the elmores had formed a company known as the ore concentration syndicate ltd to promote the commercial use of the process worldwide. in 1900, charles butters of berkeley, california, acquired american rights to the elmore process after seeing a demonstration at llanelltyd, wales. butters, an expert on the cyanide process, built an elmore process plant in the basement of the dooley building, salt lake city, and tested the oil process on gold ores throughout the region and tested the tailings of the mammoth gold mill, tintic district, utah, but without success. because of butters’ reputation and the news of his failure, as well as the unsuccessful attempt at the leroi gold mine at rossland, b. c., the elmore process was all but ignored in north america.
