Recovering Iron from Iron Ore Tailings and Preparing Concrete Composite
2019415 Iron ore tailings (IOTs) are a form of solid waste produced during the beneficiation process of iron ore concentrate. In this , iron recovery from IOTs was studied at different points during a process involving pre-concentration followed by direct reduction and magnetic separation. Then, slag-tailing concrete composite admixtures
Utilisation of iron ore tailings as aggregates in concrete
Sustainable handling of iron ore tailings is of prime concern to all stakeholders who are into iron ore mining. This study seeks to add value to the tailings by utilising them as a replacement for aggregates in concrete. A concrete mix of grade 40 MPa was prepared in the laboratory with water–cement ratio of 0.5.
Experimental Study on the Properties of Concrete Mixed with Iron Ore
2016510 The objective of this study is to evaluate the modified performance of concrete with mixing of iron ore tailings in order to solve the shortage of natural sand and make full use of industrial waste. Firstly, the raw materials of mixing were analyzed, and the test ratio was determined. Secondly, the workability and mechanical property of concrete
Utilization of tailings in cement and concrete: A review De
One of the advantages of cement and the cement concrete industry in sustainability is the ability to utilize large amounts of industrial solid wastes such as fly ash and ground granulated blast furnace slag.
