The chief ore of silver is Argentite. The silver content in these ores is very small (about 1%). Silver is obtained to a small extent from the gold ores in the kolar fields in Karnataka and in the Anantapur mines. Extraction of silver from the Argentite ore . Silver is extracted from the argentite ore by the Mac-Arthur and Forrest's cyanide ...

May 01, 2020· More importantly, it was found that the 24-h sono-cyanidation provides almost equal or better silver recovery (up to 15.5%) than those of the 48-h direct cyanidation. In other words, it appears that the cyanidation time can be considerably reduced without affecting the extraction performance by the use of ultrasound.

By Mac Arthur and Forrest's Cyanide process, Silver can be extracted from their ore. This can also be done by leaching and smelting. Step1: For the extraction, ore A g 2 S is crushed into fine particles. Step2: By the Froth Floatation, the concentration of ore is done. Step3: T he concentrated ore is then treated with NaCN.
