Summary:

Mining Methods

  • Hydraulic mining


Summary:

Elikhulu and Evander Tailings Retreatment Plant (ETRP) operation, now termed Elikhulu. During December 2018, the ETRP circuit wasincorporated into Elikhulu to ensure more efficient recoveries of gold from the tailings being processed for the next 13 years and also to reduce unit costs of production going forward.

Retreats gold plant tailings at a rate of 1.2 million tonnes per month (including the combined throughput of ETRP).

Combined hydraulic mining will produce 1.16 Mtpm (0.2 Mtpm to ETRP and 0.96 Mtpm to Elikhulu together with the 0.04 Mtpm of RoM tailings, Elikhulu total throughput is 1 Mtpm).

Summary:

The Evander Gold Plant treats ore from Evander No. 8 Shaft and old tailings etc.

There are six SAG mills operating in closed circuit with a hydro cyclone. The milled product is nominally 80% passing 75 microns. The mill section is noncyanide exposed as it utilises non contaminated underground water for dilution and gland service water.

The cyclone overflow is directed, via linear screens, to five thickeners (of which two are utilised for the current throughput). The thickened pulp is transferred to the leach, CIP/CIL, circuit via a surge tank into which liquid sodium cyanide is added. The leach configuration is based on one surge tank, two leach tanks, four CIL tanks and seven leach tanks. Eight of the fourteen flat bottomed tanks are air agitated and six are mechanically agitated. Oxygen is injected into the first mechanically agitated leach tank. The tailings from the leach train proceed to the CIP circuit, consisting of six flat bottomed, mechanically agitated, ........
