Abstract The U.S. Department of Interior, Bureau of Mines is conducting research on the capacity of natural fluid/rock interactions to attenuate major and trace elements at the Santa Cruz In Situ Copper Mining project site. This report presents results from a series of experiments designed to quantify the changes that natural reactions will cause in the composition of mining leachate with time. Several different rock types in the Santa Cruz area were tested and the effect of rock type on attenuation was evaluated. Calculated experimental attenuation coefficients are presented as a method of quantifying attenuation capacity. Geochemical reactions that can cause subsurface attenuation of various leachate constituents are also discussed.
