Production. Tin smelting. Long tubes carry all the smoke thrown off by the furnaces of a Southern tin smelter to Cottrell precipitator units. Here all tin carried in the smoke is removed by an electrical current of 65,000 volts, and added to the metal secured more directly in other stages of the process. The large amounts of pure tin recovered from South American ore in this plant serves countless war purposes of the United Nations

Production. Tin smelting. Tapping the furnace of a Southern tin smelter in which pure tin is extracted from the raw ore of South American mines. Here tin is drawn off into floats which weigh about eighteen tons when filled. The metal is then conveyed to polling kettles, where dross or skimmings are drawn off and forwarded to another furnace for re-melting

Largest open pit copper mine in the world at Santa Rita, New Mexico. Copper was discovered here by an officer of the Spanish army in 1800 who sold the same to a wealthy Spanish merchant. Pure native copper was transported by pack mule to Mexico City to enter the royal mint for coinage. In 1900 a young mining engineer became interested in the development and was instrumental in the ultimate success of the Chino Copper Company. The ore is now shipped to Hurley, a short distance to the south, where it is put through a five million dollar smelter

Science and research. Mineral prospecting. Electrical prospecting for metallic minerals may be carried on by using the dual coil radiometer to measure the electro-magnetic field of the earth, as it may be influenced by the presence of an ore body. Students training for war jobs in the minerals industry, or for service with the armed forces, are shown hunting for ore. A student at the left operates the field generator. The coils about the middles of the two others are made up of many strands of copper wire which act as transformers. The student second from right watches the level on his stationary coil to measure the electro-magnetic field. After completion of training, many students will be given commissions in naval ordnance, where they will use electronics for airplane detection. Colorado School of Mines, Golden, Colorado
