TIN PROCESSING UNIT, KABWE

Zumran along-with its joint venture partner established a 300t/Month feed capacity ELECTRIC ARC SMELTER for production of Tin metal, Ferro-Tungsten, Ferro-Niobium, Lead, Copper, Zinc & numerous other downstream applications in metal recovery and industrial waste.

This Smelting process is a combination of two technological innovations:

(i) Digital Impedance Regulator – used to physically control the electrical power into the furnace. The regulator or ‘PLC’ (Programmable Logic Controller) is to continuously optimally regulate the electrical energy input into the furnace; this is done by incrementally readjusting the positions of the electric arcs generated at the tips of the three electrodes relative to the increasing level of the molten bath.

(ii)Thermodynamic model – used to calculate the ‘recipe’ for how fast the furnace is to be fed and controlled.

Zumran established a strong raw material supply network from:

Zambia – Tin Belt

Rwanda – Tungsten and Tantalite

DRC: Tin – Tungsten and Tantalite

Tanzania – Tin and Tungsten
