The first description of a process for isolating antimony is in the 1540 book De la pirotechnia by Vannoccio Biringuccio. Bismuth was described by Agricola in De Natura Fossilium (c. 1546); it had been confused in early instances with tin and lead because of its resemblance to those parts. In humans, some metals are both important vitamins (typically iron, cobalt, and zinc), or comparatively innocent (similar to ruthenium, silver, and indium), however may be poisonous in bigger quantities or certain forms.
Iron, a heavy metal, could also be the most typical because it accounts for 90% of all refined metals; aluminum, a light-weight metal, is the next most commonly refined metal. Pure iron could be the least expensive metallic component of all at value of about US$zero.07 per gram. Its ores are widespread; it’s easy to refine; and the expertise involved has been developed over lots of of years.
