Part Three.

From poor ores, pyrites, sand, clay, and various subjects found everywhere, both fixed and volatile ☉ Gold and ☽ Silver can be very easily extracted, precipitated, edulcorated, desiccated, and reduced into a fixed metallic body through a ▽ water/solvent or ℞ aqua regia. In this work, one part of the used nitric acid is good again and to be applied for further use, but partly that which is extracted from the ores with common ▽ becomes too weak for further use because of the much sweet water. Therefore, such must be made good again in another way, as follows:

If one wanted to take the trouble, one could indeed separate the sweet ▽ again from the sharp ▽ or ℞ through abstraction in glass flasks, so that it would be usable again for extraction afterward. But since more time and fire belong to such work than the ▽ itself is worth, one rightfully lets it be and goes a nearer way. For when one wants to win something right through this artistic method of mine, or extraction of gold and silver, one must necessarily extract much ore, sand, or mountain-earth, for which much ▽ and ℞ also belong. Since then half of the strong waters are not poured off from the ore, but the greater part of it remains hanging in or by the ore, which contains just as much ☉ and ☽ as that which is poured off; therefore it must be boiled out of the ore with common warm ▽.
