IRON SLAGS ON ARCHAEOLOGICAL SITES: AN INTRODUCTION Lynne Keys HISTORICAL METALLURGY SOCIETY WHAT IS IRON SLAG? There are many different types of iron slag. Some were produced by smelting, others by smithing; some are large, some so tiny they are invisible to the naked eye when in the soil.
Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
The strength of the magnetic field it produces is at any given point proportional to the magnitude of its magnetic moment. In addition, when the magnet is put into an external magnetic field, produced by a different source, it is subject to a torque tending to orient the magnetic moment parallel to the field.
Feb 28, 2019· Flux : It is a compound which is used in metallurgical process to extract gangue(unnecessary elements in ore) material during the extraction of element from ore ...
A process for separating different products from steelmaking slag includes reducing the average particle size of slag from a steelmaking process into fine particle size material, and separating the fine particle size material into at least an iron rich product and a silicate rich product based on the differences between these products in at least one or more properties including magnetic ...
Using the developed process, a magnetic product containing more than 65 wt.% iron was obtained from the magnetic separation under a magnetic field strength of 0.03 T for the waste copper slag reduced by petroleum coke (25 wt.%) at 1250 °C for 1.5 h.
Dec 28, 2010· The copper slag contained tiny iron inclusions that recorded the strength of the geomagnetic field at the time it cooled and solidified. Wired Science reported, "They found that the magnetic field abruptly spiked twice during the 180 years they studied, once around 2,990 years ago and once around 2,900 years ago." 3
Slag and fly ash can also be added to control other properties of the final product both the dry and wet processes are very energy intensive the wet process however uses more energy than the dry process due to the amount of water that must be evaporated b,Wet Process Of Slag Sand Making.
Does steel block a magnetic field or extend it farther? Those sound like opposite results, so why is it sometimes one or the other? It can't be both, right? Maybe it can. On one hand, a string of steel paperclips clearly extends the attraction of a magnet. A paperclip stuck to .
A method of recovering a valuable metal from slag is disclosed. The method includes the steps of: applying a magnetic field whose magnitude is increased in a stepwise fashion to crushed slag to separate a magnetic material from the crushed slag; and introducing a reductant into the separated magnetic material to recover a valuable metal therefrom.

Steel slag iron separation process mainly has the following types: sieve,sieved material gets into the magnetic separator for magnetic separation,those not on the magnetic into the re-election, shaker and the spiral chute separate, the grade can reach above 64%, three times
One of iron's identifying characteristics is that it is strongly magnetic. Exposed to a strong magnetic field, any piece of iron can be magnetized. Scientists believe that the Earth's core is made up of about 90% iron. The magnetic force produced by this iron is what creates the magnetic .
Dec 28, 2010· In contrast, a quickly decaying, rapidly fluctuating magnetic field fits the free decay model and an age for earth of only thousands of years. References. Shaar, R. et al. 2011. Geomagnetic field intensity: How high can it get? How fast can it change? Constraints from Iron Age copper slag. Earth and Planetary Science Letters. 301 (1-2): 297-306.
