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.
We determine the amount of metals (Au, Pd, Pt, Rh, Ag) in the analysed materials with precision up to parts per million (ppm).
We dry the materials at a temperature of 120°C for 30 minutes, then weigh them to determine the exact mass of each material using analytical scales (with an accuracy of 0.0001g).
We homogenise various materials to the structure required for accurate analysis..
The analysis is conducted using the classical *fire assay* method. In this process, the material sample is melted with flux, causing precious metals to concentrate into a bead. This bead is then analyzed using ICP-OES, XRF, or gravimetric methods. The key advantages of this technique are its high precision in detecting extremely low concentrations (down to tens of ppm) and its ability to determine concentrations of all target elements in a single test.
We use a modern atomic absorption technique to determine the concentration of mercury in air.
We determine the carbon content of a sample by burning it in a controlled atmosphere and measuring the levels of CO₂.
We determine the amount of sulphur (S) in a sample by burning it in a controlled atmosphere.
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:
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.”
We separate ceramic and metal monolithic parts from catalyst housings using hydraulic and/or alligator shears.
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.
