Thefurnace produces a matte carrying from 35 to 55 per centcopper, which is taken directly to the converters in a ladlehandled by an electric crane having a capacity of 20 converters are 68 by 98 inches in size, and have a capacityof 5 tons. The product of the converters is blister copper,about 98 per cent fine, which is cast into large rectangularslabs for shipment to the new refiner}- built by Captain De LaMar on Kill von Kull, near New York City.
