Sequential leaching is a well-established testing procedure, which has been in use since the 1980s. Sequential leaching is a complex procedure. Staff conducting these tests require a high level of mineralogical expertise and strictly controlled laboratory quality control if the test results are to be accurate and reproducible. SGS is backed by a global network of mineralogists, chemists and engineers. Our independent third-party test results are readily accepted by financers worldwide.
SGS strictly controls time, temperature, chemistry and other parameters during sequential leaching. Following an initial mineralogy assessment, SGS experts subject the ore to a sequence of steps:
We then calculate the sum of copper digested during these three digestions and compare the calculated copper to a total copper assay. The data gathered during this testing is important for flowsheet development and pilot plant design.
SGS sequential leaching is a reliable solution to complex copper mineralogy in gold orebodies. Sequential leaching is one of several pressure and ambient leaching treatments that we provide. Contact us early in your planning and proposal stage to determine which leaching procedure will optimize your pay metal recovery and improve your bottom line.
