Most of the quicksilver is then pressed out, and the silver submitted to a burning process, by which the remaining portion of mercury is expelled.
A suitable quantity of quicksilveris perfectly mixed with the mortar; to which are added some muriates, sulphates, and other chemical substances, to facilitate the amalgamation.
When a tube is as thin as that, even a tiny amount of expansion or contraction will make the quicksilver run up the tube or down.
This doughy mass is presently washed clear of all impurities, and is then squeezed in skins or cloths, through the pores of which loose quicksilver is forced, and saved for future operations.
Let us not omit noting the significance of the fact, that a quicksilver mine exists in California.
The quicksilver escapes by sublimation; but its owner does not wish it quite to escape out of his premises, because it is an expensive article.
The amalgam, therefore, being subjected to heat, thequicksilver escapes by sublimation, leaving the gold pure.
It is then pressed on chamois skins, and the quicksilver is separated from the gold by sublimation.
Near the head of the sluice is a vessel, from which quicksilver falls by drops into the box; and it follows the course of riffle-bars, overtaking the gold which takes the same route.
At the end of two hours the mass has taken the consistence of thick cream, when five hundred pounds of quicksilver are put in, and after the barrel has revolved four hours more, the amalgamation is complete.
The quicksilver and amalgam taken from the sluice are put into a buckskin or cloth, and pressed, so that the liquid metal passes through, and the amalgam is retained.
After a time thequicksilver pervades the copper, and gives it a silvery whiteness all through on the under side.
In many millsquicksilver is placed in the battery, two ounces of quicksilver for one of gold; and about two-thirds of the gold is caught thus.
After the sluicing has been in progress a couple of hours, some quicksilver is put in at the head of the sluice, and it gradually finds its way downward, most of it stopping, however, near where it is put in.
The annual yield of our gold mines is about forty millions of dollars, of our quicksilver two millions of dollars.
The quicksilvermay then be rubbed on with a rag; or, still better, it may be dissolved in nitric acid, and the liquid nitrate of quicksilver may be applied with a rag.
The paste is thus dissolved in the water, and the gold, quicksilver and amalgam have an opportunity to fall to the bottom.
The ore from which quicksilver is obtained is a sulphuret.
Near the bottom are horizontal iron arms, which revolve and stir the quicksilver and pulverized quartz together.
In the Enriqueta and Guadalupe mines the quicksilver is condensed in a close iron retort, and the sulphur is absorbed by quicklime.
Quicksilver is used in nearly all quartz-mill sluices.
As to the quicksilver running out, have you so soon forgotten that the air presses upon every body on the surface of the earth, in the proportion of about fifteen pounds upon every square inch?
Now then I understand it,” cried Tom; “the quicksilver runs down the tubes and alters the centre of gravity of the figures, and so makes them tumble over each other.
As the quicksilver is contained in a closed tube, I do not exactly understand how the air can act upon it; and if the tube were not closed, it would of course run out from its weight,” observed Louisa.
They obtained potash from wine lees, soda from sea-plants, and from quicksilver the mercuric oxide which played so interesting a part in the later history of chemistry.
At the lower (negative) surface small globules having a high metallic luster like quicksilver appeared, some of which burned with explosion and flame while others remained and became tarnished.

He became a Captain in his Corps in 1852, but the opportunities in California were so tempting, that he resigned to enter the practice of the law and embark in various business enterprises of railroad building and quicksilver mining.

Quicksilver explained to Perseus how the Three Gray Women managed with their one eye.
At last, he happened to recollect that Quicksilver had spoken of a sister, who was to lend her assistance in the adventure which they were now bound upon.
Perseus looked about him, rather disconsolately, and asked Quicksilver whether they had a great deal farther to go.

He points the instrument at a star, or at the reflection of the sun's rays from a small round piece of glass or a globule of quicksilver several hundred yards away, and ascertains whether the rays are all brought to a focus.
The surface of quicksilver is exactly level and so at right angles to the true direction of the plumb-line or the force of gravity.
Finally, as there seemed to be no other remedy, our old friend Quicksilver was sent post haste to King Pluto, in hopes that he might be persuaded to undo the mischief he had done, and to set everything right again, by giving up Proserpina.
Now, it happened, curiously enough, that, just as the servant was bringing the pomegranate into the back door of the palace our friend Quicksilver had gone up the front steps, on his errand to get Proserpina away from King Pluto.
While he was speaking, Quicksilver seemed to be in search of something; he went stooping along the ground, and soon laid his hand on a little plant with a snow-white flower, which he plucked and smelt of.
The instant I tasted it, King Pluto and Quicksilver came into the room.
Quicksilver accordingly made the best of his way to the great gate, took a flying leap right over the three-headed mastiff, and stood at the door of the palace in an inconceivably short time.
For now I know that thou art he of whom Quicksilver forewarned me, the most prudent of mortals, against whom no enchantments can prevail.
Quicksilver then gave him some further advice how to behave, and bidding him to be bold and prudent, again assured him that, powerful as Circe was, he would have a fair prospect of coming safely out of her enchanted palace.
I know not how many kind things she might have said to the disconsolate king of the mines, had not Quicksilver hurried her away.

We took leave of our friends an hour or two ago, but do not expect to set sail till the afternoon, as they are discharging the quicksilver which our vessel brought, and loading the silver which we carry away.
The next day we visited the works, which are like all others, excepting that here they do not use quicksilver to extract the silver from the lead, but do so by the process of oxidation, by the means of a reverberatory furnace.
The Italian put a quantity of tin into one crucible, and a quantity of quicksilver into another.
Thus he says, that a mine of quicksilver had been recently discovered in Scotland: the fact however, is, that no quicksilver-mine ever existed in any part of Britain.
Had they been aware of the method of distilling the quicksilver ore into a receiver, this imperfect mode of collecting only a small portion of the quicksilver, separated from the cinnabar, would never have been practised.
Cinnabar was occasionally used as an external medicine; but Pliny disapproves of it, assuring his readers that quicksilver and all its preparations are virulent poisons.
This was done by pounding a piece of ore to powder in a little hand mortar, then putting in a drop of quicksilver to pick up the gold, and then evaporating that fluid by holding it in an iron ladle over a fire.

As the quicksilverin the concentrator was squeezed by Harry or Tom, and the blankets washed by them, none but themselves knew what the returns were.
As the pressure on the quicksilver increased it ran through the pores of the leather in tiny streams, until at last a lump of pasty metal remained.
You see, as the stuff in the cradle is shaken, the gold being heavier than the sand finds its way down to the bottom, and every particle that comes in contact with the quicksilver is swallowed up by it.
The ball, which was of the consistency of half-dried mortar was then taken out, and the process repeated again and again until the whole of the quicksilver had been passed through the leather.
And how do you get the quicksilver out of those lumps?
This was squeezed again and again, until not a single globule of quicksilverpassed through the leather.
It thickens the quicksilver, and as it is squeezed through the leather the quicksilver is as it were strained out, and what remains behind becomes thicker and thicker, until, as you see, it is almost solid.
There is what is called an affinity between quicksilver and gold.
The moment gold touches quicksilver it is absorbed by it, just as a drop of water is taken up by a lump of salt.
