Hydraulic Mining Tailings

Tailings Reclamation, Hydraulic Mining, Reclamation of ...

One of the most efficient ways of tailings reclamation is hydraulic mining. Our hydraulic mining solutions utilise high pressure pumping systems and specialised equipment to re-pulp tailings deposits, which allows for reprocessing. This, in turn, gives the opportunity to unlock the true value of tailings.

Practical Considerations in the Hydro Re-Mining of Gold ...

Jan 01, 2016  Hydraulic re-mining is generally best suited to reclamation of hydraulically deposited tailings and fine sands. Coarser residues are better re-mined by mechanical means. Mechanical reclamation is an expensive option for finer tailings, and dredging is generally more expensive than hydraulic re-mining, especially where labor rates are low.
