SGA has profound knowledge and experience and well equipped facilities for the investigation of concentrating characteristics and flow sheet development as well as process optimization for a wide variety of ores.

In addition to iron ores, studies are performed on various raw materials such as: chrome, manganese, zinc, lead, copper, vanadium, niobium, tantalum, silver, gold, mineral sands, phosphorous etc.

Also, investigations are carried out on rejects and recycle materials such as blast furnace sludge, mill scale, various slags, dusts and other waste materials.
These investigations may range from bench scale tests with a few kilograms of material up to pilot scale tests with 0.5 - 10 t/h for crushing, grinding, classification, upgrading, dewatering etc.
