  Selective-Reductive Leaching of Manganese from Low-Grade Manganese Ore ...

  2019731 · Selective-reductive leaching of manganese from low-grade manganese ore using tannic acid as a reductant in acidic media was demonstrated by XRD, SEM-EDX characterization, and batch leaching studies at room temperature. The pH change in the liquid phase before and after leaching revealed that selectivity of manganese over iron …

  A novel process for silver recovery from a refractory Au–Ag ore …

  201441 · Abstract A novel process was developed to markedly increase silver cyanidation performance from a refractory gold–silver ore in Beiya, Yunnan province, China. Before cyanidation, the process employs a pretreatment step that aims at liberating the silver grains by destroying the crystal lattices of manganese minerals.

  Reductive leaching of manganese from low grade Sinai ore …

  2006111 · Abstract Manganese leaching from a low-grade ore (8.52% Mn) from Sinai was investigated by using hydrochloric acid in the presence and absence of hydrogen peroxide as a reducing agent. Sample characterization by XRD showed the presence of a variety of manganese minerals mainly cryptomelane, chalcophanite, pyrolusite, and …
