Utilization of Iron Ore Waste in Brick Making For the Construction Industry International Journal of Earth Sciences and Engineering ISSN 0974-5904, Vol. 09, No. 02, April, 2016, pp. 450-455
The experiment carried out by Jian et al. (2011) on sintered wall materials reveals that the iron ore tailings and waste can be used very effectively as construction material. The study also showed that due to higher iron content in iron ore tailings and waste rock, the products reduce the sintering temperature and decreased energy consumption.

The project will see almost 18 Mt of low grade, extremely abrasive hematite iron ore turned into a. saleable product for SIMEC in ...
Steel slag and iron ore tailings to produce solid brick Suzy Magaly Alves Cabral de Freitas 1 · Leila Nobrega Sousa 1 · Pollyana Diniz 1 · Máximo Eleotério Martins 2 · Paulo Santos Assis 1
Consequently, for each ton of iron ore processed, about 0.4 tons of iron ore tailings (IOT) are produced [5]. Most are disposed of in tailings dams. Around 1.3 trillion cubic meters of IOT are deposited in 213 tailings dams, of which 39 are the "upstream or unknown" construction type [6], considered dangerous and risky [7].
The volume of tailings discharged worldwide from iron ore smelting processes (i.e., iron ore tailings) has increased dramatically in recent years, and the disposal of this waste poses a substantial ecological threat to soil, and surface and sub-surface water. This threat can be alleviated to a large extent by employing iron ore …
India ranks fourth concerning iron ore production in the world. 1. In 2019, the total world production of iron ore was 2,850 million tons (approx.) with an Indian contribution of around 230 million tons. 2. The unavailability of cost-effective technology for the extraction of iron ore leads to the generation of a huge amount of waste. 3
