The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold. This process does not result in gold that is 100 pure, but it does eliminate the bulk of the impurities.

HOW TO MINE SILVER While many technologies exist, Silver is typically mined through a process that uses gravity to break and extract ore from large deposits. The exact method of ore removal used varies by the physical characteristics of the rock surrounding the metal, as well as the unique shape of the deposit. Deposits are often long and cylindrical, which is why they are known as veins. Silver Ore can be strong, made up of solid nuggets, but can also be found in the form of flakes within a more substantial deposit of sand, gravel and other minerals.

Silver is often mined alongside Gold, found together in the form of an alloy called electrum. Other elements regularly mined with Silver include argentite, pyrargyrite, and cerargyrite, the latter sometimes known as Horn Silver. 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.

Mining And Mineral Process Of Gold

Mining And Mineral Process Of Gold

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. Most often, the ore is removed starting at the bottom and working up one layer at a time in a method called overhand stoping. Mines include a network of tunnels and chambers designed to safely raise the pulverized ore up and out in mine cars.
