Gas Dispersion Studies at Highland Valley Copper

摘要: Abstract This paper discusses three case studies conducted at Highland Valley Copper mine (HVC) that illustrate operational improvements and insights which resulted from using the McGill University gas dispersion sensors. In first study, superficial velocity (Jg) sensor was used to implement a profiling control strategy for rougher, scavenger cleaner cells in Cu/Mo separation circuit. The data showed 40% reduction of down-the-bank Cu recovery constant Mo operating target profiles. second bubble size analyzer evaluate effect controlling bubbles generated one two flotation columns make up final cleaning stage. results large proportion small (< 1 mm) increased metallurgical response test column significantly compared reference (typical operation) with increasing 3–4 fold while conce...
