| Show the hendryx agitator sak SS wash ilkiew IL view the first account furnished the public by dr W A hendryx on his new cyaniding cyan dyan iding process w which aich is expected to work wonders in I 1 treating republic ores is given in the spokesman review this morning and a picture ture of the agitator which is the chief feat ure of the apparatus is given herewith dr hendryx said yesterday it is a process for the extraction of the precious metals from ores and mill tal tailings lins by means of cyanide of potassium in very dilute solution usually ly one pound of aya nide per ton of water and depositing the metals als so dissolved upon metal plates by 51 the agency of an electric current the es technical feature is the hendryx agitator which cons consists of a cylindrical tank having a conical bottom on the center of the tank is a cylindrical we 1 l 1 in which a vertical shaft revolves carrying two or more screw propellers a and nd driven by a pulley above the tank in the tank outside the well the anode and cathode plates are placed and supplied with current from a small dynamo the ore is crushed to the proper fineness and charged into the agitator together with the water and ch chemicals chemical emica s the revolution of the propellers in the well creates a strong upward current there I 1 immediately starts agitation in the tank and circulation of the whole charge upward through the well and downward through the electrically charged plates thus extraction of the gold and silver by cyanide through aeration of the charge and deposition of the precious metals are going out at the same time when the extraction is completed which takes from four to eight hours a valve is opened in the bottom of the tank and the whole contents discharged into a settler whence the solution is pumped back to a storage tank for further use and the equipped and running the claims made for the process are First that it will extract all the values that any cyanide process can second that it will ill deposit the precious metals in the form of marketable bullion without the intervention of any troublesome precipitating and refining process third that it will make the extraction with less cyanide on account of the perfect aeration and the regenerating action of the electric current fourth that it t will do this work at a much less expense for r plant and operating costs than the ardi nary ry methods fifth that it is especially adapted to handling tailings froni from amalgamation and concentration plants already quipped equipped and running A small plant is now running in the ore testing sting works of C M fassett main avenue spokane wash the feature of the hendryx process for cyaniding cyan iding gold or silver ores is the agitator it is the device which makes possible the thorough aeration of the slimes and the rapid cyaniding cyan iding of the metals the pulp and the water ater are constantly raised by the spiral screw in the central tube shown in the cut reaching the top of the tube the pulp falls back into the main vat and fina ly reaches the bottom of the funnel at its lower end there the pulp is sent upwards again by the spiral screw and thus the process is indefinitely treated the fan like el THE HENDRYX AGITATOR devices shown in the vat aldach at each side of the central tube are the electrodes on which the tae gold and the silver are deposited as pure bullion |
