![]() ![]() Scheidell, published as a “ Bulletin of the California State Mining Bureau.” This contains an admirable summary of the state of the art at the time of its publication. Clennell and Edgar Smart, have contributed on the chemistry of the process, were among the first to give any adequate idea of its nature.Īnother important contribution to the literature of the subject is the paper of Dr. The papers which Charles Butters, together with John E. Charles Butters, who had left California to erect chlorination works for the Robinson mine at Johannesburg, became interested in the cyanide process, and, after getting the chlorination plant in working order, put up, for working the tailings from the Robinson mine, a cyanide plant which achieved the first large-scale success ever made with this process. Young Janin was one of the first to enter this field, and performed much useful experimental work in the early stages of the history of the process.Īt about the same time, Mr. Among the first American writers on the subject in its modern aspect were two former students of the University of California, Mr. Numerous writers have recently made valuable contributions on the process without exhausting the many complexities of the subject. The fact that many millions of gold have been extracted by the cyanide process, during the last five or six years, from South African tailings which could not be profitably worked by any other method previously tried upon them, lends a peculiar practical interest to this branch of metallurgy.
