Microbial Leaching of Ores Pyrite is not the only mineral oxidized by A. such as copper are often present in ores as sulfides. A. ferrooxidans can convert the sulfide chalcolite (Cu 2 S) to covellite (CuS) to obtain energy. Copper miners take advantage of this metabolic step during the microbial leaching of lowgrade ores.

Dyeleaching test for the freshness indicators There are no standard methods yet to analyze dye leaching from freshness indicators. Therefore, to evaluate dye leaching from the asprepared freshness indicators, a leaching test was carried out according to Regulation (EU) No. 10/2011, related to the migration testing of plastics in contact with ...

Conversely, microbial leaching from pumice sand and other sandy soils requires relatively larger volumes of irrigation water. The microbial leaching potential of soils is in the descending order of structured clay soils, silt over gravels, silt soils, sandy soils, pumice sand soil and allophanic soils (Figure 1).
