Common Silver Extraction Methods
The common gold-silver ore extraction process has the following types: 1. Flotation + Flotation concentrate cyanidation. The sulfide ore containing gold, silver and quartz veins is subjected to flotation process to obtain a small amount of concentrate, which is then sent to cyanidation process. Compared with all-sliming cyanidation …
Fire Assay Flux & Litharge Composition
The following remarks on the use of the fire assay fluxes and litharge may serve as an aid in arriving to a correct composition of charges for most cases:. Litharge or red lead is added in the proportion of one or two parts to two of ore; if too much litharge (lead oxide) is used the slags are not clean, as a slag containing lead may mean a loss …

Thiourea Silver Leaching
In a neutral medium (pH 5-7), silver sulfide forms a nonprotective layer on the silver chloride surface. This layer of silver sulfide gradually dissolves in the thiourea. Early workers such as Plaksin and Kozhukhova (1941) used thiourea to dissolve gold and silver in H2SO4 and H2O2. They observed similar leaching behavior for both metals.
