Silver mining - Wikipedia
Once silver ore has been removed from a mine, it is crushed into a fine powder. Silver is commonly extracted from the powdered ore by smelting or chemical leaching. Silver's melting point occurs at 962 °C (1,764 °F). As such, industrial metallurgic processes are needed to prepare silver for commercial purposes.

What is Gold Ore worth? High Grade Mining Ore
For example, lets say that a mine was processing ore valued at 1 troy ounce of gold per ton. This would generally be considered a very high-grade ore, worth mining in most cases. Using this hypothetical value of 1 ozt./ton, each pound of ore would contain approximately 0.0005 ounces of gold. Now let's assume that gold is valued at $1500 per ...

How is Silver Mined | APMEX®
To begin a new Silver mine, a system of multi-layered crosscuts are made. Each cut connects to a central shaft but is kept at a safe vertical distance to avoid collapses. Openings called raises are dug to connect each level. These openings divide the body of ore into blocks. At this point, the Silver mine is ready to begin extraction.

The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
