Existing Waste Management Practices and Pollution Control for Marine and Coastal Mining

Identifying practices for offshore discharge of mining residuals

Objective

Arctic coastal mining has a long history. Historically, most of these mines discharged their waste rock and tailings into the ocean. The practice of depositing waste rock and tailings from mines into the ocean as well as discharging mining wastewater has the potential to affect the marine environment.

Activities

  1. Inventory Arctic marine and coastal mining operations and planned operations
  2. Identify practices for offshore discharge of mining residuals including waste rock, tailings, sediments and water.
