Presentation Title Water: An increasingly valuable and Challenging Resource for the Mining and Metallurgical Industry to Manage Effectively
Author(s) V. Ramachandran
On-Site Speaker (Planned) V. Ramachandran
Abstract Scope Preservation of water resources will be one of humanity’s biggest challenges in this century.As an industry with major potential impacts on water resources and due to the rising cost of process water, the mining and metallurgical industry has a responsibility to contribute to the goal of preserving both the quantity and quality of water available within watersheds we operate in.A hierarchy of options to minimize water usage in the watershed is also critical. Technology is needed to measure parameters of interest,in real-time, as well as to treat water to improve its quality for reuse or release into the watershed. Chemistry related to removal of various constituents will be addressed. This paper will address issues associated with managing water to provide context for a discussion of potential technologies for more advanced water treatment plants and residuals management.
