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