Long considered simply a byproduct of nickel mining and extraction, today, when properly prepared, ferronickel slag and grit material is used in a number of valuable industrial and commercial applications. Dinar Trading has partnered with a European company at the forefront of utilizing ferronickel slag and grit material in an environmentally responsible fashion. Our superior electric furnace nickel recovery techniques yield ferronickel slag and grit material possessing uncommonly low toxicity and radioactivity. |
Due to its low toxicity and radioactivity, Dinar Trading’s ferronickel slag and grit material has a wide range of industrial and commercial uses. These uses include:
|
Ferronickel slag and grit material containing hard and abrasive silicon and iron oxides is an ideal sandblasting material. Purchased primarily by smaller industries, slag is dried and screened to specific granule size (-2.5mm – 1mm) for further bulk resale. |
The use of ferronickel slag in cement production is by far one of its most important uses. In this field, chemical composition (oxides of iron, silicon, aluminum, calcium, etc) is the prevailing characteristic allowing its use as a neutral additive, filler, or final-stage addition to Portland cement. |
With grinding and selective use, ferronickel slag can achieve a granulometry similar to that of clay. Accordingly, recent tests have shown that ferronickel slag can be successfully substituted for non-plastic clay mass in ceramic tiles and bricks. Ceramics using slag additive display increased mechanical strength, decreased shrinkage during drying and burning, lowered water absorbency, and lowered production energy use. |
Through extensive research, ferronickel slag has been found to possess excellent anti-slip and anti-polishing properties when cooled slowly. This makes our low toxicity, low radioactivity slag an ideal additive to asphalt. |
