To split the whole project into workable phases

To identify the practical needs of the project

To identify the skeleton labor required to kick start the project

To identify a partner ( Eng. Contractor) competent enough to assist

To come out with the direct costs of the project

Page 3: New Sands Retreatment Plant 2

At the end of the exercise, we must be able to

identify the different phases of the resuscitation programme

to name a partner

quantify the physical requirements of the project

to value the requirements ( specific costs)

to verify the labor we require

to kick-start the reconstruction of the plant

Page 4: New Sands Retreatment Plant 2

The sands retreatment plant refurbishment and eventual operation is the first part of a holistic ‘C’ Mine Revival Plan.

We intend to revive the whole plant, effecting repairs to machinery, replacing broken piping, fitting new pumps and motors

We also intend to repair and replace all electrical wiring and switch gear

Effect repairs to the lifting equipment Re-line the Ball Mill Repair and replace Hydrocyclones and desanding

cones construction of the feed hopper

Page 5: New Sands Retreatment Plant 2

Effect repairs and services to the knelson concentrator

effect repairs to the amalgam barrels and copper plates

Replace the pinion gear

fabricate motor-gearbox coupling

Recondition mill white metal bearings

Repairing of all mill sumps
