The Science and Technology Daily reporter learned from the Natural Resources Department of Heilongjiang Province on February 26 that the province had discovered a super-large graphite deposit in Xigou, Shuangyashan City. After evaluation, the potential economic value of the mine can reach more than 100 billion yuan. This is a major breakthrough in domestic geological prospecting.
Heilongjiang Province has a vast territory and rich mineral resources. In order to transform the advantages of mineral resources into economic advantages as soon as possible, in 2015, the Heilongjiang provincial government made an important deployment of three years of special operations for geological exploration. As one of the main force of geological prospecting in the province, Heilongjiang Nonferrous Metals Exploration Bureau promotes the “three-year geological survey special projectâ€. After four years of arduous exploration, the Qilong 1 team of the Heilongjiang Nonferrous Metals Geological Exploration Bureau discovered super-large graphite deposits in Xigou, Shuangyashan City.
The genetic type of the deposit is a sedimentary metamorphic graphite deposit. The type of ore is mainly graphite gneiss. It belongs to large scale slab graphite. A total of 62 crystalline graphite ore bodies were found. It was submitted to the industrial mine by the Heilongjiang Provincial Department of Natural Resources. The volume of (333)+(334) graphite ore is 3,351,911,000 tons, the mineral content is 2,337.61 million tons, and the average grade is 6.97%. Among them, (333) accounted for 95.22% of the total resources, and the total stripping ratio was 1.69:1.
Graphite belongs to the country's strategic mineral resources and is an important raw material for the production of diamond and graphene. Diamond and graphene are also known as “revolutionary†because of their extremely broad application prospects in energy, biotechnology, aerospace and other fields. The material "the king of materials in the 21st century." Shuangyashan Xigou Graphite Mine is a high-quality graphite resource with large reserves, easy exploitation and low cost.
