Project Objectives:

To assess various technologies for the safe and environmentally acceptable disposal of arsenic trioxide, a by-product of the mining processing operation, that precipitates during the smelting operation as a result of the presence of arsenopyrite
The PE Manganese Terminal was established in the early 1960s, initially as an iron ore export facility and subsequently as one for manganese ore. Modifications to the terminal were necessary to comply with current Environmental Legislation with regards to dust control, groundwater and soil pollution control and stormwater run-off control (surface water pollution control). 

Our Role:

Research of various alternatives for the chemical treatment of the waste product.  The study included an evaluation of various laboratory test programmes.

Conduct a site investigation to quantify the magnitude and extent of groundwater and soil contamination arising from the manganese loading area. Assist with the development of a strategic plan to re-develop the area, taking cognisance of the levels of contamination and need to remediate certain areas.  Conduct monitoring of the groundwater in the area.
