Smelting Wikipedia
Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

How Is Quartz Extracted? Sciencing
Quartz is extracted from open pit mines. Miners only use explosives on rare occasions when they need to expose a deep seam of quartz. The reason for this is that although quartz is known for its hardness, it damages easily if it is suddenly exposed to a change in temperature, such as that caused by a blast.

The most common ore of mercury is called cinnabar. Its scientific name is mercury sulfide (HgS). In its pure manmade form it''s called vermillion, a pigment much valued by painters. Luckily, we were given a huge chunk of cinnabar for this challenge even though there are large deposits of cinnabar in New Zealand, there were none where we were
Quartz Mining Encyclopedia of Arkansas
Arkansas is one of a small number of places in the world with enough quartz crystals to justify commercial mining. Though the amount of unmined quartz in the state is not yet known, Arkansas does have, in terms of both size and quality, some worldclass deposits of quartz. Quartz is a common mineral that becomes crystallized under extreme geologic pressure. These crystals have been used to
How Is Gold Extracted From Gold Ore? Sciencing
Another process involves ground ore being passed over plates which are coated with mercury. The gold and the mercury form an amalgam, leading to the name of the process, amalgamation. Once the amalgam has formed, it is heated until the mercury gas is boiled off, leaving the gold. The mercury gas is highly toxic and must be handled carefully.
