In Situ Leaching and Solution Mining: State of the Art and Recommended Research. Summary Report--Phase I.
For Reference Only At Bureau Libraries :175 pages
In situ leaching and solution mining, relatively new techniques for mining and recovering mineral commodities, have shown desirable attributes such as low front-end costs, low overall capital investment, rapid startup, and favorable environmental considerations. This study was undertaken to obtain a comprehensive evaluation of the state of the art and to develop a coordinated research program toward solving the major technological problems confronting the industry. A task force considered four major topics: geological characterization leaching chemistry, fracturing (rubblization), and solution flow. Major problems appear to be (1) lack of adequate methods to fracture and/or rubblize deep ore bodies cost effectively for leaching; (2) lack of knowledge in fundamental leaching chemistry that would permit predicting such factors as mineral dissolution, precipitation, absorption, and ion exchange; and (3) fluid flow measurement and prediction.
