PitWatch Issue Volume 5, Number 1
The Berkeley Pit is one of the most high-profile examples of the adverse impacts of mining. Although the Berkeley Pit Superfund site is currently in a simple monitoring mode, an extensive amount of work is performed locally related to the understanding and remediation of the Pit and similar systems.
Ongoing projects include:
• treatability studies including metals recovery and in-situ treatment
• use of photocatalytic reactions to enhance water treatment
• demonstration of innovative technologies, such as a Biosulfide process for recovery of copper sulfide, zinc sulfide and sodium hydrosulfide products
• vertical and seasonal characterizations of Pit water
• biological surveys
• remediation using algae
• wall-rock interaction with water
• evaluation of organic carbon in the Pit
• use of neural networks to simulate the Pit system.
