The first step in the ,acid, mine drainage flowsheet is de-carbonation. In many cases, chemical consumption is the number one operating cost of an ,acid, mine drainage ,treatment, system. As such, it is critical that chemical usage be optimized. Typically, with ,acid, mine water, there is a high amount of CO 2 in the waste stream.

Wetlands and anoxic limestone drains (ALDs) are ,passive treatment, systems in contrast to ,active, chemical ,treatment, systems. Wetlands have been used for decades in the ,treatment, of municipal ,wastewater, (WPCF 1990) but only within the last 10 years have they received serious attention in the ,treatment, of AMD.

Abstract ,Treatment of acid, mine drainage can be accomplished by either ,active, or ,passive treatment, systems. Choice between ,active and passive treatment, and appropriate selection of systems within each category is critical for ,treatment, success. In general, ,active treatment, is more commonly used at operational mines whereas ,passive treatment, is typically considered for closed and abandoned mines.

To avoid this environmental damage, measures must be taken, both preventative (or ,passive,) and ,active, through the implementation of ,treatment, methods for these acidic effluents. In regards to ,treatment, technologies, it is important to note that on numerous occasions a single procedure does not prove sufficient, resulting in the necessity for a combination of various procedures.
