About Jingui · High-end quartz material industry base
Quartz materials, from source to production.
Zhejiang Jingui Technology develops high-purity quartz and silica routes from mineral-resource evaluation through purification, powder engineering, quartz components, laboratory testing and production delivery.
Company profile
Mineral resources. Process experience. Manufacturing capability.
Established in 2023, Zhejiang Jingui Technology builds on a predecessor with a Sino-Japanese joint-venture background. Its core team brings more than twenty years of quartz-processing experience to high-purity sand, silica powder and precision quartz components.
Research and manufacturing teams in Zhejiang, Jiangsu and Shandong work with controlled and partner mineral resources. Material development, equipment manufacturing and in-house testing support both product supply and processing projects.
Development path
From established experience to a coordinated industrial network.
The development path connects established quartz operations with new production bases and mineral-resource projects.
- 2023
Zhejiang Jingui established
Zhejiang Jingui Technology was established, building on quartz-processing operations with a Sino-Japanese joint-venture background.
- 2025
Shandong scale-up base
Chengwu Xinda New Materials was established in Shandong to support material production at scale.
- 2026
Shaanxi resource development
A mineral-resource base was established in Shaanxi, with mineral-right bidding and acquisition projects initiated.
- Today
A connected material platform
Zhejiang coordinates the business, Jiangsu supports research and equipment development, and Shandong supports production. Domestic and overseas resources connect this network to the raw material.
Resource assurance
Start with the source, not only the final purity number.
The team has surveyed more than 2,000 quartz resource sites worldwide, comparing mineral characteristics, impurities and purification potential. Controlled resources, partner mines and buffer inventory support a diversified supply network.
5resource & supply nodes
Mining resources, partner supply and inventory capacity across China and Southeast Asia.
Shaanxi · Low-Iron Resource
An identified reserve of approximately 1.0 million tonnes positions this resource as Jingui's principal source for low-iron quartz feedstock. Exploration-right preparations are currently at the public-notice stage.
Shaanxi · Low-Radioactivity Resource
An identified reserve of approximately 100,000 tonnes is dedicated to low-radioactivity quartz feedstock, supporting material routes where radiological control is a critical requirement. Exploration-right preparations are currently at the public-notice stage.
Myanmar
Wholly owned quartz resources with reported reserves exceeding 10 million tonnes. Selected ore supports 6N-grade purification; delivery planning accounts for regional transport conditions.
Henan & Hubei, China
Partner mines across Henan and Hubei cover low-radioactivity and low-iron quartz categories. Each partner maintains stable monthly supply of more than 3,000 tonnes.
Anhui, China
A 20,000-tonne stockyard covers both low-iron and low-radioactivity categories, providing buffer inventory for delivery continuity, batch planning and flexible customer demand.
Myanmar resource · Field record
Our own mineral resource. Control from the source.
Jingui wholly owns quartz resources in Myanmar, with reported reserves exceeding 10 million tonnes. Source screening, laboratory analysis and purification trials identify selected ore for 6N-grade purification.
Source-quality advantage
A long-term resource foundation, under our control.
Ownership brings mineral-resource knowledge and raw-material decisions into the same team. From field selection to laboratory evaluation and purification, we manage the starting material around the requirements of the finished quartz product.
