Sodium and cyanide of potassium are frequently used in dressing-plates, but the former should be very sparingly employed, as it will often do more harm than good by taking up all sorts of base metals with the amalgam, and so presenting a surface which the gold will pass over without adhering to.
Otherwise he spoke and wrote trade-English a toothsome amalgam of Americanisms and epigrams. But though the slang changes the game never alters, and Ollyett and I and, in the end, some others enjoyed it immensely. But we did not neglect Huckley. As Ollyett said our first care was to create an 'arresting atmosphere' round it.
"The solution of double cyanide of gold, silver, and potassium, which has been drained from the leaching vats, is passed over the mercury in the precipitating 'box' when the decomposition of the electrolyte by the electric current is being accomplished, the gold and silver are set free and unite with the mercury, and are also deposited on the plates or discs of copper, forming amalgam, which is collected and made marketable by the well known and tried methods.
When we arrived at the Tour-du-Grec, he signed a document by which he promised to pay me two thousand ounces as soon as I should have discovered to him the process of augmenting mercury by one-fourth without injuring its quality, the amalgam to be equal to the mercury which I had sold in his presence at Portici.
Jack Beal, the managing director of the Yukon Amalgam Corporation, and a great friend of John Kars, had spoken with a certainty which carried deep conviction, coining from a man who was one of the most important commercial magnates of the city. "Pap'll kill him sure," he said, in a manner of absolute conviction. "Maybe he won't hand him the dose himself. That's not his way these days.
This amalgam has a common speech, "made up of workshop and barrack slang and of rural dialects seasoned with a few neologisms." Each one is shown to us as a silhouette, a sharp and admirable likeness; once we have seen them we shall always know them apart. But the method of depiction is very different from that of Tolstoi. The Russian cannot meet with a soul without plumbing it to the depths.
Landscape occupies the main part of his compositions, made up by a strange amalgam of the most eccentric details rocks toppling over blue bays, sea-caverns, and fantastic mountain ranges. Groups of little figures disposed upon these spaces tell the story, and the best invention of the artist is lavished on the form of monstrous creatures like the dragon slain by Perseus.
Formerly the amalgam cleaning room was sacred to the mill manager, and on announcing to that official the new instructions he at once tendered his resignation in a tone of offended dignity, immediately followed by that of the mine manager.
The principal point about this mode of treatment is the squeezing out of the mercury, whereby the amalgam goes into the retort in the form of powder, thus preventing the slagging of the iron and enclosure of the gold. The second point of importance is thorough calcining before smelting.
Having got your amalgam clean squeeze it through a piece of chamois leather, though a good quality of new calico previously wetted will do as well. The residue will be retorted gold, which, on being weighed and the result multiplied by 2240 for a 1 lb. assay, or by 1120 for 2 lb., will give the amount of gold per ton which an ordinary battery might be expected to save.
