More About Tailings & Water Management. Every aggregate or mineral producer who processes rock, crushed stone, sand, coal, limestone, gold, etc. ends up with tailings. Tailings are the unavoidable and undesirable ground rock and process washwater left over from the processing plant after the desired material has been separated.

For tailings, many people know that it can be processed into recycled aggregate. Bridge building materials contain special tailings, which can be soaked under the high corrosion of seawater for more than 100 years. (2) Concrete Fine Aggregate. Tailings can be used for low strength commercial concrete (C15, C20) or asphalt concrete.

Sep 07, 2017· Background. Recent major tailings dam failures have led to an industry-wide review of the design and management of tailings storage facilities. Before the 1960s, mine tailings were often disposed directly into ponds, lakes, rivers or natural topographic depressions, or stored in impoundments supported by earthen dams, without necessarily applying engineering principles (McLeod et al. 2015).
