English translation:generate precipitates in solutions containing metallic ions
Explanation:
That's what it means in Frenglish.
This property is mentioned in wikipedia:
In these analyses, heavy metal (and nonmetal) ions (e.g., Pb(II), Cu(II), Hg(II), As(III)) are precipitated from solution upon exposure to H2S. The components of the resulting precipitate redissolve with some selectivity, and are thus identified.

No idea what they're on about with 'esprits recteurs d'hydrogène sulfuré'. Probably black magic.

The concept of "ion" definitely didn't exist in the XVIIth century.
I don't have the slightest idea about how a "milieu métallique" was referred to at that time...

Notes to answerer
Asker: I wonder about your interpretation of "ions" -- this is a 17th c text (should've mentioned that!), so maybe not the best choice of words?

agree  Nikki Scott-Despaigne: There are some rather old (18th - 19th century) sources using "esprits recteur" http://www.cnrtl.fr/definition/recteur//1 When I saw an eariler post from Niedz, I read it quickly and mistakenly supposed it was something to do with retro olfaction!

  -> Thanks! I thought of some improbable Google Translate invention. Looking forward to placing it in a conversation!

agree  abe(L)solano: Agree. As a Chemist, "forms precipitates with metal ions in solution" sounds more natural to me. Cheers!

  -> Thanks. Actually I don't like "generate"
