PMAP is committed to standing beside its clients to provide safe, environmentally friendly, sustainable and green solutions for Acid Rock Drainage (ARD) and acidic tailing ponds in the mining industry. We strongly believe in responsible mining as the future of the mining industry and we want to support the industry by providing practical and feasible solutions for tailing pond issues in the mines around the globe.
PMAP services are focused on treating the low-pH waters in the tailing ponds. The PMAP team can provide full services including identifying the issue and metal recovery potential, conducting bench scale process development tests, conducting pilot plant studies and providing full on-site treatment services.
PMAP offers a wide variety of services including temporary on-site treatment for both active and inactive ponds, permanent water treatment facility design and operation, optimizing the existing treatment facility, valuable metal recovery operation and post-closure pond cleaning.
Process Development Tests
The PMAP team has vast experience with different mine waters and can conduct bench-scale lab tests to prove the treatment concept, determine the optimum use of PMAP reagent and present the quality of the treated water. In addition, the PMAP bench scale tests would unveil the valuable metals’ recovery potential as well as required steps to achieve the recovery goals.
Pilot Plant Studies
At PMAP, our substantial experience with conducting water treatment pilot plants is used to improve the selected process and to collect necessary engineering data for the scaled-up operation. Our team creates and maintains a stable, reliable treatment process by analyzing the collected data and applying engineering principles. The pilot plant service could be extended to utilize the knowledge of our team for designing a full-scale treatment facility.
Temporary On-site Operation
For various reasons, including the short lifetime of the operation as well as other financial reasons, establishing a permanent treatment facility is not a viable option. To counter this, PMAP developed mobile water treatment units to complete the treatment task as standalone units. The self-contained PMAP units could work in remote areas without electric power or other facilities. Due to the unique application of artificial intelligence in the PMAP mobile units, the systems could work with a minimum number of skilled workers. Also, thanks to eliminating the need for transferring large volumes of water, the units can work with very limited power which would easily be provided by small power generators. This service was designed based on the vast experience of the PMAP team working in a remote area. This service is particularly suitable for mines in remote areas without treatment facilities.
The PMAP method could be a suitable replacement for lime treatment by creating lots of financial and operational benefits for the mine. However, some sites have already established a lime treatment facility and it wouldn’t be desirable for those mines to abolish their existing facilities and use different technology. The PMAP engineering team could offer solutions to maximize the use of the existing lime facility to optimize the cost of operation while providing the benefits of the PMAP technology. The existing lime silo and lime mixing facility could be modified for the PMAP process and the existing mix tanks could be adjusted for optimum use in the PMAP process.
Valuable Metals Recovery Services
The PMAP process could be used as a stand-alone two-stage process or as a pretreatment in front of the lime process to precipitate less valuable metals in the pond. In this service, the PMAP process will produce two different sludges with high concentrations of one or more valuable metals in each sludge. This PMAP service was designed to maximize the concentration of only selected metals in the sludge by reducing the concentration of less valuable metals in the sludge and reducing the overall volume of the generated sludge. The PMAP process could be customized to meet the client’s needs while generating revenue from the wastewater treatment process.
