A demanding gold analysis technique is essential to determine the quality and purity of this priceless metal. To obtain accurate results, this method of analysis includes several important points:
Sample: Since the representation of the sample is critical for determination and accuracy, the procedure begins with a careful separation of a representative sample from the sample. source of gold.
Grinding and homogenization: The collected sample is then coarsely ground to ensure homogeneity. This step is necessary to obtain a representative part of the entire composition.
Fermentation: Chemical digestion is performed on the soil sample, usually involving a combination of acids, to remove impurities and leave only the gold behind.
Precipitation: All remaining impurities are removed after smelting by precipitation, leaving a pure solution containing gold
Filtration: After separating the liquid and solid particles, only the dissolved gold remains in solution.
Quantitative analysis: Several methods are used to determine the amount of gold in solution, including inductively coupled plasma mass spectrometry and flame atomic absorption spectroscopy.
Calibration: The assay procedure involves calibration against accepted standards to improve accuracy and enable accurate estimation of the sample and its gold content.
Reporting: The final stage involves the submission of a comprehensive report with analysis results showing the amount of gold and impurities found. This information is important for many businesses where gold purity is critical, such as the financial, jewelry and mining industries.
Lab duties include metal assays, gold assays and R&D (RandD). The analysis determines the fineness of gold and silver by observing the metal and its quality during the refining process. Emirates Gold uses both spectrometry and conventional fire test techniques in its assay processes..
Our smelting department makes a significant contribution to the production process, turning scrap metal into pellets for our refinery or melting good metal into bars. This section is vital to our day-to-day operations as melting is an important step in almost all Emirates Gold services.
Precious metals such as scrap gold and silver, scrap jewelry or even higher quality gold doré must be refined using a method that separates the valuable gold from the other andquot;waste elements removing unwanted materials and cleaning the product.
Located at the crossroads of many prosperous East-West trade routes, Nairobi has long held a leading position in the global physical gold market, which has only grown stronger in recent years.
