using the DSTP technique (Deep Sea Tailing Process). The technique is chosen because it saves costs compared to the disposal dam technique. The tailings produced by PT Halmahera Persada Legend, which produces dry tailings of 6.1 million tons and slurry with 51.9 million tons, will be pumped into the sea with the DSTP technique.

the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from : % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings. (d) The % Weight Recovery is equal to the % Weight of the concentrate in Table 1. It can also

Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are separated as tailings. However, a significant amount of copper is lost into tailings during the processing; therefore, tailings can be considered …

Say a copper mine produced 1Mt of metal in 1999 at 90% recovery. The remaining 10% of copper, around 111kt, went to tailings. If the average copper price in 1999 was US$1,500/tonne then that 10% represented US$166.5 million of metal. Fast forward 20 years and at today's price, US$5,842/tonne, if that material could be reprocessed and an …
