Engineers designing tailing storage facilities are faced with a number of new challenges resulting from the encroachment of both formal and informal housing projects, legislation pertaining to water usage and pollution control, shortages of water for processing, and the requirements for tailing dam closure.
This has resulted in the introduction of new designs for construction of more stable dams, alternative deposition methods, the introduction of non-permeable linings, and the capping of dams to encourage rehabilitation and minimize dust pollution. The shortage of water in Southern Africa has necessitated changes in dam design to minimize water usage by either reducing the amount of water to the dam or increasing the amount of water recovered.
Understandably, new legislation has been passed to regulate the construction and operation of tailing storage facilities. This knowledge resides with few specialists in the industry, and the operators on the mines are sometimes unaware of the consequences of these changes for their operations. In many cases the operations engineer has been misinformed and the need has arisen to get the parties together to discuss the implications of the changes.
Reprocessing of existing tailings adds to the complexity of operating a tailing storage facility, and many new operators have little or no reference material to assist them when planning a retreatment project.
Ultimately, the design must be focused on the future closure of the facility, and this has been further complicated by changes in the minimum environmental requirements.
Industry has requested a tailing seminar for interested and affected parties to share ideas and solutions with their peers. We invite all operations, designers, technology providers, and legislators to get together for what could be a very informative and successful event.
This will cover a broad range of topics including:
