Extraction of valuable metals from manganesesilver ore

A novel process was developed to extract valuable metals from manganesesilver ore. The preferential dissolution of manganese from the primary materials was achieved. Silver enriched in the residue was leached by complexation dissolution. The highsilica containing product was obtained as the final residue.

US4269622A Recovery of precious metals from difficult ores

Precious metals such as gold and silver are recovered from difficulttotreat ores particularly those containing manganese by lixiviating using an ammonium thiosulfate leach solution containing copper sufficient ammonia to maintain a pH of at least 7.5 and at least 0.05 sulfite ion.

Dissolution of Gold and Silver with Ammonium Thiosulfate from

A novel process was studied to extract economic metals from refractory ores that are difficult to leach with cyanide and ammonium thiosulfate such as the wellknown mangano argentiferous minerals which are minerals of manganese iron and silver. The mineral under consideration originates from the tailings of the Monte del Favor Hostotipaquillo Jalisco Mexico. The sample was characterized

Extraction of valuable metals from manganesesilver ore

A combined novel process was developed to extract valuable metals from manganesesilver ore. The preferential dissolution of manganese from the primary materials was achieved through reductive

A novel process to effectively extract values from a

A novel process was developed to improve the extraction of valuable metals from a manganesebearing goldsilver ore. Before cyanidation a reductive sulfating leaching pretreatment process was adopted to preferentially dissolve manganese from the primary ores according to mineralogy of the ores and possible leaching thermodynamic calculations of manganese minerals and iron scrap was firstly

Process for extracting gold silver platinum lead or

Processes and devices for extracting precious metals particularly gold and silver from mineral ores have been known for thousands of years. Nearly all of these processes have involved the appli ion of high amounts of heat to the ores such that the precious metals would melt and flow from the ores.

Dual Leaching Method for Recovering Silver and Manganese From

Refractory silver in these ores was either 1 intimately as sociated with the manganese 2 chemically resistant to cyanide leach ing or 3 rendered inaccessible to cyanide leach solution by the sur

CN103468947A Hydrometallurgical method for separating and

The invention discloses a hydrometallurgical method for separating and extracting Mn Fe Pb and Ag from silvermanganese ore. The method comprises the following steps: leaching silvermanganese concentrate by hydrochloric acid adjusting the pH value by NH4HCO3 to obtain an ammonium chloride leachate and leaching residues obtained after the ammonium chloride leaching by a hydrochloric acid
