Acid Mine, Drainage Prevention 1. Surface water dispersion The purpose of this action is minimizing water in contact with the potential ,acid, material. The method is easy to apply but need to be careful in diverting the water. 2. Soil compaction The purpose of this step is to reduce the soil permeability.

We are developing a commercially viable bioleaching process to recover nickel and elemental sulfur from these tailings, while reducing the risk of ,acid mine, drainage. In this process, iron oxidizing bacteria work as catalysts in oxidizing ,ferrous, iron to ferric iron. The ferric iron creates an oxidizing environment which favours nickel leaching.

Si, Al, Fe Ca, and Mg alone form more than 85% of the chemical compounds and glasses of most fly ashes. Fly ash has a chemical composition of 70–90%, as well as glasses ,of ferrous,, alumina, silica, and CaO. Therefore, fly ash could act as a reliable and alternative source for ,ferrous,, alumina, and silica.

A typical culture medium ,contains, Fe 2+ from ,ferrous, sulphate. Bacteria like A. ferrooxidans, oxidize Fe 2+ producing Fe 3+ by eq. (1). Then, Fe 3+ attacks the pyrite, releasing more Fe 2+ ions by eq. (2) which are taken by bacteria, creating a cycle of Fe 3+ regeneration [8,9].

8/9/2018, · The acetogens use the products of primary fermentation, such as propionic ,acid,, butyric ,acid,, lactic ,acid, and other substances to produce acetic ,acid, and H 2. This work shows that acetogens have a narrow ecological niche and they are more likely than methanogens to be affected by changes in the external environment [ 33 ], particularly changes in temperature and pH value, etc.
