Abstract

The invention provides a method of purification of potash feldspar and soda feldspar ores and relates to the technical field of ore dressing processes. The method of purification of the potash feldspar and soda feldspar ores, provided by the invention, comprises the following steps: (1) preparing potash feldspar and soda feldspar sand powder, (2) preparing potash feldspar and soda feldspar refinedpowder, (3) carrying out acid pickling, (4) flushing potash feldspar and soda feldspar, (5) treating first flushing fluid, (6) treating second washing liquid and (7) carrying out drying. According tothe method, the problem that the ferrum content of the potash feldspar and soda feldspar is high is effectively solved, high-quality and high-purity potash feldspar and soda feldspar powder is obtained through a series of treatments, ore concentrate obtained by the purification process reaches first-grade quality indexes of feldspar products of our country in application to glaze, ceramic blanks,flat glasses and the like, and meanwhile, the method has the characteristics of high production efficiency, low energy consumption, harmlessness, no pollution and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of beneficiation technology, in particular to a method for purifying potassium albite ore. 【Background technique】 [0002] Feldspar is a group of minerals composed of aluminum silicates of potassium, sodium, calcium and barium. It is the most common ore in the earth's crust, with a proportion of 60%. It can appear in igneous rocks, metamorphic rocks, and sedimentary rocks. The melting point of feldspar is between 1100-1300 ℃, and it has good chemical stability. It has a melting effect when eutectic with quartz and aluminosilicate. It is often used as an auxiliary agent for making glass and ceramic blank glazes, and can reduce Firing temperature; In addition, the formation of feldspar glass body can also improve the light transmittance of the green body. [0003] Most feldspar deposits can be divided into albite deposits, potassium albite deposits and mixed potassium albite deposits. The feldspar minerals...
