Tailingsfo Hydraulic Mining of Tailings

The tailings dumps were hydraulically mined, reprocessed and stored in an engineered impoundment located 10km south east of Kalgoorlie. From the 60 million tonnes of tailings mined 695,000 ounces of gold was recovered by Carbon-in-Circuit (CIC) and Carbon-in-Pulp (CIP) leach and absorption circuits (Kaltails 1998; Normandy 1998).

Treatment of coal tailings - ScienceDirect

Jan 01, 2013  Raw coal minus 1.0 mm or 0.5 mm in size is usually upgraded by froth flotation, or a combination of flotation and gravity concentration, before dewatering and being added to the products of the coarser coal separation. The tailings slurry arrives at the plant thickener as a dilute mixture of between 5% and 10% solids w/w.
