Acid Mine Drainage, Rock Drainage, and Acid Sulfate Soils. by James A. Jacobs

By James A. Jacobs

Provides the instruments had to learn and clear up acid drainage problems

Featuring contributions from best specialists in technology and engineering, this publication explores the advanced biogeochemistry of acid mine drainage, rock drainage, and acid sulfate soils. It describes how you can expect, hinder, and remediate the environmental effect of acid drainage and the oxidation of sulfides, delivering the most recent sampling and analytical tools. in addition, readers will realize new ways for convalescing necessary assets from acid mine drainage, together with bioleaching.

Acid Mine Drainage, Rock Drainage, and Acid Sulfate Soils studies the most up-tp-date findings within the box, supplying new insights into the underlying factors in addition to new instruments to lessen the damage of acid drainage:

  • Part I: Causes of Acid Mine Drainage, Rock Drainage and Sulfate Soils makes a speciality of the biogeochemistry of acid drainage in several environments.
  • Part II: Assessment of...

    Sample text

    This treatment technique is particularly useful to treat acid mine drainage in remote areas where power is unavailable. 6 Example of a caustic soda (20% liquid) tank to treat acid mine drainage. The liquid is dispensed through the hose to poor-quality drainage for treatment. 7 Anhydrous ammonia is pressurized in a tank to form a liquid. Once released, it becomes a gas and reacts quickly with acid drainage for treatment. The tank must have pressure gauges and heating elements. 8 Flocculant being dispensed in acid mine drainage to help creat larger particles that will settle faster in a pond.

    Once released, it becomes a gas and reacts quickly with acid drainage for treatment. The tank must have pressure gauges and heating elements. 8 Flocculant being dispensed in acid mine drainage to help creat larger particles that will settle faster in a pond. Flocculants and coagulants are used where insufficient residence time is available for efficient settling. 9 A simple jar test can be used to determine the amount of floc that will be generated after treating a certain volume of water with specific chemicals.
