✨ The Detection Process for Gold Recovery at Chinese Gold and Silver Shops ✨

In China, gold and silver shops adhere to a series of professional testing procedures when recovering gold, ensuring the quality, purity, and authenticity of the gold. The following outlines the specific detection processes and methods employed:

1. Visual Inspection
Purity Markings: Examine the jewelry or gold bars for engravings to verify marks such as “9999,” “916,” or other designations.
Wear Assessment: Observe the item for visible wear, scratches, discoloration, or other damages that may affect its value.

2. Physical Testing
Weight Measurement: Utilize a highprecision balance to weigh the gold, documenting its weight to prepare for subsequent evaluations.
Water Displacement Method: Measure the volume of gold using the water displacement method to calculate its density, aiding in purity assessment.

3. Chemical Testing
Acid Test: Employ different concentrations of acids (such as hydrochloric acid and nitric acid to test the gold, observing the reactions to determine purity. For instance, pure gold will not react in hydrochloric acid.
Flame Test: Place the sample in a flame to observe the metal’s melting behavior, analyzing the reaction to inform on the composition of the gold.

4. Professional Instrument Testing
XRF (XRay Fluorescence Analysis: Utilize XRF instruments to analyze the elemental composition of gold samples, swiftly determining purity and the presence of other metals.
Laser Testing: Employ laser technology to acquire a more detailed analysis of the sample's composition, furnishing precise data.

5. Documentation and Quotation
Data Recording: Systematically document the aforementioned test results to ensure transparency and traceability in the recovery process.
Quotation: Based on the testing outcomes, personnel will provide an appropriate recovery quotation, allowing clients the option to accept or decline.

✨ Conclusion
The above outlines the typical detection processes at Chinese gold and silver shops when recovering gold. Each step aims to ensure the genuine value of the gold, safeguarding consumer rights. It is imperative to select reputable merchants for gold recovery to secure a fair price and a safe transaction experience. ✨
