Does anyone know if it really is iron, and if so, what form might it be in and if recovery for smelting is a viable option
How it stains cement when a fair amount of weathering takes place
That was my first thought too, get a Harbor Freight magnet on a stick, and walk around with a bucket collecting whatever comes up. Roast some, drop it in a crucible with a little glass, and charcoal, and see if you can reduce some metal out of it.
Fools gold is iron pyrites. Iron is a very common element planet wide. Those rocks look rusty. Get busy with a magnet.
When you work gold down in a sluice box or pan you will get heavies that are both magnetic and non-magnetic. So you would use a magnet to seperate it out as mentioned above. I used to do a lot of prospecting and saved both after seperating. But it was several years later that I got into knifemaking and trying to smelt. By that time I was not able to find them. All that work and then to not have it when I need it.
But I also found out the local hematite does not have a high iron content so its not the best to smelt. You can look at it under a cheapo microscope and see how much hash and trash is bound up with the iron. I have a digital microscope and if you want you can send me a pinch and I can look at it and email you the pics.
Gold and iron ore are the standout commodities so far this year, but the performance of their respective miners are far more divergent - and weighted in favour of the precious metal.
LAUNCESTON, Australia, June 15 Reuters - Gold and iron ore are the standout commodities so far this year, but the performance of their respective miners are far more divergent - and weighted in favour of the precious metal.
Spot gold closed at 1,729.67 an ounce on June 12, up 14 since the end of last year. Meanwhile benchmark 62 iron ore for delivery to China MT-IO-QIN62ARG, as assessed by commodity price reporting agency Argus, was at 104.45 a tonne, a gain of 14.6.
If the year-to-date performances are very similar, the underlying drivers of iron ore and gold are quite different.
The steel-making ingredient is benefiting from Chinas economic stimulus push as it recovers from the novel coronavirus, coupled with number two exporter Brazils struggles with the same disease.
While there is also a coronavirus element to golds rise, what investors are buying into is the belief that the weak global economy and expected extended recovery period mean low interest rates and heightened volatility of other asset classes.
Given that iron ore has rallied to a 10-month high and has both bullish stories for both demand and supply, its perhaps surprising that the top miners are generally not sharing the good news.
Shares in Rio Tinto, which derives the bulk of its profits from its iron ore mines in the state of Western Australia, are down 3.7 so far this year in Australian dollars and 4.8 in U.S. dollar terms.
Stock in BHP Group, Australias second-biggest iron ore producer behind Rio, is down 9.6 in U.S. dollars, with some its underperformance versus Rio likely being explained by the companys greater exposure to crude oil and natural gas.
But both Rio and BHP will be huge cash generators with iron ore at its current price, given their cost to produce a tonne of iron ore is around 14-15.
