Using real time elemental analysis of conveyed ore flows

Summary: Real time analysis of ore quality between the mine and mill provides major benefits to copper mining and processing operations. Prompt gamma neutron activation analysis (PGNAA) is a proven technique that has been successfully applied for real time conveyed flow multi-elemental measurement. The advantage of PGNAA is that it Purchase Gold Ore Processing, Volume 15 2nd Edition. Print Book & E-Book. ISBN 9780444636584, 9780444636706.

Mike D. Adams. Elsevier, Dec 2, 2005 Technology & Engineering 1076 pages. The gold processing industry is experiencing change. As free-milling and oxide ores become depleted, more complex polymetallic and refractory ores are being processed, coupled with increasing pressure for stricter environmental compliance.Laterite ore contributes to about 70% of the world’s land-based nickel resources. Hydrometallurgical techniques such as heap leaching (HL), atmospheric leaching (AL), high-pressure sulfuric acid leaching (HPAL), Caron process, and direct nickel process (DNi) are the most common processes to treat lateritic ore [ 4 ].Recent Progress in Hydrometallurgical Processing of Nickel Lateritic Ore
