A New Copper Precipitant.

It is a well established fact that Copper held in solution in water can Be easily obtained by using iron as a Precipitant, but as the precipitation Of copper in solution with iron is Comparatively slow and in many instances quite costly, a more active And less expensive precipitant was in Demand. But Thomas Wren, late of Eureka, but now of Reno, seems to Have solved this problem beyond a Doubt, according to the Reno Gazette. Mr. Wren has made the question a study, and, after numerous experiments with different substances Has discovered that copper in a solution in water can be readily thrown Down with alkali. Alkali will precipitate the copper at once, while Iron requires from twenty four hours To several months, depending upon The amount of iron used.
