WATER MANAGEMENT SYSTEM FOR ORE MINING OPERATION

摘要

Processes of extracting mineral deposits in ore include treating a saline source, e.g., seawater, to reduce a concentration of one or more multivalent ions (e.g., Ca2+, Mg2+, SO42–) dissolved in the saline source by passing the seawater through one or more nanofilters to produce treated saline water while maintain a certain concentration of dissolved monovalent ions (e.g., (Na+, K+ and C1-) in the treated saline water. The treated saline water can be used in an operation to extract minerals from ore such as in a flotation operation to extract minerals from ore, or to consolidate tailings generated from an extraction of minerals from ore, or both.
