cip cil verses merrill crowe; 9th wage board of cil; Rotary Drum Filters - 911 Metallurgist. This machine is of the rotary drum filter type, but the filtering medium is applied on the interior of the drum which acts as its own container. The inner surface of the drum is divided into a series of fabric-covered panels, each forming a face of a ...
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). ...
The Merrill-Crowe gold recovery process removes precious metals from a cyanide solution by zinc precipitation. The pregnant solution is first clarified through filters such as horizontal leaf type clarifiers. By using a precoat system (with diatomaceous earth) an extremely clear solution can be produced. The specific design criteria for these ...
Other articles where Merrill-Crowe process is discussed: gold processing: Cyanidation: …steel wool or by the Merrill-Crowe process. In the latter process, the gold-bearing solution is deoxygenated and passed through a filter-press, where the gold is displaced from solution by reduction with zinc metal powder.

These complexes present in the solution are concentrated by an adsorption process with activated carbon, known as CIP, CIL or CIC.

I am compiling some data on Merrill Crowe circuits and are interested in how much zinc dissolves. I would expect zinc to go into solution as gold and silver are precipitated stoichiometrically, but generally a large excess of zinc is added. Generally greater than 5 times stoichiometric zinc is added in the MC.
The evaluation of agitated tank leaching verses CIP and CIL circuits is not as complex as the heap leach-agitated tank leach analysis. CIP and CIL circuits generally have lower capital and operating costs for gold ore bodies than agitated tank leach circuits. Silver ore bodies show better economics with agitated tank leach-Merrill Crowe circuits.
Answer: CIL is carbon-in-leach and CIP is carbon-in-pulp. The difference is that activated carbon is in every tank where gold is leached from an ore slurry with cyanide while CIP has separate tanks for just leaching and then for absorption to activated carbon. …

Today, one of the most popular methods for gold extraction is the Merrill Crowe process. The process can be summarized as follows: The zinc, cyanide and gold ore are mixed. The gold has an affinity to the zinc and cyanide particles and forms deposits on the surface of the zinc. The zinc and gold particles are then filtered out using a filter ...

A CIP study was recently conducted on a composite sample of gold ore that had been collected from the mill discharge of a major Canadian gold mining operation. Gold is currently being recovered at this site in a CCD/Merrill Crowe process, because the ore historically contained high silver values.
The alternative processes, CIP or CIL, have become the preferred process route over the Merrill–Crowe process for medium- and large-scale gold processing plants since the late 1970s, owing to their lower capital and operating costs (see Chapter 31). These lower costs are mainly due to the nonrequirement of the solid–liquid separation step ...

One of these, a systematic comparison completed by DeMent and King (1982) is summarized below. Five separate conventional mills involving both Merrill-Crowe and the CIP processes were compared from an economic viewpoint. The gold concentration on the feed leach liquor ranged from 0.428 to 0.054 oz of gold per ton (14.6 to 1.8 g/mt) of solution.
