Asset Report
Annaka zinc smelter
Report summary
The Annaka zinc smelter in Japan uses roast-leach-electrowin technology, with the leach residue being treated by a Waelz kiln. The current capacity is 139kt/a slab zinc and there are currently no plans to increase this. The smelter is "Roaster limited" and cannot produce enough calcine. A separate roasting facility is therefore located at Onahama with calcine being sent by train to supply Annaka.
