At another part of the upper floor a dynamo if).fixed , to supply a powerful current of electricity to the contents of the pan and the stirrers. At the trial on Friday the index showed it' to be working with an output of over 100 amperes at an E.M.E. of five volts, A small percentage of common salt or other chloride is added to the water; the salt beiug deconrposed by the ekctric current, the sodium passes to the mercury, and the chlorine vising through the mass of pulp, dissolves the fine gold it meets with, and forms a chloride of gold. As the pulp circulates in the pan, this chloride comes under the opera tion of tho electric current, and is de composed in turn, the chlorine being liberated to seek more gold, wliilo the gold passes to the mercury cathode thus producing ordinary amalgam. In the meantime my coarser particles of gold that are too large to be dis solved by the.-chlorine gravitate 10- the bottom, and are also taken hoi of by. the mercury. After the <-■ tents of the pan had been kept for; hour at the boiliug point, and stirn by tho revolving arms, subjected :il.<o v to tho electric current, they were drawn off-into an irou trough, except tbo mercury amalgam. iYrwi this ' trough'they were washed out. into a.' v shallow trough or '(shaking table,'' 'having a horizontal longitudinal' movement; its object is to recover any'small'quantity of mercury that mav have got mixed with the pulp, and any pyrites that may be worth subsequent treatment. ' The tu hie was designed by Mr. J, V. Parkes, F.G.S j luspector of Minos. Tho
