"The term "refining," although in strictness applicable to all methods by which impure iron is purified, is in practice restricted to one particular operation practised as a preliminary stage in the puddling process, viz., melting pig iron on a hearth, on which the fuel is piled, the combustion being urged by a blast of air, which also partially oxidizes the iron, both as it melts and subsequently; the molten mass when the operation is complete is either run out into moulds, chilled by throwing water on it." — The Encyclopedia Britannica, 1893

This furnace is used to purify a gold concentrate. The gold concentrates, if non-pyritic, are treated in grinding pans in the bottom of which mercury is placed. The amalgam (mercury alloy), after squeezing out the excess mercury, is heated in the retort, to distil (separate) off the rest and leave the gold, which is then melted and cast into bars of gold bullion of varying fineness.

"One of the simplest forms of sluice as used in river diggings in the north-west of America. A rectangular trough of boards, whose dimensions depend chiefly on the size of the planks available, is set up on the higher part of the ground at one side of the claim to be worked, upon trestles or piers of rough stone-work, at such an inclination that the stream may carry off all but the largest stones, which are kept back by a grating of boards about 2 inches apart at a." — Encyclopedia Britannica, 1893
