Carrie Everson

Carrie Everson (born Rebecca Carrie Jane Billings; 27 August 1842–1914) invented and patented processes for extracting metals from ore using the flotation process.[1] The Mining Journal noted in 1916 that "as a metallurgist she was a quarter of a century in advance of her profession."[2]

Life

Everson was educated first in Massachusetts but she had been born in Illinois in 1842. She married a doctor, William K. Everson, in 1864. She patented her discovery that if you used fats or oils with an ore then the oils would stick to the metal and not the rock. On her lab bench she used this with gold, copper, antimony, and arsenic ores. She went on to contribute to another patent but never made any money from her discovery. Everson had a son and died in 1914. After the patent had expired others used her methods which she lived to appreciate if not to benefit from.[3] The Mining Journal noted in 1916 that "as a metallurgist she was a quarter of a century in advance of her profession."[2]
