"There are alternative options like dry-stack tailing, a method which absorbs all the water content in the tailing, then use the dry material for mine pit reclamation," he said. Dry-stacking reduces the environmental threat towards marine biodiversity and allows metal recovery and re-extraction, while DSTD excludes these possibilities.
