Hydrometallurgical leaching and kinetic modeling of low

Manganese was leached from a low-grade manganese ore (LGMO) using banana peel as the reductant in a dilute sulfuric acid medium. The effects of banana peel amount, H2SO4 concentration, reaction temperature, and time on Mn leaching from the complex LGMO were studied. A leaching efficiency of ∼98% was achieved at a leaching time of 2 h, banana peel amount of 4 g, leaching temperature of
