"Recent improvements in the practice of milling lead ores of the Southeast Missouri Lead Mining District has resulted in the production of low-grade mill tailings. The tenor of the lead in the tailings is often between 0.05 and 0.25 per cent. In view of the fact that large tonnages are handled daily and that further improvements are under way, it is imperative that the lead content of these tailings be accurately determined.
For this purpose an electrolytic board, which speeds up the electrolytic determination of lead in low-grade mill tailings, has been devised at the Mississippi Valley Experiment Station of the United States Bureau of Mines, in cooperation with the Missouri School of Mines and Metallurgy, Rolla, Missouri.
The electrolytic board is the result of several years work in cooperation with large lead mining companies. The method employed in the determination of small amounts of lead has been included as well as certain precautionary measures"--Introduction, page 1.
