Description

technical field

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

[0002] Coal gangue is an industrial solid waste produced during coal production, and it is one of the most discharged industrial solid wastes 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 from it, producing build...
