Unquestionably tha Utah Copper, company was the pioneer In th successful trt-a'-ment of low grade copper ore, andfor seversl years haa boon transforming a mountain of 1 to 1 per cent or st Bingham Into a stream -of red metal. It-can readily be recalled that th proposition ot Colonel Jackllng to ope rats this property was ridiculed because ot th eitremely low copper content ot th or, yet during th comparatlTely few year of th company's existence It has paid dividends totaling about tiii.oe8.ooo. Thar Is to be constructed In tha Iron fields ot northern Minnesota a plant that will cost M.000,000, and which will extract Iron from rock that contains only a microscopic amount of th metal, vail recently there was placed In operation m Juneau.

Scattered throughout this region of th country, and throughout much r f tb world, b fact, there are innumerable mountains of low grsde ores, and as a result of the research work In progress with test tubes, retorts, eleotrlo furnaces snd other scientific appliances. It is only a ejuestlon ot Urn when these mountains are transformed Into metals. - Utah Upmost fortunate In still possessing many mines which are yielding Vhtglj grade ores tn fart, "ths drrelopment tot great ore oodles realty has tmt 9wst began but th knowledge that there exist practically inexhaustible supplies of ores that have not been profitable of treatment Is an assurance, together with the advance In the science of metallurgy, that this state will always be noted for its production ot minerals, both base and precious. j |
