Passive treatment of acid mine drainage water: a sustainable solution
Publicaciones
-
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.

05 ago 2019Energía eléctrica y renovablesAdvanced process control (APC) improves performance, stabilizes production, handles constraints, protects equipment and manages grade changes. At first glance, this solution might seem interesting to businesses. However, before adding an APC to an existing system, it would be wise to take a step back and assess the situation. For example, studies show that you can increase production by 1.5% by optimizing equipment use and basic control loops; however, advanced process control can increase production by 1.4%, for a total of around 3%. Of course, the first 1.5% is much easier to obtain and requires little investment. The simplest solutions are always the best: why make things more complicated if performance (production, quality, etc.) does not justify it? Profitability analyses should be conducted to validate project viability. Needs—not trends—should dictate choices! We have prepared a few questions that will help you start your planning, especially if you are thinking about implementing optimization solutions in the near future.Do you need advanced control?

27 jun 2019Biocombustibles, petróleo y gasMore stringent regulations have been adopted to help reduce SO2 emissions measured under various parameters. In Canada, four provinces are reducing SO2 emissions (New Brunswick, Nova Scotia, Québec and Ontario) to comply with specific regulations and the Canada-wide Acid Rain Strategy. The 2019 review of Regulation 419/05 in Ontario is a clear example of the new limit reduced to more than 2.5 times compared to previous levels. Strict standards are also in effect in Québec (chapter Q-2, r. 4.1 of the Clean Air Regulation) and have been updated continuously since 2016. Canada has also adopted Ambient Air Quality Standards. In the United States, the Clean Air Act has required sustained monitoring measures and mitigation plans for over 10 years.Proven methods for reducing sulfur dioxide (SO2) emissions
