The ores are picked, crushed, powdered, subjected to several washings and then become ready for preliminary smelting. The washed ore consists of copper pyrites, mundic and gangue principally quartz and hornblened. The furnace is formed of refractory clay and is in the form of a truncated pyramid. It is generally 18 inches deep and there are arrangements at the bottom for a blast of air with two bellows consisting of inflated goat skin.
