How to Operate a Merrill Crowe Precipitation Process

Efficient Merrill Crowe precipitation of gold and silver is dependent upon the proper control of certain physical and chemical properties of the solution. The most important of these properties are listed below: SUSPENDED SOLIDS, such as ore slime and precipitates of calcium carbonate, with hydrates of aluminum, magnesium and iron, present in the pregnant solution before clarification.

Merrill–Crowe process - Wikipedia

The Merrill–Crowe Process is a separation technique for removing gold from the solution obtained by the cyanide leaching of gold ores. It is an improvement of the MacArthur-Forrest process, where an additional vacuum is managed to remove air in the solution (invention of Crowe), and zinc dust is used instead of zinc shavings (improvement of Merrill). ...

Copper and Cyanide Recovery in Cyanidation Effluents

recovery of gold from Merrill-Crowe process cyanide solution, involves two different operations: 1) gold dis-solution, where it is oxidized and dissolved to form Au (I) ion and cyanide complex 2, and 2) precipitation by reduction of metallic gold. In the cyanidation process, free cyanide ions in solution can only be provided at a pH of 9.0.

Cyanide Leaching Of Gold - Mine Engineer.Com

process at the Homestake Mine in Lead South Dakota in 1897 [6]. In 1918, the vacuum de-aeration tank was in-troduced by T.B. Crowe and was incorporatedinto the Merrill process to make the Merrill -Crowe process. This was the removal of dissolved oxygen, which caused zinc passivation making it almost impossible to filter [8].

Merrill-Crowe Process, A Work In Progress

The Merrill-Crowe process has been around since the early 1900’s, when it was discovered that when a cyanide-gold solution had the dissolved oxygen reduced to 1 part per million, gold readily precipitated from solution, as the CN has a stronger attraction to zinc than gold, so it drops the gold and attaches to the zinc, leaving CN-Zn and Au.
