Metal halides - Wikipedia
Some low-oxidation state transition metals have halides which dissolve well in water, such as ferrous chloride, nickelous chloride, and cupric chloride. Metal cations with a high oxidation state tend to undergo hydrolysis instead, e.g. ferric chloride, aluminium chloride, and titanium tetrachloride.
Gold as an etching resist - Finishing
Problem is, the gold seems useless in either ferric chloride (some hydrochloric acid added) or peroxide/sulphuric etchants. It always lifts up or becomes perforated with holes. The gold is pulse plated on at anything from 8v to 15v (I tried a lot of experimenting) at 10kHz and 50% duty cycle.
Recovery of Silver, Gold, and Lead From a Complex Sulfide Ore .
RECOVERY OF SILVER, GOLD, AND LEAD FROM A COMPLEX SULFIDE ORE USING FERRIC CHLORIDE, THIOUREA, AND BRINE LEACH SOLUTIONS By R. G. Sandberg 1 and J. L. Huiatt 2 ABSTRACT The Bureau of Mines investigated a hydrometallurgical procedure to re cover gold, silver, and byproduct lead from a complex lead-zinc sulfide ore.
Champleve Enamelwork with Ferric Chloride - Ganoksin
The Ferric Chloride is safer because it does not have dangerous fumes and produces no underbite if used properly. I purchase a 5 pound bottle of the purified lumps. The lumps keep better than either the liquid or the powder. Ferric Chloride does not etch silver.

Copper(II) chloride - Wikipedia
Copper(II) chloride is used as a catalyst in a variety of processes that produce chlorine by oxychlorination. The Deacon process takes place at about 400 to 450 °C in the presence of a copper chloride: 4 HCl + O 2 → 2 Cl 2 + 2 H 2 O. Copper(II) chloride catalyzes the chlorination in the production of vinyl chloride and dichloroethane.
