The principle application of electricity to metallurgical operations in this part of the country is copper refining, which is carried on extensively at Anaconda and Great Falls, Montana. The plant at Anaconda consists of eight electrolytic generators, aggregating 1,870 Kw., and its capacity is 125 tons of refined copper per day, the average output being 100 tons per day. They also have a power generator, supplying two 25 H. P. locomotives and three traveling cranes, for handling and transporting materials and Copper refining. 100-Kw- 110-vo- ., lt and silver extraction. Electricity has been applied as an auxiliary in various processes for the treatment of gold and silver ores by cyanide, chlorination and amalgamation. While some of these processes are based solely on the faith of the inventor, that a current of electricity sent through his mixture will in some mysterious way produce results that he cannot otherwise obtain, others undoubtedly possess merit, as they are founded on well established laws of electro-chemicaction. These processes are usually conducted with considerable secrecy, and it is impossible to give any reliable data as to the actual results accomplished or the economy of the operations. There is reason to believe, however, that, with the proper combination of chemical, metallurgical and electrical knowledge brought to bear upon this subject, good results may be exGold al pected.

Eldredge, general agent for the Bradley Pulverizer Company, manufacturers of the Griffin mills; is in Salt Lake with his wife and son. Mr. Eldredge has just returned from London and Paris, and while in the two capitals he sold a great many Griffin mills for the mines of South Africa and Westralia. Edito'r J. B.

He says the mines of Bingham are in a condition to maintain an output of 10,000 tons per month, if lead advances to 3. A.
