The gold bearing liquid is then separated from the leached solids in thickener tanks or vacuum filters, and the tailings are washed to remove gold and cyanide prior to disposal. The separation and washing take place in a series of units by a process referred to as counter current decantation (CCD). Gold . Get P

Tailing Disposal - an overview ScienceDirect Topics

If sufficient area is availe close to the plant, by far the cheapest solution to tailings disposal is to pump the tailings from the thickener underflow to a pond or lagoon, where the solids can, over time, settle out to a dense saturated solid bed and the supernatant liquid can be recirculated to the plant as make-up water.
