In this study, the characterisation of physical and chemical refractoriness of an arsenical silver ore to the extraction of silver by cyanide leaching was investigated. The mineralogical analysis ...

 · Recovery of silver from an oxidised lead. There was a critical zinc level in solution of approximately 1000ppm, above which the silver recovery fell markedly. cyanide and lime consumptions for this ore were high typically 5 kgt and 40 kgt respectively, hence the processing of this particular ore by cyanide leaching is un economic at current silver.

Sol: Gold and silver ores are concentrated by leaching. In this method, we treat the ore with a suitable reagent in which ore is soluble but impurities do not. Thus, impurities are removed by filtration. Among galena, copper pyrites, cinnabar and Argentine, Argentite being silver ore is concentrated by chemical leaching method.

Silver Ore Mineral Deposits Nigeria is one of the few African countries that has silver deposits, though silver is not vastly deposited in Nigeria like other minerals and metals, as it is only deposited in the northern part of Nigeria, namely Kano and Taraba State..
