EXTRACTION OF POTASSIUM FROM FELDSPAR AND . able in feldspar and leucite, so the extraction of the desired potassium compounds would be easier. The roasting process of feldspar and leu-cite is shown in Figure 3, while the products of roasting are shown in Figure 4. Figure 4 shows that the feldspar samples were still in .
Zhang et al. claimed that when feldspar:CaCl 2:NaCl roasted together at a ratio of 1.8:1.1:0.6 at 800 °C for 1 hour, the potassium extraction reached 95.5%, starting from 14.81% K 2 O bearing feldspar with a grain size under 70 microns.
Feldspar had been discarded in the process of mining mica until William Dibbell sent a premium quality product to the Ohio company Golding and Sons around 1910. [22] In earth sciences and archaeology, feldspars are used for potassium-argon dating, argon-argon dating, and luminescence dating .

Feldspar extraction processing plant 1. Crushing and grinding. The crushing and grinding of feldspar are not only to meet the grain size requirement of the final product, but also to meet the need of the impurity removal process. The coarse crushing of feldspar mostly adopts jaw …
In this paper, the process of extracting potassium from K-feldspar ore based on low temperature molten salt method was studied systematically. The factors that affect the extraction of potassium were investigated detailedly, and they were mass ratio of NaNO 3 /K-feldspar, NaOH/K-feldspar and H 2 O/K-feldspar, particle size of K-feldspar ore ...
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 ...

before the dissolution process, different parameters such as particle size, roasting temperature, and duration, as well as the feldspar/CaCl2 ratio, were tested. Under the optimum conditions (i.e., 106 microns, 850 Co, 60 minutes, 1:1.5 feldspar:CaCl2), 99% of the potassium was successfully extracted from the ore feed.
The washing process is suitable for feldspar produced from weathered granite or feldspar placer, which mainly to remove impurities such as clay, fine mud and mica. On the one hand, it can reduce the content of Fe2O3 in feldspar ore, on the other hand, it can increase the content of potassium and sodium in feldspar …
A froth flotation process is used for most feldspar ore beneficiation. Figure 11.27-1 shows a process flow diagram of the flotation process. The ore is crushed by primary and secondary crushers and ground by jaw crushers, cone crushers, and rod mills until it is reduced to less than 841 µm (20 mesh). Then the ore passes to a three-stage, acid ...
