Keywords—sand; iron ore tailing; compressive strength; flexural strength; reinforced concrete beam I. INTRODUCTION The increasing demand for heavy construction material like steel and iron has resulted in the establishment of many iron ore mining companies. Iron ore tailing is a waste generated from the iron ore industry (vide Figure 1).
The effects of composition, grain size of chromite fines and recycled fines on the compressive strength of the fired and pre-reduced pellets in varying diameters were studied. 6,7) The possibility of pre-reduction of a variety of chromite ores with a low-grade carbonaceous reductant was also examined. 8) These studies have shown that pre ...
The drop test, compressive strength and porosity of sintered pellet samples from plant and laboratory tests were evaluated. Mathematical correlations of the pellet properties (strength and porosity), ore granulometry and sintering parameters were determined using Statistica (ver7), statistical software package.
High MgO content and the dehydroxylation of laterite ore particles lead to poor compressive strength of fired chromium-nickel bearing iron ore pellets at natural basicity.
This paper investigated the strength and deformation behaviors of modified iron-ore tailing through the unconfined-compressive-strength test and the dynamic-triaxial test, which aims to provide a theoretical basis for the application of modified iron-ore tailing in road engineering. The main conclusions are as follows:
The imported vanadium and titanium magnetite with high chrome has a high assimilation temperature (1 335 °C), a bad liquid phase liquidity (liquidity index 1.95), weak strength of binding phase ...
