Bateman Engineering, through the Atoll group of companies, is a
leader in the metal-recovery plant (MRP) market with major and mobile
installations operating in Southern Africa and elsewhere,
Specialist metal-recovery services are provided to metallurgical processors
and mining enterprises, with the principal activity being the recovery
of metal alloys such as FeMn, FeNiCr, FeCr and SiMn from slag dumps
and other waste streams through two different business models. In the
first model, a toll treatment service offers the processing of slag
dumps (or other waste streams) for a fixed fee per ton, with all recovered
metal handed over to the client. In the second model, processing operations
are undertaken through a joint venture established with the owner of
the slag dump, typically on a 50/50 basis, with Atoll providing know-how,
financing and operational expertise.
The MRPs based on gravity separation utilise the Atoll and Apic jigging
and classification technology. Coal, ore and industrial minerals are
also beneficiated by jigging, while stainless-steel dusts and base-metal
slags are smelted in DC furnaces to recover valuable metals.
Since its formation, Atoll has built 11 major metal-from-slag recovery
plants in Southern Africa capable of processing between 120 and 200
t/h of slag. It has also constructed a 100 t t/h plant for Sweden, a
60 t/h plant for France and has supplied 10 t/h to 35 t/h mobile jigging
plants to clients throughout the world.
The build own, operate (BOO) services, provided through Apic Toll Treatment
(Pty) Ltd, have also been well received by the mining industry. Today
Atoll operates a 150 t/h plant at Transalloys, a 100 t/h plant at Vargön
Alloys in Sweden, a 60 t/h plant at Comilog, France, a 200 t/h plant
at Middelburg Ferrochrome, a 150 t/h plant at Hernic Ferrochrome, and
an 80 t/h plant at SA Ferrochrome. It also has joint venture toll treatment
operations at three other sites in South Africa, one in Brazil, one
in USA, and one in Russia.
These plants enjoy high recoveries combined with a cost effective operation,
producing saleable coarse metal (<2 % slag) at >95 % recovery,
saleable fines (<2 % slag) at > 95 % recovery and ultrafines (<10
% slag) at >70 % recovery.
