"Cyanide" Quotes from Famous Books
 ... the crushed ore will not mix with the quicksilver, and this is treated to a bath of cyanide, a peculiar acid that melts the gold as water does a lump of sugar. So all of value is saved, and the worthless "tailings" go to the dump. Even the black sands on the ocean beach have gold in them. In the desert also there is gold, which is "dry-washed" by putting the sand ...

... especially among the younger members of the community, to whom a spice of danger is always an attractive element in the fun. But these are clumsy methods of destruction and will not compare with the far easier remedy of poisoning the colonies by means of cyanide of potassium. Dissolve one ounce of the drug in a quarter of a pint of water. This will be sufficient to destroy several nests, but it is a deadly poison, and must be kept in a place of safety. Soak a piece of rag in the fluid, and lay it over the entrance to the nest. There is no occasion ...

... Mr. Greene assumes a partial decomposition at 350 C. is the slight excess of the observed density (14.43) over that corresponding to four vols. (13.375). There is, however, a similar slight excess in the case of the vapor of ammonium cyanide, the same values being respectively 11.4 and 11; and as this compound is volatile at 100 C and, at the same time, is capable to exist at a very high temperature, being formed by the union of carbon with ammonia, nobody has ever, as far as I am aware, maintained that it is completely or partially ...
