Feed preparation
Representative sampling, crushing, grinding and pulp preparation for testing.
PROCESS FLOWSHEET
From ore testing to industrial application
JinChan operating conditions are selected based on laboratory test results. Reagent dosage, leaching duration, pH and feed preparation depend on the mineralogical composition of the specific ore.
-
01
Sample collection and preparation
Representative ore sampling, crushing, grinding and material preparation for laboratory testing.
-
02
Laboratory leaching
Testing different reagent dosages, process durations, pH and pulp density.
-
03
Results analysis
Determination of gold recovery, reagent consumption and residual gold content in the tailings.
