Guar (Cyamopsis tetragonoloba L.): A Potential Candidate for …
Excessive feldspar mining is becoming an alarming issue due to the untreated mine spoil. For the success in the remediation of mine spoil, selection of plant species is an important factor. Therefore being a nitrogen fixer, legumes can be an alternative and are needed to be broadcasted for the rehabilitation of mined lands.
Extraction of potassium from K-feldspar through potassium
Introduction N, P, Ca, Mg and K are important macronutrients for plants (Prajapati and Modi, 2012). Out of these macronutrients, K is limited due to lesser availability in the soluble form in the soil (Prajapati and Modi, 2012, Maathuis, 2009). ... sequestering organic carbon and waste management of K-feldspar, mica, and other such mining ...

Potassium salts (KCl) have over 60 percent K 2 O and are mined from ore that contains 20 to 30 percent K 2 O. Potassium silicates, such as potassium feldspar, contain 8 to 16 percent K 2 O but have low solubility, Van Straaten said. (The alternative hydrosyenite developed at MIT contains about 12 percent K 2 O.) "The challenge is to …
