Production. Tin smelting. Removing slag after tapping a furnace in a Southern tin smelter. The tin extracted from the ore has already been drawn off into floats for further refining. The slag is then run off to the right into ladles which will carry it to recooking operations. The slag is reintroduced to the process for further recovery of the metal

Steel alloy manufacture. Allegheny Ludlum Steel Corporation, Brackenridge, Pennsylvania. Refined alloy steel in the electric furnace, ready for casting into ingots. The slag layer on top of the molten steel prevents the hot steel from oxidizing, thereby preserving its high quality. Steel will be drawn off through the spout at the left into ladles in the pit. This is an operation that has rarely been photographed

Steel. Ford plant. A blast furnace being cast. Here the iron ore starts on its way to becoming an automobile part. The metal travels down sanded trenches; the trench to the left is conveying molten metal to giant ladles; trench on the right carries the slag off. Blast furnaces are cast in this manner about every six hours. Ford River Rouge plant, May 1941
