Project Overview

Introduction / background

large

Dust emissions from tailing dams, end walls and slopes are causing frictions and problems with the local community in the nearby village.

Client asked RST to provide a solution for dust mitigation and we recommended the use of Total Ground Control (TGC).

TGC – is a unique blend of water dispersive co-polymers developed and when applied to the ground surface, TGC crusts and binds the fine particles together creating a matrix that will suppress the movement of fines by both water and wind action

TGC application

large

TGC was diluted with water at a base dilution rate of 3% and sprayed directly over the treatment zone at 2 liters of solution per m2.

Green Marking Dye (GMD) was added at 5 liters / 200 ltrs of TGC to identify treated area

Did several very fine coatings on end walls as difficult application on vertical surface

Results

large

• Reduction in visible dust emissions
• Training of supervisors and employees in the correct application of TGC
• First time ever application on end walls
• Awareness and political statement to the community as a result of the very high visibility of this application
