The ores consist chiefly of yellow copper ore, or copper pyrites, and the grey sulphuret of copper. The average produce in copper is said to be about 8 1/2 parts from 100 of the ore. The ordinary processes of smelting consist of alternate calcinations and fusions in reverbatory furnaces of the usual construction.
