Dry Stack Tailings are becoming an increasingly viable and attractive alternative to tailing impoundments in the mining industry. A Filter Press delivers some of the best results from competing dewatering technologies. By dewatering tailings to a relatively “dry cake,” this stable and stackable form of storage is ideal for mining companies.

Metso Tailings Management brings a comprehensive approach by combining 3 practices: Dewatering the tailings, handling them with dry stacking, and reprocessing new and existing ones. We also look to elevate the approach to reduce social hazards and associated risks, which will improve the overall image of the mining industry.

A primary demand was the ability to supply a cost-effective dry stacking technology ideal for dry climate mining operations that reduced water requirements. With FLSmidth’s advanced stacking capability (machinery working off stacked pile) and ability to stack tailings at 15% moisture content, this meant tangible water savings for Karara.

Gold tailings: Xinhai usually use all-slime cyanide process and carbon-in-pulp process to recover the gold from gold tailings. As for the gold tailings cyaniding, xinhai will apply the method of dry-tailing stacking. That is, though the process of classifying and dewatering, at the same recycling the water recourses to remove the cyanide in it.

However, recent developments in dewatering equipment designs are reducing costs to the point where high capacity filtration and dry stacking of tailings is now comparable with storage in dams over the life of the project, particularly for projects in arid environments with high water costs (Pyle, 2019).
