Mining Waste Management: From Design to Closure

Objectives

This course provides a comprehensive view of waste management in mining projects, with a special focus on the generation and analysis of information relevant to managing waste during the different stages of a mining project in an efficient and environmentally responsible way.

Technical Background

The marked decline in the average ore grade in operating and new mining projects coupled with aging mines and the consequent deepening have led to a significant increase in the generation of mining wastes which must be responsibly handled and disposed. On the other hand, more restrictive regulations and growing concerns of the communities with regards to environmental care and protection have created a complex scenario requiring mining companies to take measures to ensure the stability and safety of its wastes.

In this context, some experts will not hesitate to say that a mining project today is, above all, a waste management project. The success of a project can indeed depend on its ability to adequately solve the problem of waste management. This problem must be tackled at an early stage and, right from the start of the exploration phase, it is necessary to collect essential information to be able to adequately characterize future wastes and their environmental setting and to manage this process correctly. A long-term vision is needed, which takes into consideration the closure of the project, considering that mining waste constitutes the main environmental legacy. The legacy should not become a liability that generates ongoing expenses that could make the entire project unfeasible.

This course will go over the key aspects of waste management during the different stages of a mining project and will provide the participants with practical tools to identify and manage essential information needed to efficiently and responsibly handle waste management.  For this, it is necessary to consider not only waste characteristics but also the environment in which the waste will be managed.

Participants

This course is designed for Geologists, Mining Engineers, Environmental Engineers, staff involved in the exploration and the design of mining projects and the elaboration of closure plans, as well as staff responsible for environmental management and auditing.

Learning Outcomes

At the end of the course, participants will understand the basic concepts of waste management in mining and will be given practical tools to identify and process essential information so as to manage waste in a responsible and efficient way during the different stages of mining projects.

Specific Objectives

  • Identify and analyse the key environmental issues and impacts associated with mining wastes.
  • Identify, quantify and characterize mining wastes associated with different types of projects and mining processes.
  • Analyse the main factors that determine the occurrence of environmental impacts.
  • Design strategies for gathering and analysing the information required to manage wastes in a responsible and efficient way during the different stages of mining projects.
