The Canadian mining sector is a cross-country presence, with mines in every province and territory contributing over $155 billion to the economy (7.8 percent of Canada’s GDP (2019)). As pressures on Canada’s mining sector grow, the sector as a whole is seeking to develop sustainable approaches to mining which in addition to contributing to the economy can protect the environment.
Treating and discharging Acid Rock Drainage (ARD) and processing water is an ongoing environmental challenge for the mining industry in North America and around the globe. Those streams, which were generally collected in tailings ponds, consist of heavy metals and other toxic contaminants that required neutralization and removal before discharging to the receiving environment. Due to the complexity of mine water issues and associated risks, selecting a proper water treatment approach became a multi-criteria decision-making process with an adverse range of stakeholders. Two major risks of treating mine wastewater are transferring the contaminated water from the pond to a secondary reserve and transporting and handling large quantities of the hazardous neutralization reagents.
The experts in PMAP use their vast knowledge and experience to tackle treatment risks by developing environmentally friendly, non-hazardous and biocompatible neutralization reagents to convert the tailing pond into a gigantic neutralization reactor. The PMAP technology eliminates the need (and associated risk ) of transferring contaminated pond water to a secondary location for treatment. Also, thanks to the non-hazardous nature of the invented formula, the PMAP technology removes all risks related to hazardous reagent handling and transportation.
The use of artificial intelligence prevents excessive consumption of the neutralization reagent and, in conjunction with the patented formula, would guarantee the final pH at the desirable range.
The patented formula could be used in either PMAP technology or could be modified for application at the existing lime treatment plants. The PMAP technology is the most advanced and futuristic green technology for mine water treatment.
