Feldspar containing a certain proportion of quartz is saleable; No. 1 contains less than 5% of quartz, No. 2 up to 15% or 20%, and No. 3, still higher, but not over 30%. Microcline and orthoclase are the varieties of feldspar commonly mined. Users prefer a potash feldspar, but the soda feldspar.
Gaofu potash feldspar dewatering screen has less investment and energy consumption than filter press, which is convenient in operation and has a better effect than spiral classifier. It is the first choice of potash feldspar mineral separation and dehydration. Potash feldspar need to be graded after milling.

announced 90% potassium recovery from 8% K2O bearing feldspar below 70 microns with the addition of 1:8 CaCl2 to potassium feldspar at a roasting temperature of 900 C, for an 8-hour duration [11]. Jena et al. reached 92.8% potassium recovery from 10.89% K2O bearing feldspar with the addition
The sulfides, mica, and feldspar were floated in turn and produced a potash feldspar containing the following, in percent: 9.9 K2O, 0.73 Na2O, 0.97 CaO, 24.6 Al2O3, and 61.0 SiO2. Sample NMA. Petrographic analysis of sample NMA showed that dark minerals were locked with feldspar and quartz grains. A potash feldspar concentrate

The Bureau of Mines used several laboratory batch flotation schemes combined with magnetic separation to investigate the feasibility of recovering potash feldspar and glass sands from molybdenite tailings. Four molybdenite tailings of prospective tailings were used as test samples. Feldspar ...
The other one may be an indirect route in which muscovite at high temperature along with SiO 2, forms K-feldspar that further reacts with CaCl 2 to give the sylvite phases. It is also noticed that a further increase in roasting temperature to 1100 °C leads to a decrease in potash recovery with the possible reasons being the formation of water ...

The tailing from the petalite circuit (i.e. recovery stage) can be used for recovery of soda and potash feldspar which are also valuable market commodities. Adding brine in the petalite recovery step provides a high degree of separation between petalite and feldspar minerals such as .
In the case of acid medium, same concentration of potash can be extracted along with the dissolution of Ca as CaCl2. While in the case of MgCl2 as the flux, it is noticed that only 35% of K can be recovered. The results indicate that maximum recovery of potash is achieved when the feldspar to flux ratio (Feldspar: CaCl2) is 1:8 to1:10.
Feldspar ore is the main source of feldspar mineral concentrate or purified feldspar used in the manufacture of various grades of glass and ceramics including high-end ceramics and electronic-grade glass fibers. The glass and ceramic industries, in particular, are major consumers of feldspar, accounting for 95% of total consumption.
