Alloys Ingot

Minerex AG trades in refined lead ingots from a plant with a production capacity of more than 30'000 tons per year. The plant is equipped with modern refining units and sophisticated laboratory facilities.

Approximately 80% of its total production is exported to Asia and Europe. Each ingot is cast to a customisable weight. The ingots are then packed in bundles of roughly 1200 kg.

Refined lead is manufactured according to our customers’ requested specifications (99.97; 99.98% Pb or Pb 95-97.5% + Sb 2.5-5%).

Analytical Spectra of Refined Lead and Lead-Antimony Alloys - How we Measure and Guarantee Quality

For analyses and quaility control, the iCAP 6500 Duo SSEA spectrometer (Thermo Fisher Scientific, 81 Wyman St., Waltham, MA 02451, USA) is used.

 

The iCAP 6500 Duo SSEA with direct system is controlled via an external PC data station and includes ICP-OES software.

The compact unit is bench mounted, providing a simultaneous ICP spectrometer via an RF induced plasma emission source, a purged echelle polychromator and Charge Injection Device (CID) array detector and includes:

  • 4 channel, peristaltic pump under full computer control feeds a standard glass cyclonic spray chamber via a concentric nebulizer.
  •  solid state, free running 27.12MHz RF generator, provides power for the plasma via a load coil around the standard duo torch configuration.

Duo plasma viewing system provides both axial and radial torch views. Axial and radial viewing positions can be automatically optimized and the viewing system may be automatically changed within a method. The plasma system is contained in an EMC enclosure with safety viewing window and fast access, fully interlocked door.

SSEA <96> Solid State Excitation Accessory allows to analyze the metal samples directly without dissolution.

Lead and Lead-Antimony alloys samples has been measured both directly from metal and after dissolution in HNO3:HF mixture.
