Recently, the 103rd team of Liaoning Nonferrous Metals Bureau has made significant progress in the prospecting of crystalline graphite in Liaoyang City, Liaoning Province. Through surface trenching and deep drilling engineering control, a total of 1,214,560 tons of graphite (331+332+333) ore and a fixed carbon mineral amount of 6,714,800 tons were discovered, which is the largest crystalline graphite with proven ore resources in Liaoning Province. mine.

It is understood that the project began field geological work on April 15, 2016, mainly carrying out 1:2000 measured geological section, 1:5000 geological survey, 1:2000 geological survey, trench exploration, drilling, etc. A total of 5 million yuan. 31 graphite ore bodies were found in the carbonaceous slate of the Miaodonggou-Dongshan Dongshan Gaojiatun Formation. Through the exploration of the ground surface and the deep control of the drilling project, a total of 12,145,600 tons of graphite (331+332+333) ore was discovered. Tons, the fixed carbon minerals amounted to 674.18 million tons, and the fixed carbon average grade was 5.55%. Among them, 331 types of graphite ore were 2.9013 million tons, fixed carbon minerals were 236,600 tons, fixed carbon average grade was 8.15%; 332 types of graphite ore were 48.477 million tons, fixed carbon minerals were 2,580,600 tons, and fixed carbon average grade was 5.32%; The amount of graphite-like ore is 7007.77 million tons, the fixed carbon mineral content is 3.924 million tons, and the average fixed carbon grade is 5.60%.

The graphite ore-bearing horizon is the second member of the Dashiqiao Formation. The surrounding rock of the ore body is composed of crystalline graphite granulite and crystalline graphite carbonaceous slate. The graphite ore body is controlled by the inter-layer fault structure. The active part of the structure is better in graphite mineralization, and the ore body changes stably, extending more than 3,000 meters. The scaly crystal graphite is visible to the naked eye. After testing and ore dressing test, it is crystalline graphite, scale-like, ore easy to be selected, and the recovery rate of ore dressing experiment can reach more than 90%.

Graphite is an important strategic resource in China. It is widely used in modern high-tech industries such as metallurgical chemical industry, machinery and electronics, national defense military industry, etc. The national “13th Five-Year” development plan lists graphite materials as the key focus of new material development strategy. “National Mineral Resources Planning” Graphite is also included in the strategic minerals catalog.
