Book Description

Excerpt from Lead Poisoning in the Smelting and Refining of Lead The last 15 or 20 years have seen great changes in the lead smelt ing industry of the United States. As transportation has improved, small and poorly equipped smelters 1 which had been built near the deposits of ore have been abandoned and the tendency has been to concentrate the work of smelting and refining in a few large plants, for it has proved cheaper to ship the ore to large centers where labor is abundant, than to do the smelting in the mining districts.
