II. Customer Core Needs and Kelin Solutions 1. Precise Ash Content Control – Breaking Through Industry Bottlenecks Pain Point: Local gold mines generally face a 30% drop in gold content due to ash contents exceeding 5%. Kelin Solution: Acid washing + ultrasonic activation process: Ash content increased from 4.8% to 2.9% (third-party SGS verification) Exclusive Quality Control Agreement: Each batch includes an ash content burn test video 2. Customized Packaging – Enhanced Branding and Anti-Counterfeiting Pain Point: Humid transportation environments can easily damage packaging and contaminate containers with carbon dust. Kelin Solution: Three-layer composite bags: Moisture-proof aluminum foil + tear-resistant woven layer + custom logo printing Blockchain traceability code: Scan to verify authenticity and production batch (to prevent market diversion) III. Why do customers continue to choose Kelin Carbon? ✅ Improved Gold Adsorption Efficiency: The first batch of 84 tons of carbon helped increase gold recovery from 92.1% to 96.4% (customer-provided measurements). ✅ Visualized Quality Control Throughout the Entire Process: Open Video Monitoring of Key Production Nodes (Crushing → Activation → Screening). ✅ Localized African Services: 72-hour emergency response by engineers stationed in Ghana (spare parts/technical support). ✅ Carbon Recycling Program: Waste Carbon Recycling Service (Activity Retention > 90% after 5 Cycles).
