Purpose and key benefit Designed as a re-selection test tool for mining operations and mineral-processing experiments. Helps you evaluate and refine concentrate separation on-site without complex equipment. Who it’s for Suitable for beginners learning gold mining and mineral processing, and for technicians performing quick field tests. Durable, portable construction Constructed from durable raw materials that resist drops and wear. Compact, wearable design makes it easy to carry and use during inspections or training. Field-ready performance Functions reliably in locations where electricity is unavailable or transport is difficult, including mountain areas, rivers, and streams. Enables practical testing and sampling in remote conditions. How it solves problems Eliminates the need to return samples to a lab for preliminary re-selection checks. Reduces downtime for decision-making by providing immediate, on-site evaluation. Minimizes risk of damage in the field thanks to impact- and wear-resistant construction. Compatibility and use Compatible with standard mining re-selection procedures and mineral processing experiments. Compact sizing and wearable form factor support hands-on use and easy transport. Typical applications On-site re-selection testing during small- to medium-scale mining operations. Training and practical exercises for beginners in gold mining and mineral processing. Field prospecting and sampling in remote mountain, river, or stream locations where power and vehicle access are limited.
