Mineralogical And Deportment Study Of Gold Using Diagnostic Leaching Experiment

The as-received gold ore samples from Kuala Lipis, Pahang was used in the deportment study of gold using diagnostic leaching experiment. Prior to the design of diagnostic leaching experiment, mineralogical characterization were conducted on the gold ore sample. Physical properties study on rock s...
