Abstract

The invention provides an iron removal process for low-quality potassium feldspar and relates to the technical field of mineral separation processes. The iron removal process for low-quality potassiumfeldspar comprises the following steps: (1) preparing potassium feldspar sand powder; (2) preparing potassium feldspar fine powder; (3) performing acid leaching to remove iron; (4) rinsing the potassium feldspar; (5) recovering the pickling solution; and (6) drying. The problem that the low-quality potassium feldspar is high in iron content is effectively solved. The potassium feldspar powder with high quality and high purity is prepared by virtue of a series of treatments. The purification process is capable of meeting the requirements on high-whiteness potassium feldspar sand powder in theindustries such as domestic glass, ceramics, enamel and the like, and also has the characteristics of being high in production efficiency, low in energy consumption, harmless, pollution-free and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of beneficiation process, in particular to a process for removing iron from low-quality potassium feldspar. 【Background technique】 [0002] Feldspar is an aluminosilicate mineral containing calcium, sodium, and potassium. There are many kinds of it, such as potassium feldspar, albite, anorthite, and sanidine. They all have glass luster and come in a variety of colors, including colorless, white, yellow, pink, green, gray, black, etc. Some are transparent, some are translucent. Feldspar itself should be colorless and transparent. The reason why it is colored or not completely transparent is because it contains other impurities. Some are lumpy, some are plate-like, and some are columnar or needle-like. Among them, potassium feldspar is an important industrial raw material with a wide range of uses, mainly used in ceramics, glass, enamel and other industries. However, natural potassium feldspar ores usual...
