Slurry Stream Sample Cutter Dimensions for Grinding Circuit Survey

slurry sampler

A good grinding circuit survey (and flotation circuit sampling) is only as good as the sample cutter used for each slurry stream.  Correct sampler volume and opening size insures your sample is representative of the concentrator stream you are testing.  Here is a good suggested design with opening dimensions.  You need to add the handle … Read more

Benefits of using SART on a Zn laded CN solution | Process

In the absence of SART Process, cyanide is consumed by the leaching of cyanide-soluble zinc minerals present in the ore, generating a WAD cyanide-zinc complex (Zn(CN)42-) in solution. This dissolved WAD CN-Zn complex circulates back to the leach in the recycled Barren Leach Solution (BLS), and further reacts with Ag2S in the fresh ore to … Read more

Gold CIL & CIP Gold Leaching Process Explained CCD

cil

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex.  The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where … Read more
