SHIELD CLEANING

The Challenge

Precious metals are often lost as a result of internal manufacturing processes as metals can adhere to chamber shields or become by-products or scrap. The challenge is to recover the greatest amount of precious metal feasible from shields in order to decrease total cost-of-production. This requires a trusted service partner with the technical capabilities to provide high-value metal recovery services while minimizing manufacturing downtime.

The Solution

TMPI employs advanced and cost-effective methods of shield cleaning and precious metal removal. Our industry-leading process includes innovative chemical cleaning, advanced surface treatments, clean room conditions for cleaning, final conditioning and testing, and onsite logistical support. We collect most precious metals without aggressive mechanical procedures to expedites the cleaning process with high metal returns. Full life-cycle precious metals management lowers the total-cost-of ownership.

Reclaimable Metals

TMPI routinely removes and recovers the following metals:

  • Gold — Au
  • Silver — Ag
  • Palladium — Pd
  • Platinum — Pt
