Dual Leaching Method for Recovering Silver and Manganese

Less than 10 pct of the silver was extracted when minus 2.5-plus 1.3-cm ore pieces were leached directly with cyanide. However, extractions of 25 to 82 pct of the silver and 65 to 96 pet of the manganese were attained in laboratory column-leach tests using the dual leaching method on equivalent-sized ore pieces from

Extraction of valuable metals from manganese–silver ore

May 01, 2012 1. Introduction. Manganese–silver ore, which has been found mainly in South-eastern U.S, Latin America (Presic and Wey, 1986) and China (Jiang, 1996), has attracted great attention for its importance as a mineral resource, not only for manganese, but also for silver.In recent years, many efforts have been made to develop efficient and economical process to recover manganese and silver

Extraction of valuable metals from manganese–silver ore

Leaching studies with Penicillium in a stirred reactor showed that at low chloride concentration (equivalent to 0.06% NaCl) manganese was leached selectively from the ore, whereas at high chloride

Extraction of valuable metals from manganese–silver ore

A combined novel process was developed to extract valuable metals from manganese–silver ore. The preferential dissolution of manganese from the primary materials was achieved through reductive leaching in dilute sulfuric acid medium with sodium sulfite as the reductant.

Recovery of Silver, Gold, and Lead From a Complex Sulfide

bilized, silver recovery from high-silver ore would be difficult. Similar methods were used by Scheiner (8-10) to extract silver and other metals-from a complex the PbC12 • Without a pre-FeC13 leach, silver extraction with the NaCN solution was about 20 pct. Results of the FeC13 leach tests are listed in table 2.
