I fur trap and hunt for food, thus I kill a lot of animals. I

Dilution by magnetic filtering.
Although you'll need a looooooooot of blood to make a knife from blood. And the extraction process will probably take time as well.

About .01% of the body is comprised of iron. So assuming you find a 150 pound man, you'd get around 6-7 grams of iron. so you could make a really small dagger. Like really really small. As for the actual amount of iron you need to make a knife of any particular dimension, i am not sure, but you will surely need more than 7 grams

Can it be done /diy/, or do I need expensive science equipment?

>>7974149
I'm asking how to extract iron and you literally could not or chose not to comprehend my question. I already know how much iron I need to make a sword and on average how much iron I could get out of a deer or bear.

That's dumb. You're dumb.

I would like to make a 500kg iron hammer, only the most carbonated iron please

You have greater problems than getting iron for a knife, Anon.

>>7974129
Why not just make a bone handle

Well, apparently there are 4 atoms of iron per hemoglobin, and the mass of hemoglobin per liter of human male blood is approximately 160g/L. Of this mass, the percent mass of iron is about 0.340 %, or a ration of 0.00340. So the mass of iron in blood is about 0.554g/L. Assuming a lossless extraction process, to create a knife of 500g from blood will take approximately 902.5 LITERS of blood. Assuming that a deer has 5L of blood, it will take 180.5 deer in completely lossless processes to obtain enough iron.

I like animals, please do not kill that many.

This.

The actual amount of iron in blood is too low to make it a worthwhile extraction. Also, the iron is not metallic but atomic and bound in protein globins. There are ways to lyse the cells though and at least free the Iron into solution -- like plenty of hemolytic bacteria do.

I'm also thinking that maybe an acid/heat treatment to denature the proteins, then some sort of phase separation might work with a reagent to bind Iron and mobilize it to an organic phase. But of course this would be purely for the chemistry. The yield would be excruciatingly low.

>>7976188
Deers have a lot more than 5 litres in them.

>>7976517
Assuming 9% blood by weight. Assume a buck of 65kg. 9% of 65 kg is 5.85kg. A conversion factor of 1060kg/m^3 is the density of blood. 0.005518868M^3 of blood. This is then multiplied by 10^6 to get cubic centimeters. There are 1000cm^3 per liter. This yields 5.5L of blood in a buck. Repeat the calculations for a doe and I bet you will be close to an average of 5.25L.

>How do I extract iron from their blood
Kill a dozen of your enemies, burn them to ashes, carefully pour their ashes into a crucible, heat that crucible to very hot, and collect the iron at the bottom?

lol that guy is overweight with bad complexion

high blood pressure and clogged arteries

probably dick doesnt get hard so he lives innawoods to pretend hes a man

should be vegan

Jesus. That's about as many deer as I've killed in my entire life time of hunting.

OP's iron will oxidize before he has enough.
