Description

A kinetic study on low grade manganese ore leaching from Tanggamus area by using pineapple skin waste in sulfuric acid condition had been conducted. The objective of this study was to find out the reaction speed controller on the leaching process. A reductive leaching was conducted in a constant temperature with 300 rpm stirring speed, 10 persen solid percentage with temperature, varying doses of pineapple skin use and sulfuric acid concentrations. The kinetic study used Shrinking Core Model (SCM) assumption where silica existing in manganese ore did not react with its solvent. The results showed that pineapple skin waste was able to use as a reduction agent in manganese ore leaching, while leaching speed controller was controlled by product diffusion reaction through unreacted cores.
