Book Description
Excerpt from Western Electrician, Vol. 10: Numbers 1-26; January 2-June 25, 1892 In the chamber into which the fine sand falls is a series of jets through which water enters under a pressure of forty pounds. Covering the surface of this chamber are amalgamated plates. The pressure of the water keeps the contents in continual agitation, and the conditions for the instant amalgamation of each particle of the precious metal are favorable. After it has been thrown against the plates till the metal has been captured, the combination of water and sand is allowed to escape at the back of the machine. After the machine has been in operation a given length of time the amalgam is scraped from the plates and the gold is reduced by ordinary methods. The entire machine, as Fig. 1 shows, is mounted on wheels so that it may be run on rails to any desired boint. Power for moving it is provided by the 25 horse power motor that revolves the cylinder sitter and the carrier. Under o'rdinary circum stances the dipper deposits a cubic yard of gravel in.the hopper every minute. It has been 'worked much more rapidly than this. It is stated that it has handled '125 yards in sixty minutes. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
