Solutions to reduce moisture in the filtered tailings material and improve the efficiency of the water recovery system
What we are looking for?
In the management and handling of tailings at the Las Cruces II deposit (DLC.II), Pucobre must address the challenge of ensuring the moisture content of the filtered tailings meets the design criteria for optimal compaction (standard Proctor >95%). This is the most critical variable for ensuring the physical stability of the deposit during the construction phase.
The filtered tailings are used to build the resistant prism or containment wall. The main impact of high moisture content is that it prolongs construction cycles, delaying the process. To be more efficient, a technology is needed to reduce the moisture content (water weight/solids weight) from 16% to 12% in fewer days.
Additionally, Pucobre seeks to improve and optimize the water recovery from the tailings deposited in the DLC.II basin. The objective is to capture the largest amount of water possible before it infiltrates the deposit’s foundation soil and is then captured downstream by the hydraulic barrier.
By recovering more water, the company improves its water efficiency and increases the available volume in the DLC.II basin, resulting in an increase in its total storage capacity.
How will we evaluate your solution?
The KPIs to be impacted are:
- Reduction in the moisture content (on a solids weight basis) of the filtered tailings from 16% to 12%.
- Improved and optimized water recovery from the DLC.II basin. This will result in an increase in the deposit’s useful volume and a decrease in infiltration into the foundation soil.
