Passive treatment of acid mine drainage water: a sustainable solution

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.

What everyone should know about hydraulic balancing

Hydraulic balancing is a process that regulates the distribution of fluids, like water or any other liquid, throughout a system. This balancing helps ensure fluid is supplied to various system clients in accordance with design values. Balancing valves are used to equally distribute the system’s total flow.

NFPA 652-2016: owner responsibility for industrial installations in Canada

The first edition of the NFPA 652 Standard on the Fundamentals of Combustible Dust was published in September 2015, the outcome of a five-year process initiated by existing National Fire Protection Association (NFPA) committees to rework NFPA standards on combustible dust. This standard sets out a series of measures on proper management of the fire, deflagration and explosion hazards associated with combustible dust and refers users to the relevant NFPA standards. NFPA 652-2016 ushers in a new era of risk management for combustible dust.

Underground stope drill and blast designs optimization program

The easiest way to mine valuable orebodies is through the use of explosives and well-planned blasting layouts that produce fragmentation profiles designed specifically for conveyance equipment in underground mines. The design of blasting patterns is specific to not only the explosives being used but also the rock or ore type being fragmented. Many blasting designs are based solely on the experience of those developed for similar orebodies in terms of properties and orientation or individuals that have some blasting experience.
