METHOD OF MANUFACTURING BASALT POWDER, BASALT FIBERS AND OTHER SHAPED PRODUCTS

摘要

The present invention relates to the method of manufacturing basalt powder, basalt fibers and other shaped products, comprising grinding the raw material of basalt and optionally melting the basalt by heating it to a temperature in the range of 1450°C to 1550°C, characterized in that, the raw material of basalt is crushed to obtain a particle size of less than 5 mm, preferably in the range of from 1 to 3 mm, then, the thus obtained powdery raw material is combined with water in a ratio of 5 to 50 liters of water per 100 g of basalt, and obtained suspension is homogenized, processed through further fragmentation and purification in the reaction chamber equipped with electric pulse generator, wherein the water and basalt powder suspension is simultaneously electrolyzed within the same chamber, equipped with at least one carbon based electrode, on which retain basalt impurities, then solid particles of basalt are separated from the water and dried under anaerobic conditions, and then optionally melted in a temperature in the range of 1450°C to 1550°C and optionally basalt fibers, or other shaped products are prepared.
