Ideally, none of the unwanted mineral particles float, and they remain behind as the flotation tailings.

The flotation tailings, comprising approximately 80% of the total tailings, will be stored in the main dam.

The construction of the facilities to treat the old flotation tailings includes six 40x40 foot cyanidation tanks, a thickener and a holding tank.

The minerals that do not float into the froth are referred to as the flotation tailings or flotation tails.

The natrojarosite residue can be disposed of in a separate settling pond or combined with flotation tailings in the mill-tailings impoundment.

Some slag exhibits pozzolanic behaviour and can be added to Portland cement and used for solidifying flotation tailings for mine backfill.

The construction of facilities to treat the old flotation tailings to permit the recovery of approximately 53,000 ounces of gold in 2008 and 2009 will be completed in July.

The tailings facility includes a 126 m high rockfill dam, a 35 m rockfill stream diversion dam and disposal facilities for 28 Mm3 of CIL, gypsum and flotation tailings.
