This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1919 edition. Excerpt: ...of the work was to find out what effect iron sulphate has upon the electrolytic precipitation of copper from copper sulphate solutions by the use of insoluble lead anodes, and also under what General Engineer, Westinghouse Electric & Mfg. Co., East Pittsburgh, Pa. conditions of current densities and temperature of electrolyte the effect of the presence of the iron sulphate in the copper sulphate solution is the most detrimental. I cannot understand how they should have had the idea that the experiments "were done for the object of determining what deleterious effect iron would have in the electrolytes as used in electrolytic copper refining." The first two paragraphs under Experimental Part state exactly the object of undertaking the experiments. Mr. Witherell also failed to appreciate that the experiments on pages 131 and 132 which he criticises are not ones upon which the article is based, but that these experiments of Bell were made by Bell to confirm the results of. Elbs, and also those of Schwab and Baum; all of these experiments were to determine the effect of iron salts in copper coulometer electrolytes. I merely made reference to these experiments. The third paragraph under Experimental Part should have convinced the readers that alcohol was not used in the electrolytes of the 36 experiments. The solutions are in a way similar to the pregnant copper solutions obtained in the leaching of copper ores on a large scale. Mr. Witherell and Dr. Fink know that iron salts in the solutions obtained at Chuquicamata cause deleterious effects. I am sorry that Mr. Witherell did not read the article carefully, because had he done so, I feel certain that he would not have made some of the criticisms which he offered. The statement...
