| Abstract: | The physical and chemical characteristics of a chrysocolla-bearing copper ore have been investigated with special emphasis on elucidation of its pore structure through gas adsorption techniques. The effect of such variables as particle size and outgassing temperature on the pore structure and size distribution has been investigated in detail. The results obtained show that the chrysocolla is a microporous solid and that its microporous nature can be considerably altered by heat treatment around 550°C. A possible reason for the so-called “thermal activation of chrysocolla” has been postulated. |
