Gemstone Mining

Reduce Energy Costs and Improve Downstream Processes

Register for the 2017 Steinert Mining Expo!

Kimberlite ore material tends to be more contaminated with barren waste rock, and STEINERT makes it easy to implement cost-effective waste rock sorting to improve diamond recovery and prevent damage you find with traditional sorting processes.


The STEINERT NIS with both NIR and HSI (hyper-spectral imaging) technology removes the need for expensive density separation in the pre-concentration process, reducing energy costs and wear on overall equipment.  Followed by the STEINERT XSS-T sorter, the STEINERT system recovers diamonds before the next crushing stage which could potentially damage the material. 

For rough-diamond final recovery, the STEINERT XTS processes even the smallest gemstone material with high recovery rates.  With its high throughput rates, the XTS provides a hands-off solution with the strict security standards required in gemstone recovery systems.
