the last cathode
in the Refinery in mid-July to completion of the capping at the end of September.
By the end of July almost
2.5 million tonnes of electro- nickel will have been produced in these two facilities.
Where has all this nickel gone? Examples are in the photographs on the facing page.
 The top of the Smelter stack is being capped as part of the decommissioning process.
