Description

Placer gold mining inevitably produces highly turbid processing waters. Five historic paleoplacer mining sites in Central Otago, New Zealand, provided 24 samples which were used in laboratory-based settling experiments. Turbidity was examined in the context of stratigraphy of paleoplacer deposits, their environments of formation, and the groundwater processes that affected the deposits as well as the underlying bedrock. Settling rates were characterised by measuring turbidity levels over time...
