Abstract

The invention provides a comprehensive utilization method of granite, and belongs to the technical field of mineral utilization. According to the method, two sections of crushing-screening closed-circuit processes are adopted, and sand manufacturing is achieved by utilizing a vertical impact type crushing machine; black mica is pre-separated by using a strong magnetic roller type magnetic separator; and then black quartz coarse ore, high-potassium feldspar ore and potassium-sodium mixed ore are pre-separated by adopting a color separator, moreover, the separated products are correspondingly subjected to grading and physical method purification, and the obtained final products can meet the requirements of the downstream industry. The whole production process adopts the physical method, no chemical reagents need to be added, moreover, no waste is generated, and green production is really realized. According to the comprehensive utilization method of granite, various valuable components in the granite are fully developed and utilized, the comprehensive utilization rate of resources is improved, the additional value of the products is greatly improved, social benefits and economic benefits are remarkable, and therefore, the method has a wide application prospect in the development and utilization of granite minerals.

Description

technical field

[0001] The invention relates to the technical field of mineral utilization, in particular to a comprehensive utilization method of granite. Background technique

[0002] Granite is the landmark rock of the continent and the foundation of the upper crust of the continent. It can be seen that the reserves of granite are abundant. Due to the lack of effective development and utilization of granite, most of the granite is still in a state of development, even if a small part has been developed and utilized. It is also only selectively cut and polished, and used as the cornerstone of the road, square bricks, or step stones of buildings. These products are not only produced in a harsh environment, but also produce products with low quality and low added value, resulting in serious waste of resources and hidden dangers to the ecological environment.

[0003] Although the composition of granite is complex, it is mainly composed of quartz, orthoclase and microplagioc...
