The most efficient means to acquire these metals is to search for where they are found in greatest abundance, and then mine those deposits. Then, suddenly, a little over 100 years ago, the dynamics of precious metals mining began to change, for the first time in more than four millennia.

The list of environmental concerns that can be connected with rare earth elements is not a brief one. Throughout the cycle of mining processes that rare earth elements go through, there is potential for negative effects on the environment. Extracting rare earth elements begins with mining. This is followed by the refining process, and then ...

Precious Metals. The anodes used in refining base metals — nickel, copper, lead—by electrolysis usually contain gold, silver, platinum, palladium, etc., as well as selenium and tellurium in some amount. In every case, these metals, being less easily oxidized than the principal metal constituting the anode, are not dissolved by the ...

As silver is often found in conjunction with these or alloyed with other metals such as gold, it usually must be further extracted through amalgamation or electrolysis. Silver mining has been undertaken since early times. As silver is a precious metal often used for coins, its mining has historically

Silver is rarely found alone, but mostly in ores which also contain lead, copper, gold, and other metals which may be commercially valuable. Silver emerges as a byproduct of processing these metals. To recover silver from zinc-bearing ores, the Parkes process is used. In this method, the ore is heated until it becomes molten.

Silver as a Constituent in Other Metals and Ores. Most of the silver produced today is a byproduct of mining copper, lead, and zinc. The silver occurs within the ores of these metals in one of two ways: 1) substituting for one of the metal ions within the ore mineral's atomic structure; or, 2) occurring as an inclusion of native silver or a ...
