The electrolytic process was installed in the Philadelphia Mint, and in the San Francisco Mint. It will be used in the New York Assay Office upon the completion of the new building; and the refinery of the New Orleans Mint, where the amount of work is comparatively small, will then be the only government refinery using the sulphuric acid process.
