Passive treatment of acid mine drainage water: a sustainable solution
Publications
-
Acid mine drainage (AMD) is a persistent environmental challenge. It occurs when sulfide minerals, exposed to air and water during mining, break down and produce acidic, metal-laden water. This contaminated water harms ecosystems, pollutes water sources and in general creates challenges for mining operations. Traditional treatment methods (active treatment technologies) can address AMD but are often costly and energy-intensive. On the other hand, passive treatment systems rely on natural biological, chemical and physical processes to treat AMD. These systems provide a more environmentally sustainable and efficient solution under the right conditions. This article explores passive treatment systems, including their types and longevity, highlighting their potential as a long-term environmental remediation approach.

25 Mar 2024Mining and MetalsNitrogen compounds can be generated during mining operations and must be properly managed because of their potential harmful effects on aquatic life and human health. For example, nitrogen compounds can be released into the atmosphere when explosives are detonated or accumulated in ground water when explosive residues leach out. This liquid fraction is usually more problematic and requires special attention.

12 Dec 2023Power and RenewablesIn the pursuit of creating secure, adaptable and resilient workplaces, health and safety (H&S) practices are undergoing a transformation. Recognizing the need for more dynamic strategies, organizations are working to shape a proactive and employee-focused H&S culture. Over the last decade, we’ve seen a catalyst for change emerge: H&S plans now serve as instrumental tools, enabling companies to skillfully protect their most valuable asset—people. This blog article explores innovative practices that are reshaping H&S for a secure work environment, which aligns with the ESG framework and emphasizes corporate responsibility. Beyond ensuring safety, this new approach also prioritizes employee development and well-being in organizational strategies.Empowering health and safety: leveraging resilience and innovation in workplace

23 Jun 2023BBA is on the verge of achieving its goal of having 30% women employees by 2030, a target modelled after Ingénieurs Canada's 30 in 30 initiative. Our firm is fortunate to be benefitting from this growing gender mix, which is a powerful driving force for creativity and innovation. There's still a long way to go to achieve parity, but we're ready to do whatever it takes to make more women feel they truly belong in engineering.Ingenious women – Tatiana Guerrero

I thought it was fascinating that we could get diamonds out of the earth, and I wanted to learn more. That’s how I found out about engineering.Ingenious women – Lyne Ricard
