K-feldspar is a member of the feldspar mineral family,the chemical formula is KAlSi3O8.The main components of k-feldspar include potassium, aluminum, silicon, and oxygen, and may contain small amounts of sodium or calcium. Potassium feldspar is one of the most widely distributed minerals in the Earth's crust, particularly common in granite and other igneous rocks. In addition, it is also an important component of sedimentary rocks such as sandstone.

      From a color perspective, k-feldspar generally has white, flesh red, light yellow, gray, etc., depending on the content of impurities inside.From the perspective of color, it presents a glass or pearl luster.In terms of hardness, its hardness is about 6 to 6.5.Of particular note is that potassium feldspar exhibits significant birefringence, which is an important characteristic for identifying this mineral.

       K-feldspar is generally divided into "red k-feldspar" and "white k-feldspar".For "red k-feldspar",the use of a color sorter can effectively distinguish it from other types of potassium feldspar based on color differences,but for "white k-feldspar",it is not feasible.At this moment, the groundbreaking product launched by Hefei Mingde Optoelectronics Company, the AI ore sorting machine, came in handy.

For k-feldspar such as white silicon and white k-feldspar, which may have subtle differences in texture, shape, or other characteristics but do not differ significantly in color, artificial intelligence sorting machines can provide higher accuracy and efficiency. By training neural network models, AI systems can learn to recognize features that are difficult to detect with the naked eye, thereby achieving more precise classification of minerals.
