· "Antimony was a good test vehicle for the idea, but we could imagine doing something similar for much more common metals," Sadoway says. And while this demonstration used an ore that is a sulfide (metal combined with sulfur), "we see no reason why this approach couldn't be generalized to oxide feedstocks," which represent the other major egory of metal ores. Such a process would ...

الحصول على السعر· Re: Does blood float or sink in salt water? Say at a water temperature of 12 C. Whether a fluid floats or sinks in another fluid would depend on their specific gravities. If the specific gravity of blood were greater than that of salt water, the blood would sink; otherwise it would float. Pure water, by definition, has a specific gravity of 1.
