Since 2006, over 3,000 melts have been successfully performed on a wide range of materials with negligible operational downtime.  Results have been validated by independent experts from Samancor Chrome, by joint studies with the National Technical University of Athens (NTUA), and independent process audits by Ex Mente of Johannesburg.  Further research is planned in cooperation with the NTUA.

Although the main focus of the application of AMRT melt reduction technology is in the conversion of environmentally problematic materials into products that are both inert and have commercial value, virgin materials, such as concentrates derived from current mining operations, can also be processed. 

AMRT’s furnace units are characterized by high-speed chemical reaction rates at high electrical energy efficiencies.

Emulating the speed of AMRT’s furnace activities is the approach taken in the assessment of new materials. That is, wherever and whenever a material arises, AMRT’s engineering team will immediately embark on the steps of:

(i)   A theoretical evaluation, followed by

(ii) A test campaign involving 5t to 10t of material using our 0.5 MVA test furnace facility.

(iii) Fast furnace construction and set-up. Here AMRT designs and assembles its own furnaces and transformers plus all associated equipment.  After which:

(iv)  Fast and reliable process (production-scale) implementation

Thus, in this way, AMRT is associated in all phases of the project – i.e. from initiation to full production scale implementation.

Examples of materials that have been produced by or processed in AMRT’s melt reduction furnaces are:

Copper

Cobalt

Nickel

Tin

Zinc and lead oxide and sulphides

Ferrochromium

Ferromanganese

Ferrotitanium

Precious metal-bearing wastes
