Silver mining - Wikipedia

Silver has been known since ancient times. Silver is mentioned in the Book of Genesis, and slag heaps found in Asia Minor and on the islands of the Aegean Sea indicate that silver was being separated from lead as early as the 4th millennium BC. The silver mines at Laurium were very rich and helped provide a currency for the economy of ancient Athens, where the process involved mining the ore in underground galleries, washing and then smeltingit to produce the metal. Elaborate washing tables still exist at the sit

How is Silver Mined APMEX®

Silver also occurs alongside lead, copper and zinc ores, which is why nearly 50% of mined Silver today is obtained when processing other kinds of ore. Silver is separated from this ore using a chemical process known as smelting. To begin a new Silver mine, a system of multi-layered crosscuts are made.

How the process of mining for silver works - Fraimed

In the early days silver was refined by smelting and cupellation. Later, when the Spanish discovered much richer silver mines in Mexico, Peru and Bolivia, they used the Patio process. The process is attributed to a mining specialist – Bartolomé de Medina who was the first to use a silver amalgamation with mercury to extract silver.

Silver Mining and Refining Education

28-01-2018  Silver is extracted from lead ores in large furnaces, a process called cupellation. Most silver is extracted from ores with a froth flotation process, which was discovered early in the 20 th century. In this process, crushed ore is placed in a bath.

The Silver Extraction Process - athens123

The silver that remained at the bottom of the cupel was run-off and solidified into blocks. Since lead was also valuable, it was recovered by placing the litharge (lead oxide) remaining from the cupellation process into yet a third furnace and heated to 250 degC and air was blown through it. The lead was run-off and formed into rods.

The Mining Process – Waihi Gold

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.
