History of Silver
| Old World Silver (4000 BC - 1500
AD) | New World Silver (1500 -
1875) | The Rise Of North America
(1876 - 1920) | The Modern Era (1921 - Present)
The Modern Era (1921 - Present)
A variety of advances in the early
part of the last century allowed for increased production
worldwide. This was critical, as many of the high-grade ores
throughout the world had been largely depleted by the end
of the 19th century. These advances included:
Bulk mining methods, both at the surface and underground, capable of handling
large amounts of lower grade base-metal ores that contained byproduct silver.
Refinement of extraction techniques capable of separating various base-metal
concentrates from ores.
Improved techniques in ore separation, notably
froth flotation (post 1910) that allowed for concentration of silver in lead,
zinc, and copper concentrates.
Improvements in electrorefining techniques
allowing for the easy separation of silver and other base metals from refinery
slimes, thus providing an increasingly important source of silver.
Thus,
the explosion in the production of these various base-metal sources throughout
the 20th century led to an increasing output of silver-bearing residue and ultimately,
refined silver. History
