David Ciceri is using microfluidic techniques to study how potassium leaches from feldspar under exposure to acidic solutions. Ciceri is in the process of writing a review article, which will include a historical perspective, of the potash problem. (See related article.) "We work with a rock which contains 15 percent potash," Allanore says.

Notes. Theoretically speaking, the term 'feldspar' refers to a family of minerals with a specific crystalline presence. However actual feldspar powders are made from crushed crystalline rock containing a mixture of aluminum silicates of sodium and potassium (with minor amounts of lithium or calcium). They normally contain 10-15% alkali (K 2 O, Na 2 …
