Problems solved by technology

However, natural potassium feldspar ores usually contain mica, tourmaline, quartz, weak magnetic iron minerals, etc., and some weathered ores also contain kaolin. The complex composition of these impurities restricts the application of potassium feldspar in many industrial fields. The reduction of feldspar mines, the decline in quality, and the continuous improvement of product quality requirements. Therefore, it is necessary to select useful minerals through physical and chemical treatment, remove impurities, and reduce the content of harmful elements to achieve technical indicators for industrial use.

Abstract

The invention provides a mineral processing technology of potash feldspar, and relates to the technical field of the mineral processing technology. The mineral processing technology of the potash feldspar comprises the following steps of (1) crushing, (2) ore grinding, (3) desliming, (4) magnetic separation, (5) flotation, (6) acid pickling of potash feldspar fine powder, (7) flushing washing of the potash feldspar and (8) drying. According to the mineral processing technology of the potash feldspar, the final fine powder is obtained from raw ores, the recovery rate reaches more than 90%, thetechnology procedure is simple, the operation is convenient, production water generated in the technology is recycled, the water consumption is saved, and environmental resources are protected.

Description

【Technical field】 [0001] The invention relates to the technical field of mineral processing technology, in particular to a mineral processing technology of 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 usually...
