As the core tool for modern precious metal detection, gold testers are widely used in multiple links of the gold industry, such as gold mining, processing, trading, recycling, and jewelry manufacturing. Different scenarios have varying requirements for the accuracy, speed, and portability of gold testers. This article will introduce in detail the key application scenarios of gold testers in the gold industry chain to help you choose the most suitable equipment.
Suitable Equipment: Handheld XRF Gold Tester (such as the Olympus DELTA series)
Core Requirements: Fast, high precision, resistant to harsh environments
- Ore Preliminary Screening: Quickly detect the grade of gold ores at the mining site to avoid transporting low-grade ores and reduce smelting costs.
- Smelting Process Control: Monitor the composition of gold ingots in real-time after smelting to ensure they reach the target purity (such as 99.99%).
- Impurity Analysis: Detect the content of associated metals like silver, copper, and lead to optimize the purification process.
Case: After a gold mine in South Africa adopted a handheld XRF gold tester, the ore sorting efficiency increased by 40%, and the smelting cost decreased by 15%.
Suitable Equipment: Desktop XRF Gold Tester (such as the Hitachi EA600VX)
Core Requirements: High precision (±0.1%), non-destructive testing
- K Gold Composition Detection: Ensure that alloys like 18K and 14K meet international standards (for example, Au750 = 75% gold).
- Coating Analysis: Detect the thickness of the gold layer on electroplated gold jewelry (such as 3μm gold plating vs. 5μm gold plating).
- Incoming Material Quality Inspection: Avoid purchasing adulterated gold raw materials and reduce production losses.
Case: After a jewelry factory in Shenzhen used a gold tester, the customer complaint rate decreased by 80%, and the brand reputation was significantly enhanced.
Suitable Equipment: Portable Gold Tester (such as the Niton XL5)
Core Requirements: Rapid identification, anti-fraud detection
- Gold Recycling Detection: Determine the authenticity of gold jewelry/gold bars within 30 seconds to avoid accepting gold-plated or iridium-doped gold.
- Pawned Item Evaluation: Precisely measure the fineness of K gold and pure gold to set a reasonable price.
- Old Gold Refurbishment Detection: Ensure that the purity of the melted and cast gold is not affected.
Case: After a pawnshop in Shanghai introduced a gold tester, the number of fraud cases decreased by 90%, and the recycling profit increased by 20%.
Suitable Equipment: High-precision Laboratory-grade Gold Tester (such as the Thermo Fisher ARL QUANT’X)
Core Requirements: Comply with international standards (such as LBMA certification), data traceability
- Gold Bar Warehousing Detection: Ensure compliance with delivery standards (such as 99.99% Au).
- Cross-border Gold Trade: Provide authoritative detection reports to avoid trade disputes.
- Central Bank Reserve Management: Monitor the purity and weight of the national gold reserve.
Case: The London Bullion Market Association (LBMA) requires all delivery gold bars to be tested using certified gold testers.
Suitable Equipment: Small Desktop/Handheld Gold Tester (such as the Innov-X Systems X-5000)
Core Requirements: Easy to operate, immediate display
- On-site Gold Testing for Consumers: Provide immediate detection reports to enhance purchasing confidence.
- Trade-in Service: Transparently evaluate the value of old gold to improve customer satisfaction.
- Brand Image Building: Showcase professional detection capabilities to differentiate from competitors.
Case: After a jewelry store of ZhouXX equipped with a gold tester, the gold sales increased by 30%.
Suitable Equipment: High-sensitivity Gold Tester (such as the Bruker S1 TITAN)
Core Requirements: High precision, tamper-proof data
- Smuggled Gold Detection: Quickly identify tungsten/lead blocks wrapped in gold plating.
- Market Sampling Inspection: Crack down on fraudulent behaviors such as “underweight gold” and “fake K gold”.
- Forensic Appraisal: Provide legally binding detection reports.
Case: In 2023, Dubai Customs seized a batch of “fake gold bars” filled with tungsten inside, valued at over $5 million.
