Likewise all auriferous Irony, or Coppery Ores, may be separated by common salt, without a Furnace, or melting fire, and that in the open air (as we said afore where we treated of the poorer Coppery Minera’s, or Ores:) and many hundreds of pounds may be done at one time, and with one labour, and the Gold which is extracted mixtly with the Iron and Copper, may be separated out of the solution, by the moist precipitating way there delivered, and that with a mighty profit and gain, because that same precipitation hurts not in the least either the Copper, or the Iron, as to their malleability.
In like manner may you precipitate the Gold out of any Vitriol water, and that in quantity (when it has any in it): and on such wise too, that the precipitation of the Vitriol shall not at all change ought of its nature; and this is so compendious a way, as that if there were contained no more than one quarter of a Drachm of Gold in 100 l. of Vitriol, yet would not that precipitation be of no use or profit. And on this wise and manner may all other Mineral waters be precipitated.
Moreover, as concerning the means of easily preparing the salt so as to serve for the extracting the Copper, in all Countries, but especially on the Sea Coasts, the Concentration of salt out of the waters, or the Sea will afford you no mean, or obscure Documents touching that thing; which concentration it treated of in the Book Intituled, The Consolation of Navigators.
But forasmuch as there is mention made in this Treatise of a yet other certain Artificial separation of Gold and Silver out of the imperfect Metals, in which, Antimonial scoria have place, in a forenamed extraction, which I would willingly (but as yet have not) delivered; let no body so construe it, as if I either purposely, or carelesly omitted the same: No! The Case is far otherwise, and this is the true reason; seeing this Book now in hand is become more prolix than I intended, I determined with my self to reserve that most profitable process for the following third part, which God willing, I will very shortly publish, till then, I entreat the Friendly Reader to expect or wait for it with a good and patient mind.
Mean while he may acquiesce with these two ways, viz. the dry and the moist, and delight himself herein, and withal take care (as far as in him lies) to have ready by him, some quantity of Salt-petre; for the following third part shall treat of nothing else but the performing and doing of processes by the help of Salt-petre. He therefore that knows how to make it in plenty at a small rate, may hope for so much the greater benefit; and this I judged expedient, to add here for admonitions sake. More shall be discovered (God willing) in the third and fourth following parts.
