Heap leaching is an industrial mining method to dig out precious metals andpounds from ore. Process of heap leaching. The mined ore is crushed into tiny chunks and heaped on an impermeable plastic and/or clay lined leach pad where it may be irrigated with a leach solution to melt the valuable metals.
Cyanide heap leaching is used for very low quality ore, or sometimes to reprocess waste material from other extraction methods e.g. leftover mine tailings. A large outdoors mound of ore is sprayed with a cyanide solution that drips through the rock over time. The resulting liquid is collected at the bottom, and the gold is chemically extracted. Heap leaching extracts less of the gold
Heap leach cyani dation is a low capital, low operating cost method to recover precious metals from low grade ores and wastes 1 2. ^ Heap leaching has been successfully ap plied to many low grade, oxidized, dis seminated gold ores since the early 1970's.
heap leaching, for example this is not a factor. If they have not been separated, the cost of solid/liquid separation must be included as part of the cost to recover cyanide, and this can be significant, particularly for high clay, slimy or viscous slurries. In most cases, the washed solids will still have to be treated by a detoxification process to remove residual soluble cyanide species

Leaching tests and analysis of the supernatant indicate that residual solutions would not impact groundwater quality. The limited groundwater flow into the pit via fractures K less than 1E 7 m/s and lower K of the consolidated tailings 10E 8 to 10E 9 m/s will minimize potential groundwater flow through the mass of consolidated tailings.
In China, acid heap leaching technology has been used increasingly in hard rock uranium mines. On the other hand, the resulting heap leaching tailings acidic waste water, not only affect the sewage discharging standard, also bring a series of problems to mine geological conditions, land reclamation, etc.
