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