Bachelors Theses and Reports, 1928 - 1970
The East Helena plant of the American Smelting and Refining Company is a custom lead smelter. The chief product of the smelter is lead bullion, although by-products such as matte, speiss, cadmium-rich fumes, and zinc-rich slag are also produced. While the smelter is old, many of the methods used are new, some of which have been developed at the plant.
