Feb 15, 2010 When the ratio of coal to iron ore tailings was over 1:100, the recovery rate of iron kept stable, and the maximum was 88.2%. In case of calculation as only hematite contained in iron ore tailings, 0.8% coal was needed theoretically, which was as much as experimental data.

Mine tailings dams: Characteristics, failure

The ratio of tailings to concentrate is commonly very high, gen- erally around 200:1 (Lottermoser, 2007). Moreover, as the point of peak metal production is surpassed, the extraction of lower grade ore is an established long-term trend (Mason et al., 2010).

Ore vs Tailings What's the difference? WikiDiff

As nouns the difference between ore and tailings is that ore is rock that contains utilitarian materials; primarily a rock containing metals or gems which—at the time of the rock's evaluation and proposal for extraction—are able to be separated from its neighboring minerals and processed at a cost that does not exceed those materials' present-day economic values while tailings is...
