When tailings deposition ceases, there will be an initial period in which the water quality within the pond will require monitoring and treatment. During this time, the tailings pond will be pumped to a low level to assist the tailings surface to gain strength. Tailings Storage 2 was decommissioned for tailings deposition in 2005.

The mine purchased several Bredel hose pumps to address pump maintenance and flocculant wastage problems. The hose pumps' inherent corrosion resistance allows the mine to pump pure flocculant into the discharge lines and holding tanks. With no need to add water, the mine is saving money in water usage, process downtime, and maintenance costs.

Mar 11, 2018· The Cadia Gold Mine in New South Wales has been temporarily closed after the failure of a retaining dam on a tailings pond on Friday 9 March 2018. Tailings ponds are used to store sediment-laden waters from mines; such waters typically contain a high proportion of fine silt and clay particles, which take time to settle out of the water.

Hazardous Properties. Toxic chemicals used to extract the valuable materials from the ore, such as the cyanide used in gold mining, remain in the tailings at the end of the process, and may leach out into ground water. Rock may naturally contain dangerous chemicals, such as arsenic and mercury, which leach into water much more readily after rock has been ground up and exposed to the wind and ...
