Skimming Top Dross
Processing Dross with the MZR
Tapping the MZR
Reusing Recovered Zinc
Applied waste management studies indicate that few hot
dip galvanizers are aware of the true value of the skimmings
created during production.
Traditional recycling practices involve direct resale to
specialist recovery companies or involve limited in-house
recovery by sieving/puddling followed by a devalued sale of
the fines to a trader.
One option is to increase the value of the galvanizing
skimmings by recovering the free zinc available in them
and selling the remaining ZnO powder residues to the zinc
chemical industry.
Data collected over several years indicates
that recoverable zinc from galvanizing
skimmings varies between 60-80% with
an average of about 70% by weight.
Spin galvanizing and tube galvanizing
recoveries average about 80%.
Continuous galvanizing line dross
averages 75-85% recoverable zinc.
In-house Zinc Recovery technology
Referred to as the Metaullics Zinkoff Recovery System (MZR),
the unit is the continuation of technology introduced over 10
years ago.
At the heart of the MZR is a thermo-mechanical device able
to separate free zinc from material mixtures and top drosses.
The MZR is a highly efficient in-house industrial system able
to recover non-ferrous metal from industrial process wastes
and top drosses including, hot dip skimmings and dust,
continuous galvanizing top dross, primary and secondary zinc
refining operations.

MZR-750
Representing proven technology for in-house zinc recovery, the MZR-750 has a waste
processing capacity of 750 kg (1650 lbs.) for each batch process to yield about 400-
500 kg of technically re-usable metal or alloy. The unit is simple to operate and does
not need special, dedicated staff recruitment to man it.
Operating costs are dependent on the costs applicable to the country of operation
but the main cost factors involved are:
Gas: Approximately 25 m³ (800 ft3 max) per burn
(optional oil with approximately 25 litres [6.6 gallons] per burn)
Labor: About 60 minutes per burn
Barrel: Life depends on conditions and usage
MZR Recovered Metal Analyses
The analyses of reclaimed metal from the MZR
reflects the analyses of the process metal the type of
galvanizing being carried out (batch, continuous, wire,
tube, etc).
Experience built over many years of MZR use and operation
in partnership with a wide range of customers indicates that
reclaimed metal is both technically and commercially acceptable
for re-use and re-introduction into the process kettles and baths
from which it originally came.
MZR-1500
The MZR-1500 is the latest development with in-house zinc recovery.
It has been designed and built to specifications requested by large
top dross volume producers such as primary and secondary metal
refiners and alloy producers, continuous galvanizers and large
general hot dip galvanizing groups.
The MZR-1500 has an increased waste processing
capacity of 1500 kg (3300 lbs.). Heating chamber
efficiency is upgraded with a 100 mm thickness
of low thermal mass insulation in the walls and
the heating source is a system of high efficiency
burners. The MZR-1500 is more user friendly, with
greater ease in loading the drum.

Environmental Benefits
Additionally, in-house recovery procedures
are rapidly gaining favor with authorities
dealing with European Commission
Integrated Pollution Prevention and Control
(IPPC) rules and regulations applicable to
waste management. The IPPC recognized
MZR technology as the best available
technique for dross waste management.
In-house recovery reduces
total volumes of waste for
disposal, as well as reduces
the amount transportation
required for virgin zinc and
waste products up to 90%.
Pyrotek’s mission is to provide innovative solutions to customer
needs utilizing our global resources.
