Comparison of Environmental Impacts of Deepsea Tailings

Comparison of Environmental Impacts of Deepsea Tailings

The amount of tailings generated is dependent on the ore grade, (proportion of valuable minerals in the ore). For example, if the cut-off grade in the ore is 1 % Copper, 99 percent of the total ore would be deposited as tailings. Iron ores generally have higher grades than sulfide or gold ores, often going over 50 per cent or more.

Utilization of Iron Ore Tailings as Raw Material for

Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.

Tailings Dam Breach Analysis A Review of Methods

Dec 02, 2019 The size of tailings retention facilities varies greatly, but a typical tailings dam is likely to have a surface area of between 1 and 10 km 2. This is a far smaller footprint than DSTP where tailings deposition is usually unconfined and only restricted by the local bathymetric features of the ocean floor (e.g., submarine canyons).
