Library topics
Testing and Technology
A step-by-step overview of the laboratory test, from preparing a representative sample to analyzing the solution and tailings and selecting conditions for an industrial trial.
Read articleOre Preparation
Why representative sampling, crushing, mixing, splitting, and controlled grinding determine the reliability of a laboratory gold-leaching test.
Read articleTesting and Technology
How to interpret a JinChan laboratory test: initial gold grade, pregnant solution, solid residue, leaching kinetics, result repeatability, and consistency of analytical data.
Read articlePlant Practice
How to move from a JinChan laboratory test to a larger-scale trial: what data must be retained, what must be monitored, and why a laboratory result cannot automatically be treated as industrial operating conditions.
Read articleReagent Consumption
How JinChan working concentration differs from actual consumption in kg/t, what reference values the manufacturer provides, and why dosage must be verified on the specific ore.
Read articleOre Properties
Why the same reagent can deliver different recovery and consumption on different gold-bearing ores, and which material characteristics should be considered before selecting JinChan conditions.
Read articleCopper in Ore
What to consider when testing JinChan on copper-bearing gold material: head analysis, Au and Cu monitoring, reagent concentration, solution, and solid residue.
Read articleArsenic in Ore
What arsenic and arsenopyrite mean in gold-bearing material, why an As assay alone cannot predict recovery, and how to plan a JinChan test.
Read articleJinChan and NaCN
What direct JinChan versus NaCN tests on the same ore show, and why similar recovery does not establish complete technological equivalence.
Read articleTest Practice
A practical method for comparing JinChan regimes, or JinChan and a reference reagent, on one representative gold-bearing ore sample.
