A most recent addition eddy current separators feature is an eccentric magnetic rotor for separation of nonferrous metals at MRFs. The unit is designed with an eccentrically mounted magnetic rotor within the nonconductive shell. This eccentric rotor concentrates its eddy current forces into a separation zone at the end of the belt. By focusing its field, this design protects the equipment from ferrous material in the flow. The eccentric rotor design reduces long-term wear caused by ferrous build-up.
Another pepper mill that performed well in our test was the Fletcher's Mill model. It has a sharp grinding mechanism and is one of the prettiest models we tested, made of sleek cherry wood with a nice hourglass shape. The pepper mill does require you to remove the metal piece on top when refilling, but its opening is much larger than Peugeot's, making it much easier to pour peppercorns in without spillage. However, the major dock against this model is that its adjustable grind settings can only be changed via the metal piece on the top. It's imprecise and difficult to know what grind you're getting. Still, it's pretty, functional, and made of quality materials. It's also made in America, using sustainable wood practices.
Hematite can also be ground to a fine powder that when mixed with water will make a liquid with a very high specific gravity. These liquids are used in the "float-sink" processing of coal and other mineral material. The crushed coal, which has a very low specific gravity, is placed on the heavy liquid and the light clean coal floats, while high-specific-gravity impurities such as pyrite sink.
It should be noted that 9 per cent, represents non-magnetic iron, or that about 75 per cent, of the iron occurring in this tailings sample is non-magnetic and cannot be charged to the inefficiency of the separation.
Martian "Blueberries": In 2004, NASA's Mars Exploration Rover Opportunity discovered that soil near its landing site contained millions of tiny spheres that researchers nicknamed "blueberries." Upon analysis, they were determined to be composed of iron oxide, mostly in the form of hematite. The iron content of Martian rocks and soil contribute to its red appearance from Earth and helped it earn the name "The Red Planet." Image by NASA.

The concentration of low-grade magnetic iron ores, separating the magnetite crystals from the gangue by the use of magnets, is a field of work in which the lessons taught by the development of the porphyry coppers can be studied to advantage. Large-scale operations, and the liberal expenditure of enough money at the start to insure the most economical operations, are the means of securing the desired results.
The following reports show results of samples tested to determine treatment required and quality of concentrates that could be expected. These tests were run on a regular mill size separator and the results could be duplicated in actual practice. The separate determinations of iron as magnetite, and total iron, were made so that the difference between the two would show the amount of iron combined as silicates in hornblende and other gangue minerals.
The saturation point is the flux density at which the material can not contain any more magnetic flux. Steel saturates around 22,000 Gauss, while MuMetal saturates at about 8,000 Gauss.
Traditional grain mills are usually made from cast iron, which is highly durable and holds up well to heavy use. Some are made of aluminum, which is not quite as durable but offers a lightweight design. Some grain mills feature elegant wooden cases that look very attractive sitting on your counter but aren’t as durable as cast iron or aluminum. Many electric models feature a plastic case or housing. They are fairly durable and easy to clean, though the housings can sometimes crack.

The major difference between the fluidized-bed opposed-jet mill and conventional jet mills is that comminution takes place exclusively in the fluidized bed as a result of the particles impacting against each other, and is thus largely free from wear, because the particles never impact at high speed against the machine wall. The only wear-prone component in the mill is the classifying wheel, which can be protected by selection of a suitable construction material. Monobloc classifying wheels made of aluminum oxide and silicon carbide have proven themselves in operation for even the hardest and most abrasive products.
The number of so-called magnetic separators for which patents have been taken out has been so large that it would be a waste of time even to try to enumerate, them. Many of them were mere toys and a number were mechanical monstrosities. The belt and drum machines of the Ball and Norton patent have accounted for 90 per cent, of magnetic concentration by the dry process; while the wet magnetic process has been entirely monopolized in this country by the Grondal-type machine. There are no patents today controlling magnetic separation, and there is no longer any chance for any now or startling discoveries in this line.
