Manes' Electric Pulveriser and Amalgamator.

" Mr James Manes, of Colorado, U.S.,' (says the Mining Journal), " has designed an .ejedric puleeriser.and — amalgamating machine for saving the rusty and fine gold, and also quicksilver, hitherto lost in' hydraulic washing for gold. The electric« amalgamator, it is claimed, will save from 50 to 75 per cent of all the gold and quicksilver, which is] thoroughly amalgamated by the rapid action of the electrical steel brushes and steel mullers that revolve inside the steel cylinders in the machine, placing one above the other, and made cone shape, and connected with spouts ; the large end of one cylinder is placed under the bottom of the small end of the nest one, and so on, forming inclined . planes for the sand and crushed ore to run down by its own gravity, which is assisted by streams of water and quicksilver, con* stantly fed into the machine from a hopper on the upper part of the machine; and the powerful current of electricity is con* stantly passing through the sands or ore as it passes from one cylinder to another; and, a3 it is thoroughly mixed at the same time with the quicksilver by the steel brushes, no gold escapes without having been thoroughly amalgamated. The material passes through a moveable iron spout into settling tanks, where the cleaning up is done. The machine only stops when repairs are needed, tail water is used for driving, and only one man is required for each machine. This apparatus can be used in stamp mills for amalgamating purposes, and will supersede the old process of treating gold and silver ores."
