Passive treatment systems are described as having little O & M costs, require little chemical application, and few if any mechanical devices (Hedin et al., 1994). Passive treatment systems can be a good solution for small drainage sites that might otherwise have few treatment options. 1.2 Chemistry 1.2.1 Acid Generation and Metals Leaching

When appropriately designed and maintained, passive systems can provide long-term, efficient, and effective treatment for many acid mine drainage (AMD) sources. Passive AMD treatment relies on natural processes to neutralize acidity and to oxidize or reduce and precipitate metal contaminants. Passive treatment is most suitable for small to moderate AMD discharges of …

The focus of the State Route 124 Seeps Project included both reclamation and treatment components. Reclamation activities included eliminating the impounding lakes, establishing positive surface water drainage, clay-capping the mining wastes, and reestablishing vegetation. Approximately 4100 feet of limestone riprap was installed along stream ...

The reclamation baghouse dust typically comprises a mixture of carbonaceous materials and heavy metals. The method comprises collecting the baghouse dust, mixing the collected dust with limestone, and compressing the resulting mixture into blocks using a pressure of at least about 3,000 psi.

Fe and Mn, passive treatment with a properly sized constructed wetland is sufficient. When mine water is acidic, successful passive treatment requires that alkalin-ity be added to the water. The most inexpensive alkaline source in coal mining regions is limestone (Table 1). the past, however, limestone has been rarely utilized in

Limestone channels. The simplest method to passively treat acidity in AMD is to drop limestone fragments into its stream channel. Alternatively, AMD can be rerouted into a ditch lined with limestone. Either way, the limestone dissolves as water flows over it, adding alkalinity and increasing pH.

Abatement & Treatment. Design of the correct system for each mine site to be reclaimed takes additional time for surveying, drilling, sample analyses and design plan preparation. Along with landowner negotiations and leveraging funding from outside partners, considerable time can be expended before reclamation or treatment even begins.

Reclamation of abandoned mine lands can be achieved by either preventing the formation of AMD or by treating it after it has formed. AMD can be prevented by removing pyrite from the mine site or by burying it to minimize its reaction with oxygen. ... One early treatment approach was the anoxic limestone drain (ALD, fig. 2) that uses limestone ...

Acid Mine Drainage Treatment with Armored Limestone in Open Limestone Channels P. F. Ziemkiewicz, J. G. Skousen,* D. L. Brant, P. L. Sterner, and R. J.

In lime precipitation, two treatment options are available, single-stage and two-stage. The choice of system depends primarily on the alkalinity of the water. In single stage treatment, lime is mixed with feed water to raise the pH in the range of 9.5 to 11.0. This process is well-suited to hard waters with alkalinities above 25 0 mg/1 (1);

amount of treatment is used to dry and temporarily modify soils. Such treatment produces a working platform for construction or temporary roads. A greater degree of treatment--supported by testing, design, and proper construction techniques--produces permanent structural stabilization of soils.

Armoring of limestone is a common cause of failure in limestone-based acid-mine drainage (AMD) treatment systems. Limestone is the least expensive material available for acid neutralization, but is not typically recommended for highly acidic, Fe-rich waters due to armoring with Fe(III) oxyhydroxide coatings. A new AMD treatment technology that uses CO2 in a pulsed limestone bed reactor ...

A new passive treatment technology which employs a combination wetland/anoxic limestone drain (WALD) is currently being evaluated at one AML site near Thomas, WV. The WALD utilizes a three cell design to complete treatment. Cell 1 (dimensions 365.8m x 2.5m x 1.8m- L x W x D) employs a 0.6m base of limestone overlain by 1.2m of organic material.

In passive treatment systems, as a general rule, limestone is the favored product used in adding alkalinity because it is cheap, plentiful, and safe. The heavy metals each exhibit their own behavior in precipitation, both in pH and the physical characteristics of the precipitate.

Limestone is an alkaline agent with the ability to neutralize, or partially neutralize strong acids. The neutralization process occurs when strong acids, in intimate contact with limestone chips, react with Calcium Carbonate (CaCO 3, the primary constituent of limestone) to form water, carbon dioxide, and calcium salts.The following depicts the neutralization of hydrochloric acid by limestone.

Farmers can use the resulting byproduct as a agent. The acid neutralizing value of the water treatment lime can be similar to, or even greater than ground ag lime. The material is also very fine, and dissolves and reacts quickly in the soil solution. By the nature of its production, water treatment lime is very wet – 40-50% moisture.
