The Complex is primarily fed by the concentrates from Ridder Concentrator.
The plant produces high grade zinc metal, Zn-Al alloys and small amounts of sulfuric acid.
An atmospheric leaching plant is available to process any material including complex ore.
The new technology was engineered and implemented jointly with the German experts.
Another benefit of the process is zero wastes and recycling water supply to minimize fresh water consumption.
