Mine Environment Management
This is focused in two areas: Mine Environment Management and Treatment of Contaminated Materials.
In Mine Environment Management, we will work in the following areas:
• Strategic design and evaluation of surface waste disposal (rocks, tailings and other wastes)
• Engineering design of tailings disposal sites (traditional impoundment or dry disposal site)
• Environment assessment
• Remediation of existing tailings ponds
• Risk assessment and reclamation of abandoned mine sites
• Hazard control on the site.
In Treatment of Contaminated Materials, our work involves treatment of contaminated soils, sediments and acid generating mine tailings. The primary focus is on providing long term stability using the solidification/stabilization (s/s) method. An in-house developed special binder, named HiFa Bond is used as binding agent.
Experiments on various contaminated materials have been conducted and excellent results are achieved. For instance, the Electric Arc Dust from a steel company and the PCB contaminated soils in a lake, after s/s treatment using HiFa Bond, have achieved over 0.5 MPa compressive strength and met the environment standards with as little as a few percent of binder.
With this special binder, it is possible to treat any kind of wastes: solid, slurry, sludges and liquid. Even toxic materials can be treated by this method. Most importantly, with HiFa Bond, many works which were considered impossible before with the ordinary Portland cement have now become reality.
If you have any problems in waste management or if you want to have more information on the special binder - HiFa Bond, please contact Dr. S. Zou.
