Case Studies. For decades, workers at Stevens Creek Quarry dreaded the monthly need to drain and clean out the quarry's settling pond for its excess slurry tailings. Every 30 to 45 days, the entire operation had to shut down for up to eight days while the pond was cleaned, costing up to $80,000 each cleaning. Stevens Creek Quarry.
Bauxite Mining and Processing in Jamaica AN OVERVIEW The Bauxite-Alumina Industry has been a powerful actor on the environmental, social and economic scene in Jamaica since the early 1950s.
