The silvery ingot and the refined gold contain 99.95 per cent, of the gold issued in the morning for refining, the bulk of the deficiency being in the pots. The amount of gold which goes immediately into work after refining is 97.6 per cent, an average of thirty days8217 refining. The amount of gold left in the silver after reduction from the chloride reaches a maximum of 1 part in 10,000, but is usually from to 13 of this quantity.
The mean fineness of the refined silver was only about 930 prior to the year 1889. In 1889, after the introduction of the iron plates in place of inc, the fineness rose to 948. The subsequent improvement to about 990 was due to the long continued boiling in water in flannel bags. When base gold is refined the amount of copper chloride is large and is probably more easily dissolved in water, so that the resulting silver is finer than if the original bullion contained only a small amount of copper. In the latter case the copper chloride is not easily removed from the chloride cakes.
The silver contained in the gold operated on is distributed in the following manner, the mean results of the five years 1891-95 being given.
The sweep from the condensing chambers amounts to about 3 cwts. per annum, and contains an average of 41 os. fine gold and 157 os. fine silver, which are carried over as globules or volatilised as chloride and condensed.
The mean amount of gold refined per annum during five years 1891-95 was 949,527 os., containing gold 937.7, silver 49.6, and base metals by difference 12.7. The mean assay of the refined gold for the same period was 995.9, and the mean loss of gold in the refining operations for the same period was 0.175 per thousand. The approximate cost of refining per ounce gross weight refined was as follows.
In now billions of ouncesof rough gold were chlorinated. The average assay before refining was.

There are four openings in the cover, three being 6 inches in diameter though two of these only are absolutely necessary. These have lead flanges 1 inches wide and lead-lined iron covers, which are kept in place by stout screws, passing through iron clamps bearing against iron lugs. One opening is used for charging-in and washing out, and the other has attached to its cover two pipes, one for water, which empties the generator of chlorine by forcing it through the second pipe into a second generator, when the charge of the first is exhausted.
A crank shaft connecting with the driving arm fixed at one end of the generator gives three complete oscillations per minute, the cover making an angle of 50 with the floor. This ensures the thorough mixing of the charge.
