Magnetic ore separation plant, Edison (now Ogdensburg), New Jersey, c. 1895. ... By 1901 Edison had spent $2.9 million—equal to $78 million in 2014—making electromagnetic ore separation practical. At the end of the nineteenth century, he lived through an experience that the entrepreneurs extracting crude oil from Alberta's tar sands and ...
The ore passing from the furnace is cooled and fed to a second Wetherill-Rowand separator which removes the chalcopyrite as a magnetic product; the concentrate from this machine carries from 12 to 20 per cent. copper, and the tailing from 0.2 to 0.5 per cent. copper, varying with the quality of the ore and the amount put through.
Magnetic separation is used to enrich iron ore samples that demonstrate either para- or ferromagnetic behavior (Flippov et al. 2014). Magnetic separation can be performed on wet or dry material, with wet being a slurry (Flippov et al. 2014). Magnetic separators are broken down into two categories: high and low intensity (Flippov et al. 2014). Low
Copper oxide ore has a complex composition, and a low recovery rate is often achieved via the traditional sorting method.
