Artificial jade based on gangue and manufacturing method thereof

Abstract

The invention belongs to the field of handicraft production and particularly provides a method for producing artificial jade from gangue. The artificial jade is characterized by being prepared from all or part of the following raw materials: gangue, quartz powder, alumina or aluminium hydroxide, zinc oxide, sodium carbonate, magnesium oxide, borax, sodium silicate, calcium oxide or calcium carbonate, titanium dioxide, potassium carbonate, talcum powder, manganese dioxide, copper oxide and iron trioxide. The method comprises the following preparation steps: (1) weighing; (2) smashing and grinding; (3) mixing and stirring; (4) smelting; and (5) carving, abrading and polishing. The artificial jade prepared by the method has delicate and tough texture, mild and soft luster and good mechanical property, can be used in such fields as jewelry, handicrafts and the like, and has broad application prospects. By producing the product with high added value from gangue used as the raw material, the invention realizes the high added value utilization of the gangue, thereby opening up a new way for the comprehensive utilization of industrial solid wastes.

Description

technical field

[0001] The invention belongs to the field of handicraft production, in particular to artificial jade produced by coal gangue, an industrial solid waste produced in the coal production process, and a manufacturing method thereof. Background technique

[0002] Coal gangue is industrial solid waste produced during the coal production process. It is one of the most discharged industrial solid waste in my country. At present, it has accumulated more than 3 billion tons, and it is still growing at a rate of 100-200 million tons every year. Enterprises generally use open-air stacking to process coal gangue, which occupies a large amount of land, and on the other hand, harmful substances in coal gangue will pollute groundwater and the surrounding air, thus causing serious harm to the ecological environment.

[0003] Over the years, people have adopted a variety of technologies to comprehensively utilize coal gangue, such as extracting beneficial chemical components f...
