Meaning

Extraction and separation are operations that can disclose, remove or recover something from a material. They do not necessarily constitute generation of a new kind. Khunrath’s emphatic distinction on page 105 is between bringing precious metal out and bringing it in: recovering what is already present is not metallic transmutation.

Use in the book

The earlier catalogue repeatedly includes extracting among the ways silver and gold are handled. The products may be useful and technically elaborate, but their changed form does not prove that they are the pri-material source. The later objection applies the same issue to the extraction of sulphur from silver and gold. Khunrath grants that extraction, while disputing the inference that the remaining mercury and salt can serve as the seed’s regeneration field.

Page 116 adds an investigative use of separation: distinguish the waters or liquors employed in a preparation from the supposedly independent metallic water said to remain. The concern is whether the product’s apparent character belongs to the metal or to the added medium. Separation thus can help expose a mistaken description even though it does not itself perform the universal reduction.

The explicit exclusion on page 105 has another purpose. Profitable arts can separate silver or gold from minerals and metals, but they are outside the treatise’s present argument about transmutation and genuine particulars. Khunrath does not dismiss them as worthless. He insists upon naming the accomplishment correctly.

This entry therefore complements separation-and-composition in the positive work. Removing excess from Magnesia, separating a metal’s parts, and recovering existing precious metal are all separative acts with different objects. Their shared vocabulary does not establish a shared philosophical status.

Places to read

1599 p. 68Extraction belongs to the ordinary metallic preparation repertoire.
1599 p. 105Separatory recovery of precious metals is expressly excluded from transmutation.
1599 p. 115Extraction of silver’s or gold’s sulphur is granted without granting the opponents’ entire process.
1599 p. 116Separation of employed waters is proposed to test an alleged independent metallic mercury.
1599 p. 117Separated essential parts remain things principiated.

Translation in this edition

“Extraction” should not automatically imply removal of a chemically pure modern component. “Bringing out” on page 105 is Khunrath’s own conceptual contrast and should remain visible where profitable recovery is distinguished from alleged change of kind.

Source note

The phrase bringing out rather than bringing in belongs to the body, not to the modern editor’s explanatory note. It provides unusually direct primary evidence for Khunrath’s distinction between recovery and transmutation.
