Abstract

An attempt has been made to apply an enlarging pore model to the ammoniacal leaching of chrysocolla (CuSiO3· 2H2O) using the experimentally measured values of conversion (percent extraction), pore volume, and surface area. There is good agreement between the measured and predicted surface area values up to a fractional conversion of 0.45. The measured surface area and pore volume of chrysocolla increase with extent of leaching up to a fractional conversion of 0.6 and thereafter decrease.
