      That's because magnetite has a much higher yield than hematite, and they ran a large amount of the black sand thru it between feedings.
      It boggles my mind how many hobbyists out there get even those most basic details right ... not tall enough, insufficient airflow, insufficient fuel, insufficient ore, etc. There are so many vids out there with the resulting bloom being tiny, uselessly impure and overfull of trapped slag, etc. It was refreshing to see someone do such a relatively good job.

Done carefully this results in useful material. If you ever see old time iron objects that look like they have a faint wood grain it's the result of that purification folding process.

    I've been trying to make my own iron on and off (mostly off) for a little over a year now, most of that time spent gathering ore. A few things I tried to smelt it didn't work, but yesterday I had a very minor success using my diy gas forge as a bloom furnace. Most of the magnetite sand didn't smelt at all, but some worked out well and coalesced into a couple small melty looking pieces.

Thanks :) I figure from observing scaling from impact working any mass manufactured iron/steel, there will be losses of mass at any process of compaction shaping. Carbon reduction, impurities etc. Thinking of it, it does sound much like the Bessimer... On mere ish assumption; How much stronger could a traditional poured steel cast anvil become, compared to one well forged in iron ?

    • @jakobhalskov
      @jakobhalskov  Рік тому

      A comment on the Bessimer process; the iron in a blommery dose not really melt. Though planning on doing a video on hearth fining iron, to reduce phosphorus and slag, maybe make some steel. With out promising anything.
      About the strength, using tensile strength as a proxy for strength/toughness/quality. As from the 2 articles I can find on strength of bloom/wrought iron. Bloom/wrought iron have a tensile strenght of 200-300 MPa. The samples was probably not heat treated, though the low C content is not allowing for much hardening. In comparison to 4140 alloy (common tool steel) have a tensile strength of 900-1500 MPa. after heat treatment. Not in any way a one to one comparison but might give a ballpark feeling of the difference, might be completely wrong.
      One "common" failure of old forged anvils is the horn and heel gets knocked off with sufficient abuse, because the anvil is forge welded together from multiple pieces. But there are also many anvils that have not broken in that way.

      @@phillipsusi1791 They did that with pig/cast iron, but cast iron has a lot of carbon in it which lowers the melting temperature (to about 1100-1200'C). The excess carbon also makes it more brittle and less malleable, and impossible to do forge work with. Wrought iron and steel has much less carbon in it, so the melting temperature is higher (above 1400'C), too high for the simple charcoal fueled furnaces of antiquity and middle-ages to melt completely. Since smiths couldn't reliably get the iron to melt, forging it to expel slag and consolidate the iron/steel was the next best thing.
      Note, there was also another process in which iron ore was first smelted and processed into cast iron to remove the slag, then the cast iron was remelted over and over again in a finery forge to burn off excess carbon and turn the cast iron into wrought iron. Later on, they expanded the process with the puddling furnace, where a pool of molten cast iron was stirred with iron rods to help carbon burn off. As carbon was reduced and the melting temperature of the iron increased, the solidifying iron stuck onto the rods and formed balls of refined wrought iron. This "puddled" wrought iron was a lot purer and had different properties to the old bloomery type wrought iron.

I'll give it a try next time im at that beach. With the concentrated black sand you need about 4 to 5 times as much sand than iron you expect to extract.

      I'll say it could be done with out the magnet, especially if the sand was collected more carefully, the bog ore is definitely possible to do wit out a magnet if you know where to find decent quality ore.
      The higher amount of silica sand and other non-ferrous minerals in the ore would most likely change the slag chemistry, for the better or worse i cant say. But the yield would be significant less. But how the furnace is operated also have a large impact on the quality.
      Sorting the ore with a magnet, just ensured that we would get iron.

      We did not pan any of the sand for gold, but don't think the conditions at the beach would concentrate gold in any significant amount. At 0:48 you can see the "gems", the brown is most likely garnets, green olive and clear and pink is quarts, but they are sub mm in size; regards Sebastian

    Magnetite is thought to be found only as large crystals, but those are extremely rare. Instead magnetite is found as banded iron formations or in iron sand. In igneous rocks the grains of magnetite are very scarce and minuscule but are concentrated into sand due to weathering.

      Any strong magnet will do; it is just a matter of how much you can pick up at a time. It helps to have something between the magnet and the sand to be able to separate it. We were using a magnet from a medium large generator.
