For lower grade pregnant solutions, a resinbased, carboninsolution or zinc precipitation (Merril Crowe) process, as part of the overall flowsheet design, is suggested. Resin columns, such as the GREX, are good for treating flotation solutions or pregrobbing ores because they are simple to use, affordable and are not fouled by flotation chemicals.

This process is somewhat faster (typically six to 12 hours) than high pH neutralisation, requires no additional reagents, and most importantly, allows all the iron and acid associated with basic iron sulphate to be neutralised with limestone, at a fraction of the cost of lime.

Here is a common and classic merrill crowe process flowsheet with a simple zinc precipitation chemistry. Some of the flows in this design: Too much dilution water is used Zinc dust is added after the pump No mechanical seal is present on the pump to prevent O2 entry.

The oldest method, Merrill Crowe, involves first removing the oxygen from the solution, then mixing a fine zinc powder with it (200 mesh), and recovering the very fine gold precipitate on a precoat filter, since the gold precipitate is very fine, ranging from a few microns to, merrill crowe process flowsheet .

Flowsheet Options. The basic flowsheet choice is between zinc precipitation (MerrillCrowe) (Figure 1) and carbon adsorption (CIP) (Figure 2). Various hybrid combinations of these two options are also considered as a compromise. A detailed description of the processes is not provided here as this is well described elsewhere. (Ref 1).
