For Injustice reigns everywhere; and this murderous struggle for what they call 'Fraternity, and so forth has a spice of eternal sense in it, though so terribly disfigured! Amalgam of sense and nonsense; eternal sense by the grain, and temporary nonsense by the square mile: as is the habit with poor sons of men.
The stamped ore, in the form of fine sand, is carried by a stream of water over inclined copper plates covered with mercury, with which is mixed a little metallic sodium. Nearly the whole of the free gold is caught by the mercury, for which it has a great affinity, and accumulates as amalgam on the copper plates, from which it is cleaned off every twelve hours.
Procure a piece of flat iron an old spade will do as well as anything insert the amalgam, and, having placed the potato, cut side downwards, thereon, put the plate of iron on the forge, heat up first gently, then stronger, till separation has taken place, when the gold will be found in a bright clean button on the plate and the mercury in fine globules in the potato, from which it can be re-collected by breaking up the partly or wholly cooked tuber under water in an enamelled or ordinary crockery basin.
No tinned iron or copper vessel should be used for holding or panning out amalgam, or dirt containing amalgam; since quicksilver forms an amalgam with tin and copper, and will stick to the sides of a tinned or copper pan.
That moral amalgam which we call society, and which recognises a mutual and perfectly equal condition of dependence, and a common necessity, as the great cementing principles of the human family, had not yet taken place; and it was still too much the custom, in that otherwise lovely region, for the wild man to revenge his own wrong, and the strong man to commit a greater with impunity.
First, never fill the retort too full, give plenty of room for expansion; for, when the heat is applied, the amalgam will rise like dough in an oven, and may be forced into the discharge pipe, the consequence being a loss of amalgam or the possible bursting of the retort. Next, be careful in applying the heat, which should be done gradually, commencing at the top.
"Christianity appeals to self-regard as the motive of our best action," she went on, giving out her words in short sentences, "so there must be a self-regard which is good too good to degrade itself to worldly ends; too good even to be a part of that amalgam the gold of unselfishness and the alloy of selfishness which makes the ordinary motive of the ordinary good man."
Now, you can destroy that mere physical contact without hurting the individual elements, and this community of interest is an amalgam; you can break it up without hurting any one of the single interests combined.
The compound of gold and quicksilver is a soft white substance known as amalgam, utterly unlike either metal. When the amalgam is subjected to heat, the quicksilver is driven off in the form of a vapor, and the gold is left pure. The quicksilver vapor is condensed in a cool chamber and is used again.
This mercury united with both the gold and the silver, making an amalgam. The amalgam, together with the finely ground ore, was put into a "settler," and here the heavy amalgam sank to the bottom and was then strained. The extra mercury was collected, and the amalgam was put into a retort or kettle and heated.
