1. Technical Product Guide
Precious Metal Recovery System (PMRS)

2. INTRODUCTION
Tetronics plasma recovery technology is widely recognised as the “go–to” technology for metal recovery, having supplied over 90 plasma systems
across 4 continents.
It has been used for decades to deliver rapid returns from the recovery of Precious Metal (PMs), especially Platinum Group Metals (PGMs) from spent
catalysts with class-leading recovery rates and the lowest environmental impact and cost base.

FREQUENTLY ASKED QUESTIONS
WHAT ARE THE TYPICAL RECOVERY
RATES FOR PGMs/PRECIOUS METALS?
We normally guarantee 98% recovery for
Gold, Platinum, Palladium and Rhodium,
though in practise our customers recover
much more than this. It’s worth noting that
we can also recover Rhodium to the same
levels as Platinum and Palladium.
WHAT CAN THE PLASMAROK
®
BE USED
FOR - DOES IT HAVE ANY COMMERCIAL
VALUE?
Yes, Plasmarok
®
has very high compressive
qualities and the possibilities for use are vast.
It’s also classified as a product, not a waste,
within the EU by the UK Environment Agency.
IS THERE FLEXIBILITY IN SCOPE OF
SUPPLY?
Yes, Tetronics is able to supply a turnkey
solution, including a final refining option, or
core equipment only, depending on client
requirements.
WHAT IS THE DELIVERY TIME?
Typically 9-12 months from order.
DOES THE FURNACE HAVE TO RUN
CONTINUOUSLY?
No, in fact many customers shut down over
a weekend. Typical restarting time is 5-6
hours.
WHAT IS THE TYPICAL PLANT
FOOTPRINT?
The plant will be approx. 500m2
(5,400sq ft)
depending on scope of supply.
WHAT ELEMENTS CAN BE RECOVERED?
We have been able, in our previous work
on varying feed streams, to recover a huge
range of metals, including: Ag, Au, Co,
Cr, Cu, In, Ir, Fe, Mn, Mo, Ni, Pd, Pt, Re,
Rh, Ru, Sn and to our collector Metal and
Cd, Hg, Pb and Zn to our off-gas system.
However, we are also able to look into the
recovery of many more metals.
