Abstract
"Samples of material in the spoil banks left by surface coal mining operations in Henry County Missouri were taken from various depths and preserved to prevent further oxidation of the pyrite in the samples. Quantitative determinations were then made for sulfate and sulfide sulfur. It was shown that near the surface the sulfide sulfur concentrations were much lower than those at greater depth while sulfate concentrations were higher near the surface than at depth. Since this is probably the effect of years of oxidation of the pyrite, it can be used to show at what depth the pyrite is being oxidized. The sulfide concentrations increased dramatically below a depth of two feet, so it was concluded that most of the oxidation took place in the top two feet of the spoils.
Preliminary methods were developed for using the sulfate and sulfide determination along with calcium and magnesium determinations to predict the quantity of acid that the spoil pile was capable of producing"--Abstract, page ii.
