Kansanshi Mine, Zambia concentrate grade Optimization

(Shift Metallurgist)

● Created test documents and integrated test results

● Liaised with the Metallurgists

Recommended reagent dosage of Betamin

Project Overview

The project involved optimization of Betamin

Reagent to lower insols in the final concentrate

at the cleaner cells. The presence of high insols in final concentrates attracts penalties to the customer which lead to unsustainable business and lowers company income.

KONKOLA COPPER MINE, JAN 2017 - DEC 2017

Smelter Reverbs Furnace, Zambia

(Project Metallurgist)

Project Metallurgist ensured that:

● He managed the project from inception to completion. There was hourly monitoring daily.

Lead daily meetings and gave updates.

The Lufubu ore was charged accordingly.

Created Test Documents.

Operators were trained.

Project Overview

The project involved determining the fluidity

of locally cheaper flux ore (Lufubu flux ore) and compare it with lime rock. Project work included Liaising with convertor Metallurgists who approved it was not affecting the converter copper kinetics. The fluidity of the Lufubu flux ore was better than the lime rock which was subsequently replaced since we were able to easily attain higher bath temperatures which increased the feed rates and reduced smelting costs.
