Effective Parameter Predictions in Metals Transport from the Zanjan Zinc Mine Tailings using PHREEQC.

The effects of grain size distribution, initial flow rate, and initial pH were simulated using PHREEQC to determine how these factors affect the transport of Cd, Ni, and Mn from the tailings of the Zanjan zinc (Iran) leaching plant. Not surprisingly, lower pH, higher flows, and smaller effective particle size increased metal transport. The simulation results generally agreed well with results from a previously conducted column study. [ABSTRACT FROM AUTHOR]
