Section 27 Money in Minerals
703. Galvanized Iron.—If you can discover a process for galvanizing iron which will save one-tenth of a cent in its present cost, you will, figuratively speaking, sink a shaft into an endless mine of gold, for the amount of galvanized iron now in use is enormous, and the range of its usefulness is constantly increasing.
704. Metal Extractor.—A solution which will precipitate gold or silver from the ore, and thus save immense sums now expended in the crushing of the ore. Such an invention would revolutionize the mining industry, and make the inventor enormously rich. Mr. Edison says: “I am convinced there is not a single abandoned gold claim in the world, where gold has ever been discovered, from which the precious ore cannot be extracted in quantities to pay a big margin of profit over the cost of operation.”
705. Gold Paint.—Henry Bessemer invented gold paint, which remains a secret to this day. At first he made one thousand per cent. To-day it yields three hundred per cent. Here is a chance for the man of brains, as the monopoly lies in a secret and not in a patent.
