Precious metals recovery

Technical Product GuidePrecious Metal Recovery System (PMRS)

INTRODUCTIONTetronics 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 QUESTIONSWHAT 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.
