Reagents for the removal of iron minerals include a combination such as hydrofluoric acid for a pH of 5, sodium resinate and a frother. The conditioned pulp is then diluted to a 20-25% solids for flotation. Complete removal of iron minerals along with some remaining feldspar is accomplished in a froth product which is small and is discarded.
It is a soft, earthy, usually white, mineral (dioctahedral phyllosilicate clay), produced by the chemical weathering of aluminium silicate minerals like feldspar. In many parts of the world it is colored pink-orange-red by iron oxide, giving it a distinct rust hue. Lighter concentrations yield white, yellow, or .

Request PDF on ResearchGate | Extraction of potassium from K-feldspar via the CaCl2 calcination route | The extraction of potassium from K-feldspar via a calcium chloride calcination route was ...
The extraction of potassium from K-feldspar via a calcium chloride calcination route was studied with a focus on the effects of the calcination atmosphere, calcination temperature and time, mass ratio of CaCl 2 to K-feldspar ore and particle size of the K-feldspar ore. The results demonstrated that a competing high-temperature hydrolysis reaction of calcium chloride with moisture in a damp ...
Calcination, the heating of solids to a high temperature for the purpose of removing volatile substances, oxidizing a portion of mass, or rendering them friable. Calcination, therefore, is sometimes considered a process of purification. A typical example is the manufacture of lime from limestone.

Apr 22, 2015· Abstract. Based on the academic thought of carbon capture and utilization, a novel process to integrate the potassium extraction from the insoluble potassium feldspar, industrial waste utilization, and the subsequent CO 2 fixation using the resultant potassium-depleted residue was proposed in our previous studies. The potassium-depleted residue comprises several Ca-bearing .
