Executive Summary:
Facing significant efficiency bottlenecks and high labor intensity in traditional fire assay, China Minmetals’ Changkuang Testing Laboratory partnered with Qingdao Decent Group. By implementing our tailored semi-automatic fire assay system, they successfully achieved 40% improvement in sample processing efficiency and 30% reduction in labor costs, setting a new benchmark for analytical precision and operational excellence in modern mineral development.
The Challenge: Overcoming Traditional Bottlenecks in High-Volume Assay
In today’s competitive mining landscape, accurate and efficient analytical capabilities are paramount. As mineral resource development scaled, our client, Changkuang Testing laboratory, encountered severe limitations with their manual fire assay processes. These traditional methods proved time-consuming, labor-intensive, and struggled to maintain data stability under the increasing demands of modern production. The urgent need was a systematic technological upgrade to address:
- Efficiency Bottlenecks: Manual handling of crucibles for melting, cupellation, and pouring drastically slowed throughput, making it difficult to cope with rising sample volumes.
- High Labor Intensity & Risk: Repetitive, high-temperature manual operations imposed extreme physical demands on staff, leading to fatigue, potential operational errors, and safety concerns.
- Limited Batch Processing: Their existing setup restricted synchronous processing, severely capping overall laboratory output and competitiveness.
