Rushan Jinhua Mining Co., Ltd. was founded in 1971, and now has four gold enterprises and six non-gold enterprises, namely Daye Gold Mine, Dongling Gold Mine, Baishi Gold Mine and Hujiakou Smelter. The existing gold reserves of gold mines are 50 tons, including 28 tons in Tangjiagou Mining Area, Dongling Mining Area and Baishi Mining Area, and 22 tons in Daye Mining Area.
Tangjiagou mining area is located in the Mouru fault zone, which has a good metallogenic prospect. With the progress of prospecting engineering, the gold reserves will have a breakthrough growth. Tangjiagou mining area has carried out five-year reconstruction and expansion project, with an investment of 600 million yuan to drive 130,000 meters of standard roadway and five new shafts, realizing automatic lifting project, remote automatic pumping project and fire fighting project, and all the shoveling projects have realized mechanization and electrification. Two standardized disaster avoidance chambers were newly built, and 5G networks were laid underground, and two sets of communication network engineering and personnel positioning engineering were realized, which made the six underground positioning systems reach the advanced level of domestic mines. Mine management has reached the first-class level in the industry.
The company has two concentrator, of which Daye concentrator is 5000 tons/day and Tangjiagou concentrator is 3000 tons/day. The two concentrator can handle 3 million tons of ore and produce 3 tons of gold annually. The production capacity of the gold smelter is 300 tons/day, with an annual processing capacity of 100,000 tons of concentrate powder, 6 tons of finished gold, 15 tons of brass and 5 tons of silver. Now it has 1200 employees, including 13 senior engineers, 15 mining engineers, 12 geological engineers and 85 other engineers and technicians. The company's total fixed assets are 2 billion yuan.
With the Ministry of Trade, it imports 1.5 million tons of iron ore and copper ore annually, and the foundry produces pig iron and cast steel materials.
The company has five non-gold branches for comprehensive utilization of tailings resources: Weihai Chengye Co., Ltd., which mainly extracts sericite powder from tailings, with an annual output of 150,000 tons; Rushan New Building Materials Company mainly uses tailings to produce 500,000 cubic meters of aerated bricks; Two building materials stone factories, using waste stones produced underground, process and produce 500,000 square meters of various stones; The sand factory uses tailings and gravel fine materials to wash sand, with an annual output of 2 million tons, and uses tailings to fill 200,000 square meters underground every year; The company's annual output value is 5 billion yuan, including 2 billion yuan for gold enterprises, 3 billion yuan for non-gold enterprises and 350 million yuan for annual taxes. Through the comprehensive utilization of the above resources, waste-free mines and green construction mines will be gradually realized, which has achieved comprehensive utilization of resources and achieved good economic and social benefits.
