Once processing is complete up to 40% of the mine tailings can be diverted to a paste plant where it is mixed with cement and used as backfill material for underground mine voids, which reduces the volume of tailings delivered to the TSF. We utilise the paste backfill method at our Didipio Mine.

· Tailings are what remains after extracting valuable minerals and metals from mined ore and usually take the form of a liquid slurry comprising crushed rock, water, trace quantities of metals and additives used in processing, such as petroleum byproducts, sulfuric acid and cyanide. Tailings are pumped into surface dams known as tailings storage facilities (TSFs) .

Processing involves crushing the ore into sand to liberate and recover the gold. What's left over is called tailings. Approximately 95% of the tailings are generated from gravity separation methods, which are chemical free and exploit the difference in density between gold and quartz, just as the oldtimers did with their pans and sluices. The remaining tailings is generated via a .

· This is because – during the extraction of the ore at the mineral processing plant – the recovery of the target metal is never perfect. This means that valuable metals can be lost and end up in the tailings. Although metal recovery percentages are getting higher due to more advanced extraction techniques, this was not always the case. Mineral extraction processes in the past (especially ...

· "Gold tailings are materials remaining after extracting the desirable fraction from the uneconomic fraction (gangue) of the ore. Tailings vary, from overburden, which is the waste rock, to other material that encases an ore or mineral body, and which is displaced without processing during mining," explains Loots.
