Iron
Iron is an essential element for all forms of life and is non-toxic. The average human contains about 4 grams of iron. A lot of this is in haemoglobin, in the blood. Haemoglobin carries oxygen from our lungs to the cells, where it is needed for tissue respiration. Humans need 10–18 milligrams of iron each day.
Rubidium
In 2019, prices of pure Rubidium were at around 12000 $/kg. Rubidium is obtained as a minor byproduct of the processing of lepidolite and pollucite. These ores are found, often together, in just a few zoned pegmatites around the world and are mined on a small scale by selective methods.
