Precious Metal Recovery Systems

Penguin precious metal recovery systems are a simple, economical method for reclaiming gold and other precious metals from processing rinse water and drag-out tanks. The metal recovery system recovers an average of three troy ounces per pound. Even with the smallest unit containing just four pounds of resin pay for themselves after their initial use, the company claims. These units, with a pre-filter and a post-filter, effectively produce higher purity rinse water for improved rinse processing re-use. Various pump/chamber combinations provide for small laboratory operations up to 400-gallon large volume tanks.

Non-PFAS Wetting Agents for Decorative Chromium(VI) Plating

This article is based on a presentation given at NASF SUR/FIN 2022, in Rosemont, Illinois, in Session 6, Responses to PFAS / PFOA. It follows the case study of three facilities’ conversion from PFAS-containing wetting agents to non-PFAS equivalents, eliminating PFAS and moving forward with a smaller and more sustainable environmental footprint. The journey of conversion from PFAS-containing wetting agents in both chromic-sulfuric etch and hexavalent decorative plating tanks can be complicated and winding due to deep rooted standard industry practices, as well as state and federal regulations. Outlined here is a clear course of action that led to eliminating PFAS from the facilities’ wetting agent strategies.
