Microbial Leaching

Microbial Leaching

Microbial leaching, also known as bioleaching, is an environmentally favorable method for extracting metals from low-grade ores using specific microorganisms. This biotechnological approach is particularly valuable for mining operations targeting copper, gold, and uranium, where traditional extraction methods may be economically or environmentally impractical.Copper Leaching and Microbial CatalysisIn copper bioleaching, crushed ore is arranged into heaps and irrigated with a dilute sulfuric...

Acid Mine Drainage

Acid Mine Drainage

Mining activities that disturb sulfide-rich rocks, particularly those containing pyrite (FeS₂), initiate a cascade of geochemical and microbiological processes with serious environmental implications. When exposed to air and water, pyrite undergoes oxidation, releasing sulfate, ultimately forming sulfuric acid and mobilizing heavy metals into surrounding water systems. This phenomenon, known as acid mine drainage (AMD), results in low pH waters laden with toxic elements that threaten aquatic...

|May 8, 1981

Summary

Calcite dissolution rates in the Panama Basin increase sharply below 2800 meters, coinciding with the sedimentary lysocline. This suggests a kinetic origin for the lysocline, not solely related to carbonate saturation levels.

Area of Science:

Marine Geology
Geochemistry
Oceanography

Background:

Calcite dissolution is a key process in marine carbon cycling.
The sedimentary lysocline marks a rapid decrease in calcium carbonate content in sediments.
Understanding dissolution dynamics is crucial for interpreting paleoceanographic records.

Purpose of the Study:

To investigate the in situ dissolution rates of calcite in the Panama Basin.
To determine the relationship between water column dissolution and the sedimentary lysocline.
To explore potential causes for the observed dissolution patterns.

Main Methods:

In situ study of calcite dissolution.
Analysis of water column and sediment properties at varying depths.

Measurement of calcium carbonate content in sediments.

Main Results:

Dissolution rates in the water column increase significantly below approximately 2800 meters.
This depth coincides with the onset of the sedimentary lysocline.
Increased dissolution appears independent of the transition from carbonate supersaturation to undersaturation.

Conclusions:

The study indicates a potential kinetic control on the lysocline in the Panama Basin.
The observed dissolution patterns suggest factors beyond simple saturation state influence calcite's fate.
Further research into kinetic processes is warranted to fully understand lysocline formation.
