## Minestarters Atlas summary

Navachab Gold Mine in Namibia has successfully implemented STEINERT's next-generation dry sorting technology to upgrade its low-grade gold operations. The new multi-sensor sorting system has doubled the ore grade and throughput while reducing operational costs to one-quarter of previous dense media separation \(DMS\) methods.

Reasoning: The implementation of sensor-based sorting technology has significantly improved economic viability by doubling grade and throughput while reducing costs.

- Positive factor: doubling of ore grade

- Positive factor: doubling throughput

- Positive factor: 1/4 of previous operational costs

- Positive factor: environmentally friendly \(dry sorting\)

Facts used in scoring: 2

## Classification and evidence

**Mill Route**

Polarity: neutral

Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

Why it applies: The sorting technology is used to feed downstream CIP \(Carbon-in-Pulp\) plants.

Evidence · text

> the dry sorting plant sorts 200 tph to detect material falling below the CIP plant cut-off grade

## How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
