Mine Waste Management

Course Fee: USD 150 Online; USD 300 Physical

Course Duration: 5 days

Course Description

This course explores the principles, challenges, and best practices associated with the management of waste materials generated from mining activities, including tailings, waste rock, overburden, and slag. Emphasizing environmental sustainability, safety, and regulatory compliance, the course equips learners with tools to assess, design, and implement effective waste management systems throughout the mine lifecycle—from exploration and operation to closure and post-closure. It integrates engineering, environmental science, and policy dimensions to support responsible mining and land reclamation.

Course Objectives

By the end of the course, participants will be able to:

1.Identify types and sources of mine waste and their potential environmental impacts.

2.Understand the geochemical and geotechnical properties of mine wastes.

3.Evaluate waste storage, treatment, and reuse technologies.

4.Apply environmental risk assessment and mitigation strategies.

5.Understand legal, regulatory, and social requirements for mine waste management.

6.Design integrated mine waste management plans that include rehabilitation and closure.
