High chromium media allow copper recovery rates to improve in step with copper concentrate.

The recovery rate for copper increased by approximately 1.0 percentage points; the recovery rate for gold increased by about 1.3 percentage points; and the final grade for copper concentrate increased by at least 0.7 percentage points.

CHALLENGE

Field issues

The corrosive products of exercise steel alter the chemical environment of the mineral plasma and reduce the appearance of copper and gold floats.

SOLUTION

Optimization of programmes

Switch high chromium grinding medium and conduct continuous industrial monitoring.

START WITH YOUR CONDITIONS

Validation of the programme with on-site data

Submitt ore data on ore type, mills and current media, and obtain recommendations for targeted analysis.
