Laboratory Assaying

Accurately determining the composition of metal-containing waste is crucial for assessing the value of metals. This process is challenging due to the unique composition of materials; during our research, we encounter various metals, their alloys, and impurities. To precisely evaluate the composition, we prepare samples of the materials with the utmost care. In our work, we use the most advanced measurement techniques and equipment, operated by NOVITERA’s team of professionals with years of experience.

Chemical assay (ICP – OES)
  • We determine the amount of metals (Au, Pd, Pt, Rh, Ag) in the analysed material.
  • Form of materials to be analysed: bulk, liquid.
  • Amount of sample required for testing: 100 g, up to 10 g for precious materials..
  • Note: we do not analyse deleterious substances.
Determination of moisture and exact material mass
  • We dry the materials at a temperature of 120°C for 30 minutes and then weigh them to determine the exact mass of each material.
  • The form of the substances to be analysed: bulk, granules.
  • Amount of sample required for analysis: 100 g.
  • Note: we do not analyse deleterious substances.
Sample preparation for analysis
  • We homogenise various materials to the structure required for accurate analysis..
  • The amount of sample required for testing: depends on the type of material..
  • Note: we do not analyse deleterious substances.
Fire assay to determine the concentration of Au, Ag in the material
  • This modernised process has been used in industry for centuries. The material to be analysed is melted with an additional flux. This allows even small amounts of precious metals to coalesce. The resulting metal concentrate is analysed by ICP-OES, XRF or gravimetric methods.
  • The form of the materials to be analysed: bulk materials and metal swarf.
  • The amount of sample required for testing: up to 100 g.
  • Note: we do not analyse deleterious substances.
Measurement of Mercury in the air
  • We use a modern atomic absorption technique to determine the concentration of mercury in air.
  • Form of analysable substance: gas.
  • Note: Mercury levels are not measured at negative air temperatures.
Measurement of Carbon in metal/bulk powders
  • We determine the carbon content of a sample by burning it in a controlled atmosphere and measuring the levels of CO₂.
  • The form of the materials to be analysed: bulk materials and metal swarf.
  • Amount of sample required for the analysis: 10 g.
  • Note: The material must be properly prepared.
Measurement of Sulphur in metal/bulk powders
  • We determine the amount of sulphur (S) in a sample by burning it in a controlled atmosphere.
  • The form of the materials to be analysed:bulk materials and metal swarf.
  • Amount of sample required for the analysis: 10 g.
  • Note: The material must be properly prepared.
XRF spectral analysis

With XRF analysis, the amounts of metals and other elements in the analysed material are determined precisely. During such analysis, surface measurement is performed.

 

Analysable materials:

  • Precious metals: Pd, Pt, Au, Ag ir Rh, Re. Miscellaneous jewellery, electronics, catalysts, slag, ores, sand.
  • Non-ferrous metals: Sn, Pb, Sb, Co, Ni, Cu, Zn, Cr, Ti, W, V, Mo, stainless and tool steel, brass, solder, bronze, tin (soft (100%) and hard (with 5-30% Ag)).
  • Electronics: Ta, Ge, Hf, Nb, Pd, Pt.
  • Other metals: Ge (optics), Te (powder), Bi, Ga (liquid), In.
  • The form of the materials to be analysed: the surface of the different materials or the prepared material.
  • Amount of sample required for the analysis: 100 g.
  • Note: The material must be properly prepared.

Mechanical preparation

In order to efficiently recycle the provided waste, we must carefully sort, disassemble, grind and carry out other necessary steps of mechanical processing that ensure accurate analysis, precise determination of material value and efficient extraction of various metals.”

Catalytic Converter De-canning

We separate ceramic and metal monolithic parts from catalyst housings using hydraulic and/or alligator shears.

Catalyst Ceramic Milling
  • We mill the ceramic parts of the catalysts into a homogeneous fraction from which precious metals can be successfully extracted. During the milling process, a representative sample of the material is taken for analysis.
  • Note: The Material must be dry and free of oil contamination.
Metal Catalyst Milling
  • The metal catalyst monolith is crushed to 5 mm particles using a hammer mill. The dust collection and removal system effectively and reliably separates precious metals from iron.
  • Note: The Material must be dry and free of oil contamination.
Capacitor Milling
  • We mill ceramic capacitors in special ball mills until we obtain particles of 250–500 microns in size. After that, we separate the metal particles from the mixture using the sieving process.
  • Note: The Material must be dry and free of oil contamination.
Sample Preparation for Laboratory Assaying
  • 300 gram samples are ground in a disc mill to a size of 125 microns. The resulting material is mixed in a special mixer, and samples are prepared for laboratory testing.
  • Note: The Material must be dry and free of oil contamination.
Drying
  • We use specialised ovens to qualitatively remove moisture from a wide range of materials.
  • The form of the materials to be analysed: bulk materials.
  • Note: The Material must be dry and free of oil contamination.
Wire grinding and cable stripping
  • When grinding copper wire, we separate copper metal and insulation materials, as well as separate ferrous contaminants from the general product.
  • Note: the material must not be contaminated with oil and/or flammable substances.
Dismantling of the Electronics
  • We dismantle unusable electronic equipment and prepare it for recycling.
  • Note: We do not dismantle electronic products that contain hazardous and radioactive materials.

Melting and Refining

Our state-of-the-art melting furnaces and modern chemical processes ensure high-quality melting of metals and their mixtures, as well as high-quality material composition after purification. NOVITERA uses induction, electric, and gas furnaces for melting and refining. In the largest gas furnace, we can successfully melt 50 kg of silver at a time.

Au, Ag Scrap melting
  • We can melt both larger and smaller quantities of scrap gold and silver, depending on the customer’s requirements.
  • Minimum quantity: Au – 100 g, Ag – 1000 g..
  • Please note: We carry out a free analysis to determine the exact metal composition.
Melting of Precious and other Metals
  • We melt scrap platinum group and other metals.
  • Minimum quantity: 100 g.
  • Note: We assess the feasibility of melting each material individually.
Refining of Au, Ag Metals and Jewellery Scrap
  • We offer gold (Au) and silver (Ag) scrap and jewellery scrap refining services. Refined metal is returned the same day.
  • Minimum quantity: 100 g.
  • Other important notes (e.g., exceptions): Minimum concentration: Gold – 30%, Silver – 80%.
  • We have an official licence from the “Lithuanian Assay Office” to work with precious metals.
  • The service is performed at a pre-arranged time.
Refining of Metals from Electronics
  • Minimum quantity: 5 kg.
  • Other important notes (e.g., exceptions): Minimum concentration:Gold – 0,3 %, Silver – 30 %.
