بيت /silver element ore mining
This rise, coupled with improved techniques for extracting silver from ore, broadened both the quality and quantity of ore that could be exploited. Later improvements, particularly in the late 19th and early 20th centuries, vastly enhanced the base of silver production and accelerated the exploitation of silver as a byproduct of basemetal mining.

History of Metal Mining in Maine. Iron, silver, copper, lead, and zinc were mined, milled, concentrated, and smelted. A sudden drop in prices in 1883 caused most of the mines to close as fast as they had opened. Sporadic activity continued until 1918 when production of base metals in Maine ceased for almost 50 years.
