## Minestarters Atlas summary

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

Reasoning: The document describes the successful implementation of sensor-based sorting technology to upgrade ore grade and throughput at an existing operation.

- Positive factor: doubling of ore grade through sorting

- Positive factor: reduction in operational costs to 1/4 of previous DMS process

- Positive factor: doubled throughput

- Positive factor: environmentally friendly dry sorting process

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 process is used to preconcentrate ore for downstream CIP \(Carbon-in-Pulp\) plant processing.

Evidence · text

> detect material falling below the CIP plant cut-off grade

**Gravity Route**

Polarity: neutral

Definition: Gravity separation forms a material part of the flowsheet.

Why it applies: the document describes a gravity route \("dense media separation"\)

**Multi-Domain Tested**

Polarity: positive

Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed.

Why it applies: 2 distinct composites were tested

## 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.
