Silver: A native element, mineral, alloy, and byproduct
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 ....
Extraction
The most abundant ores are chalcopyrite and bornite, which contain both copper and iron sulphides. These account for about 80% of the world's known ores. Copper Mining. The following gives an overview of how copper is extracted from its ore and converted into pure metal. Mining The ore is removed from the ground in either open pit or ......
Extraction Of Copper
The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu 2 S+O 2 → 2Cu+SO 2. The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This causes the final product to have a very blistery ....
