An understanding of our fragile environment can begin with a recognition of the importance of certain elements, commonly called "minerals substances" (such as iron and zinc), in the lives of humans and animals and in the soils that support plants. This recognition is well deserved because these elements are essential...

1993, Book chapter, Environmental geochemistry of sulfide oxidation
Time-series data on Zn/Cu weight ratios from portal effluent compositions [(Zn/Cu)water] at Iron Mountain, California, show seasonal variations that can be related to the precipitation and dissolution of melanterite [(FeII,Zn,Cu)SO4·7H2O]. Mine water and actively forming melanterite were collected from underground mine workings and chemically analyzed. The temperature-dependent solubility of Zn-Cu-bearing...

Manganese minerals and associated fine particulates in the streambed of Pinal Creek, Arizona, U.S.A.: a mining-related acid drainage problem
Carol J. Lind, J.D. Hem
1993, Applied Geochemistry (8) 67-80
The Pinal creek drainage basin in Arizona is a good example of the principal non-coal source of mining-related acid drainage in the U.S.A., namely copper mining. Infiltration of drainage waters from mining and ore refining has created an acid groundwater plume that has reacted with calcite during passage through the...
