is the key step in the recovery process. This recovery begins when the leach filtrate is sent to the carbon columns, CIC-401, via Stream 29. Gold is adsorbed onto the activated carbon. The filtrate is then sent to the elution vessel, V-401, where the elution process begins. The gold is eluted into a water solution from the carbon by the ...

Table 54.1. Summary of Gold Plants and Flow Sheets Discussed in Gold Ore Processing, Second Edition. Implemented with tube autoclaves 1.5 km long and 5 cm inner diameter. Leaching at ambient temperature and 5 MPa oxygen pressure and 0.2–0.5% NaCN; 15 min residence time for 85% recovery.

A relatively low yield during precious metal recovery by heap leaching (50 to 80 %) is associated with a number of reasons, including the difficulty of selecting the optimal process parameters due to the wide range of gold grain sizes: ultra-dispersed (nano-range) — from 10 –9 to 10 –7 m, fine-dispersed (meso-range) — from 10 –6 to 10 –5 m, …

You have been requested to design a process technology for the recovery of gold from a concession of ore having the following characteristics: the ore is a lode ore and it is received as materials passing 25.0 mm.The ore contain gold, silica and magnetite in the ratio of 2: 6: 2.The particle sizes of gold in the ore ranges between 0.5 and 2.3 mm. ...
