Problems solved by technology

Enterprises generally use open-air stacking to deal with coal gangue. On the one hand, it takes up a lot of land. On the other hand, the harmful substances in coal gangue will pollute the 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 building materials with coal gangue as raw materials, etc., but these technologies...

Embodiment 1

[0032] Example 1: Press figure 1 As shown, the production raw materials and proportions:

[0033] Coal gangue: 100%.

[0034] The preparation method of artificial red agate is:

[0035] (1) Weigh a certain weight of coal gangue;

[0036] (2) Crushing and grinding massive coal gangue raw materials;

[0037] (3) Put the coal gangue that has been ground into powder into a heat treatment furnace for heating to remove moisture and organic matter in the gangue. The feature is: put the coal gangue powder into a crucible, put it into the heat treatment furnace at room temperature, and heat up with the furnace; The temperature is 600°C, heat preservation for 10 hours; then cool to room temperature;

[0038] (4) Take out the cooled coal gangue powder, weigh it, and put it into a heat-resistant glass container;

[0039] (5) Prepare 10% hydrochloric acid aqueous solution;

[0040] (6) Use a measuring cup to measure the hydrochloric acid aqueous solution, the amount to be measured is...

Abstract

The invention belongs to the field of handicraft production, in particular to an artificial onyx made from coal gangue and a manufacturing method thereof. It is characterized in that the raw material of the present invention is coal gangue, and the preparation steps are: weighing, crushing, grinding, heating to remove water and organic matter, preparing hydrochloric acid aqueous solution, measuring hydrochloric acid aqueous solution, mixing coal gangue and hydrochloric acid solution, and heating to remove metal oxides , filtering, drying, weighing ferric oxide powder, smelting, pouring, carving, grinding, polishing. The artificial red agate prepared according to the invention is ruddy in color, fine and tough in texture, moist and soft in luster, and has good mechanical properties, can be used in the field of handicrafts, and has broad application prospects. The invention uses coal gangue as production raw material to produce products with high added value, realizes the high value-added utilization of coal gangue, and opens up a new way for its comprehensive utilization.

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...
