With silver chloride, even a great excess of lime does not impede reduction, nor prevent amalgamation, though the latter is somewhat impeded. By longer roasting of the ore, the formation of silver chloride was improved, but the ore required an addition of sulphur, in some form, to give the best attainable result. Continue to:
