Reuse of iron ore mineral wastes in civil engineering

Sep 01, 2008 Removal of overburden to access the ore can pose major problems in storage and reclamation. The stripping ratio (waste-to-ore) for surface mining of metal ores generally ranges from 2:1 to 5:1, depending on local conditions. The iron ore is predominantly mined by opencast mining throughout the country.

The stripping ratio, which is the volume of waste generated for per ton ore extraction. In India, we have faced a huge issue because of it. The amount waste generated is 1.15 to 1.5 times more than the ore extracted. For example, to extract one ton of iron ore the waste produced here is 1.15 tones and in Australia is 0.13 tones. These generated

[PDF] Innovative Development on Agglomeration of Iron Ore

ABSTRACT In steel industry and in mines, a significant amount of ultra-fines waste iron oxides and iron ore fines is generated. Utilizations of these fines are required to reduce the environmental hazards and conserve the natural resources. Some of these fines are normally used in sintering practice. However, sintering has a limitation of accepting ultra-fines materials.
