Abstract |
The heavy metal content and other geochemical data of the mine and mill waters of two mining operations in the 'New Lead Belt' of southeastern Missouri were determined and the efficiency of retention ponds in reducing high metal concentrations was investigated. The mine waters from two mines of this mining district, which is the largest lead producer in the world, showed a heavy metal content of less than 6 ppb copper, 66 ppb lead and 37 ppb zinc. The heavy metal content from the mill effluents was reduced to values similar to mine water, when the pond sizes were large enough. The concentrations of calcium, magnesium sodium and potassium, and pH allow the tracing of mine water in the streams. The retention ponds are not entirely efficient in preventing transport of metal rich rockflower into the streams. |
