Mar 21 2016 The top of the de-aerating tower is connected with a dry vacuum pump which maintains a high vacuum within the tower and removes the air released from the solution. Clarified deaeration solution is withdrawn from the bottom of the tower by a single stage centrifugal pump liquid-sealed to prevent re-entry of air through the pump gland.
Jun 01 1992 The hydrometallurgical process for the treatment of gold and silver ores remained unchanged for the first 70 years of this century and consisted essentially of leaching in cyanide solution followed by solid-liquid separation with the solid residues being washed as efficiently as possible and the leach liquor being treated by zinc cementation to recover the precious metals.

Jul 19 2017 Basic Principles For Designing A Vacuum Deaerator For Seawater - posted in Student As part of my final year degree Im designing a water injection system for an offshore platform. Ive got to design a de-aeration tower and have opted for a vacuum deaerator due to the platform operating a non-continuous flaring regime. Im trying to remove Oxygen from the water to prevent corrosion and .
A method for improving the yield of gold and silver from a Merrill-Crowe recovery process where the presence of copper effects yield. The method involves the addition of a substoichiometric amount of ethylenediaminetetraacetic acid in combination with a phosphonate and polyacrylic copolymer scale control agent. The method also reduces zinc consumption and controls scaling in the stripping circuit.
Vacuum deaerators also known as vacuum degasifiers use a vertical pressure vessel multiple vacuum stages and vacuum pumps to continuously remove objectionable gases from liquids. Packed towers supported by powerful vacuum pumps reduce the surrounding vapor partial pressure which promotes the mass transfer from the liquid to the gas phase.
Apr 01 2000 Pregnant solution is treated in a Merrill-Crowe plant to recover gold and silver. The solution is clarified stored and pumped to the top of a Crowe deaeration tower. When the solution is drawn off from the Crowe tower its oxygen content has been reduced to 1 ppm from 5 ppm.

The deaerator eventually installed No 1 Pump Station. Valves on the 762mm pipe from the Weir to the pumping station diverted the full flow to the deaerator structure which was built 60 metres east of the pumping station. It consisted of an elevated tank 6.7 m in diameter and 2.1 m deep containing two deaerator units each capable of treating .

Precious Metals - Gold and Silver. For over a hundred years miners have used dilute alkaline cyanide solutions e.g. sodium cyanide NaCN around pH 10-11 to leach dissolve gold and other precious metals from their ores. The gold is usually in the form of small flakes mixed with other minerals.
