Associated Event

27th International Conference on Paste, Thickened and Filtered Tailings
8–10 April 2025 | Swakopmund Hotel and Entertainment Centre, Namibia

Introduction to Tailings Management Fundamentals and Dewatering Strategies for Surface Disposal Course
7 April 2025 | Swakopmund, Namibia

This course will run alongside the main Paste 2025 conference.

Course objective:

Introductory course on tailings management standards, dewatering technologies, key mineralogy considerations, and other important criteria supporting the selection and design of a tailings dewatering and deposition strategy. The course will provide useful insight on life cycle design, construction, operation, monitoring and closure of a tailings storage facility supported by practical case studies. The course is presented in the form of knowledge share from different spheres of practice: from design to lab analysis, to equipment selection and operation, to problem solving and innovation. It is divided in three parts and concludes with a panel and interactive discussion.  

  • Part 1 – Understanding the key objectives and criteria to consider when selecting a dewatering and placement strategy 
  • Part 2 – Dewatering and placement strategy   
  • Part 3 – Managing risks, key concerns and innovative solutions  

Attendees:

Mine owners, consultants, project managers, site managers and suppliers
