Shandong Jin Yi mining co., LTD., founded in 2003 on December 19, a registered capital of 115.5 million yuan, formerly known as shandong gold group nearbu mining co., LTD., located in shandong province changyi city, covers an area of 230000 ㎡, is a collection of iron ore underground mining, mineral processing, iron ore, iron essence pink acquisition, the sale in a body's comprehensive mining enterprises.

　　The company has two projects under its jurisdiction: 1 million t/a mining project of Lianhuashan Iron Mine and 1 million t/a mining project of Dongxinzhuang Iron Mine and 2 million t/a ore dressing project, respectively establishing independent mining rights. Proven iron ore resources amount to 64 million tons. Since 2008, the construction period is 3 years, the designed annual processing capacity is 2 million tons, the annual output of iron concentrate is more than 600,000 tons, the total investment is 1.4 billion yuan, the service life is 23 years. The mining design adopts the development mode of vertical shaft zoning, centralized transportation and centralized lifting, and the full tailings filling mining technology. The final product is iron concentrate by two-stage closed-circuit magnetic separation process with high pressure roller grinding. After the completion of the project, it will increase local tax revenue by more than 100 million yuan.

　　Nearbu mining company formerly known as shandong gold group co., LTD., the project construction of a high starting point, high standard, mine in weifang area the largest underground mine enterprises, focus on the construction goal of "creating industry benchmarking enterprise" in the province, vigorously promote energy conservation and emissions reduction and koala mine construction process, and from the beginning of the design pay attention to the "simple, speed, size, efficiency, safety, energy saving, environmental protection" for the construction of the concept throughout the whole project construction. Relying on the advantages of resources, the company pays more attention to the research of mining methods, the transformation of mineral processing process and the investment of safety facilities, which provides a strong technical support for safe production.

　　Adhere to the construction of "green, green, low carbon, koala mine" development purposes, the company increased investment in energy conservation and emissions reduction, low carbon environmental protection projects, has invested nearly one hundred million yuan from Germany, Finland, the United States and other countries the introduction of many sets of advanced technology, high environmental protection, low energy consumption mineral processing equipment, to make in the same industry in the province koala benchmarking enterprises with strong support. In April 2013, the company was approved as the third batch of national green mine pilot units. It has become a modern tailless green mine with fast speed, excellent equipment and high degree of automation in Changyi region.

　　Company at the same time, speed up the development of positive social responsibility, to build first-class "intelligent mine" and "green mine" as the goal, into the premise and foundation of mine digitalization, information management of mine production, occupational health and safety, technical support and logistical support for active perception, such as automatic analysis, rapid processing, intelligent decision-making and scientific command. To cherish resources, scientific development, automatic control, optimization of process, saving energy and reducing consumption, increasing benefit, ecological protection, beautify the environment, dust dust suppression, prevent pollution, recycling, water conservation as a bridge and optimizing the engineering design, earnestly implement the green mine construction index, ultimately achieve safety mining, unmanned mining, efficient, clean the construction of the mine.
