Study on Utilization of Iron Ore Tailings as Fine ...

It will be a very good impact on the environment if the mining waste is utilized for different purposes. In the case of Kudremukh, with an iron ore content of just 30%, the remaining 70% of waste iron ore tailing had to be dumped in the forested Lakya valley, across which a tailings dam was constructed. This dam now contains over 180 million tonnes of iron ore tailings. 1.1 Objectives ...

Copper tailings in stucco mortars - SciELO

The particle size of the copper tailings sand is quite fine (91% -0.315 mm and 55% -0.16 mm). Moreover, sand tailings have a fineness modulus of 0.54, a very low value. The limit values for fineness modulus are 1.40 to 2.38. The particle size of the crushed sand does not comply with the specifications recommended by the NCh2256/1 standard, for sizes above 2.00 mm. Moreover, the crushed sand ...
