Merill Crowe Process | Alkaline PLS Filtration |

The Merrill Crowe process is a well proven technology for the recovery of Gold and or Silver from a Cyanide leach solution. Quality front end filtration is essential to the Merrill Crowe process as suspended solids lower the efficiency of the Crowe tower and the zinc electron exchange reaction whilst adding unnecessary mass for the pressure filtration equipment and additional impurity to the

Merrill Crowe Process Offers Effective Filter

The basic process was discovered and patented by Charles Washington Merrill around 1900, and later refined by Thomas Bennett Crowe, working for the Merrill Company. Though there are many, many innovations in the mining and mineral processing arena, to date, no method has yet to be found that is able to compete effectively with the Merrill-Crowe Process for recovering the metallic values from

Merrill-Crowe Process, A Work In Progress

02.01.2018· 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.
