76 VICTORIAN MINERALS.—CASE XIII. 
is brought to England from the Continent, and from which the cobalt is 
saved as a by-product. The demand for nickel, to be used in the manu- 
facture of the basis of plated ware, is steadily increasing, while the 
demand for cobalt is daily diminishing, on account of the artificial blues 
introduced for the use of the dyer, calico-printer and papermaker. Still 
our cobalt-ore might be economically used—the saving being moderately 
easy, where it occurs in quartz reefs worked for gold, as at Alexandra 
diggings, where it coats the joints of the quartz with a botryoidal coat- 
ing of considerable thickness—by passing the tailings through settling 
boxes, in which it would settle with the last of the gold, and be in an 
excellent form for remoying gold from tailings by Plattner’s chlorine 
process. The residue would also be of value for the generation of chlo- 
rine in chemical works. After either of these operations the cobalt could 
be saved. A process has been invented and tried in South Australia, in 
which the cobalt is extracted by smelting the ore with copper and, I 
believe, separating the metallic cobalt by liquation; but I have not heard 
that it lias been attended with success.”

Note.— Antimony is generally found in connection with auriferous 
quartz, and is frequently impregnated with specks of gold. Assays have 
shown as much as 8 ozs. of gold and 80 ozs. of silyer per ton.
