The idea, which Edison''s laboratory experimented with during the 1880s and 1890s, was to use magnets to separate iron ore from unusable lowergrade ores. This would mean that abandoned mines could be profitable once again through the extraction of iron from sand at the sites. At the time, iron ore prices had risen to unprecedented heights.
Magnetic Iron Ore Separator Thomas Edison experimented during the 1880′s and 1890′s with using magnets to separate iron ore from low grade, unusable ores. His giant mine project in northwestern NJ consumed huge amounts of money as experimentation plodded forward.
· Edison first became interested in iron mining around 1880, and he received several patents that year for a device that used a powerful electromagnet to pull bits of iron out of a mixture of iron ore and sand. The Edison Ore Milling Company used this device for a few years, but it then went out of business because it could not attract customers for the ore. Edison''s interest was renewed in

Thomas Edison is credited with inventions such as the first practical incandescent light bulb and the phonograph. He held over 1,000 patents for his inventions.
Edison had to invent means for binding the iron into briquettes. It all seemed to come together by 1898. The process was working. He''d cut his costs from 7 a ton to Then the great Mesabi iron range opened in Northern Minnesota. Suddenly iron cost only 3 a ton. By 1899 Edison
"The remarkable process of crushing and magnetic separation of iron ore at Mr. Thomas Edison''s works in New Jersey shows a characteristic originality and freedom from the trammels of tradition.

· The magnetic separators, plagued by screening problems, were concentrating only 47 percent iron—far less than the 66 or 70 percent he needed to match the richness of Great Lakes ore. He was still digesting this information when a stockhouse under construction at Ogden collapsed, killing five men and injuring twelve. Lawsuits alleging negligence were filed by bereaved A
Thomas Edison''s Magnetic Iron Ore Separator . Thomas Edison experimented during the 1880′s and 1890′s with using magnets to separate iron ore from low grade, Figure 1 Rensselaer Polytechnic Institute (RPI) :: Architecture Thomas Edison, FAILURE . At the height of his fame and success, Edison''s magnetic ore separator, for which the powder would now be ready, was sheer
Edison''s arrival on the scene a dozen years later followed his invention of a machine designed to separate nonmagnetic iron ore from sandlike particles in the absence of water. He was heavily engaged in iron ore mining and processing in the east. His electrostatic separator Accepted a thin film of dry particles to pass over an electrically charged drum. He learned that gold, like his iron
Thomas Edison invented the magnetic iron ore separator to try to obtain valuable iron ore from abandoned mines. Knowing that there was still valuable iron in these mines, Edison tried to develop a
Below Dr. Thomas Carroll talking about iron oxide strips, and video/audio tape recording in the first 45 seconds of this video. 3.) Major Types/Formats of Recorders: Wire Recorders The 1940s50s were the golden age of wire recorders, they were a bulky consumer audio recorder. The recorder had been first devised around 1900 as an alternative to wax cylinder recorders. The idea was to record
· Thomas Edison, seen late in life in this video, was the most famous inventor in American history. Though he is best known for his invention of the phonograph and incandescent electric light, Edison took out 1,093 patents in a variety of fields, including electric light and power, telephony and telegraphy, and sound recording. His public image as a homespun, untutored genius actually
Employing remarkable team work and persistence Edison spent much of the 1890s designing machinery to mine and process iron ore at his Ogdensburg, New Jersey ore milling plant, a project that ultimately failed. Explore these events, during the month of March at Thomas Edison National Historical Park. The programs are free and will be held at the Thomas Edison National Historical Park (NHP
Magnetic Iron Ore Separator. Thomas Edison experimented during the 1880′s and 1890′s with using magnets to separate iron ore from low grade, unusable ores. His giant mine project in northwestern NJ consumed huge amounts of money as experimentation plodded forward. Engineering problems and a decline in the price of iron ore [the discovery of the Mesabi iron rich ore deposits near the Great
In 1901 Thomas Edison patented and commercialized NiFe in the United States and offered it as the energy source for electric vehicles, such as the Detroit Electric and Baker claimed the nickel–iron design to be, "far superior to batteries using lead plates and acid" (lead–acid battery).Edison had several patents: Patent 678,722 /1901, Patent 692,507 /1902, and
Thomas Edison was one of the first scientists to take on the challenge. An automobile lover, the renowned inventor knew dramatic improvements to conventional leadacid batteries were needed. Of all his hundreds of inventions from the incandescent light bulb to the phonograph, the project to develop a battery proved to be his most difficult undertaking. Edison decided the new battery would have

He used magnetic separators to cull the iron from sand and other ores. Edison poured a fortune into his iron ore projects well over a million dollars. He bought 145 abandoned mines in the east and was sure he could make them profitable again. But although his technology was advanced and efficient, his venture failed, mostly because iron ore discovered in Minnesota was less expensive to
