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.

04 ene 2022Energía eléctrica y renovablesAs stated in a previous blog article on HSE risks, the challenges of producing metal powder by atomization, evaporation, plasma atomization or hydrometallurgy are very complex, due in part to product quality requirements. The aerospace (AS9100) and medical equipment (ISO 13485) markets require consistent quality products that meet their specifications, that they be delivered within specific time frames and are fully traceable. So, it’s important to properly control the production line to identify risks that can affect product quality and availability.Metal powder production: quality control is crucial

26 nov 2021Energía eléctrica y renovablesEvery problem in an organization can be found within an operational, support or management process. We often ask ourselves why the problem keeps occuring, and we try to solve it using the same level of thinking as when the problem originally appeared. If used properly, a simple tool named process mapping can help not only solve the problem but lead to lasting changes that reduce costs and increase profits.Common pitfalls when mapping a process

11 ago 2021Energía eléctrica y renovablesThinking of increasing your plant’s capacity, modifying your flowsheet or upgrading your equipment? It may be tempting to raze your existing plant to the ground and start with a clean slate, especially if you’ve had a hard time operating or maintaining it. But before you bring in the bulldozers, take a moment to evaluate your assets’ condition and perform a gap analysis against your expansion requirements. Deciding which equipment is worth keeping or modifying is not always obvious. In these cases, a formal trade-off study can be helpful to refine and solidify thoughts and make an impartial decision. Trade-off studies typically involve identifying several potential solutions and methodically comparing them using pre-determined selection criteria. Here are four principles to keep in mind to ensure the best outcome for your trade-off study:Reuse, refurbish or replace? How to select the right option for your plant expansion
