new agreement made with Edison. The Company provided $25,000 to
cover the costs experiments and Edison promised to
"construct special laboratory for the conduct and prosecution
of said experiments.
The phonograph, electrical, and ore milling businesses
provided the financial foundation for the laboratory. was the critical element an
industrial empire rapidly assuming form the inventor's mind. His first separator was designed extract iron
ore, employing powerful magnets divert iron particles from a
falling stream crushed ore.
The Edison Ore Milling Company was formed 1880 to
exploit his new patents ore separation. Edison's
expectations can seen his estimate the yearly business
of the lab with the following companies:
Edison Lamp $10,000
Edison Electric Light $5,000
Edison Machine Works $6,000
Phonograph $6,000
Ore Milling $3,000
." Edison saw the new laboratory the
tool bring the ore milling and phonograph ventures a
successful conclusion.II- 9
that his new laboratory would able perfect a
commercial machine. Edison had devised a
magnetic ore separator because saw profitable business in
the extraction and processing the rare metals used lamp
