Outotec Dry Tailings Plant product consist of thickening, filtering and dry material handling processes. A Thickener Plant will dewater the tailings from very low solids density to medium and high density. As an example from 5 % w/w solids up to around 65 to 70 % w/w solids for an iron ore tailings.
Because the top lifts of tailing deposition have very low copper contents (due to increased efficiency of copper concentration), Magma pre-strips the top layer in order to get to an economically recoverable zone. In general, the copper content increases with depth (and age) in the tailings pile.
Tailings do not have to be stored in ponds or sent as slurries into oceans, rivers or streams. There is a growing use of the practice of dewatering tailings using vacuum or pressure filters so the tailings

1.0 TAILINGS LEACH PLANT, AN OVERVIEW From inception, Tailings Leach has been developed in three stages. The operation started with leaching of low-grade tailings using strong sulphuric acid followed by solution recovery and cementation of copper. The capacity then was about 1000 tonnes of copper per month.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different
Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were
However, some of the many advantages to using dry stacking of tailings are: Can be used in areas where water conservation is critical and any water loses can jeopardise plant performance. Risks of catastrophic failure and tailings runout as associated with conventional storage facilities are eliminated if the facility is operated as intended.
