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.
