We manufacture MerrillCrowe Plants for the recovery of gold and silver from cyanide solutions. A Merrill Crowe process lets you easily precipitate gold silver previously dissolved by cyanide using zinc dust. Two primary MerrillCrowe Plant sizes are manufactured, a 10 gallon per minute plant (65 tons of solution per day), and a 50 gallon per minute plant (300 tons of solution per day). The ...
gold . INTRODUCTION Zincdust cementation for gold and silver recovery, also wellknown as the MerillCrove process is the one of the most common contact – reducing processes in hydrometallurgy (Nicol et al., 1979). Cementation is the electrochemical precipitation of one metal by using another metal as a reducing agent.

You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide — all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.
