[last year, 53 indicators of Yuguang gold and lead reached the highest level in history, including 5 indicators of comprehensive energy consumption of crude lead, etc.] recently, Henan Yuguang Gold and lead Group Company held a working meeting in 2022 to commend the advanced units in the work of creating standards in 2021. In 2021, the company's 53 indicators reached an all-time high. Among them, the comprehensive energy consumption of copper and crude lead in tailings, the life of roaster kiln, zinc in lead mud and silver in tailings are the best in the industry.

Recently, Henan Yuguang Gold and lead Group Co., Ltd. held a working meeting in 2022 to commend the advanced units of the bid creation work in 2021. In 2021, the company's 53 indicators reached an all-time high. Among them, the comprehensive energy consumption of copper and crude lead in tailings, the life of roaster kiln, zinc in lead mud and silver in tailings are the best in the industry.

Yuguang took the lead in the industry to create a first-class safety, first-class environmental protection, first-class quality, first-class indicators, first-class management, first-class culture, first-class environment of China's non-ferrous smelting benchmark enterprises. In 2021, the company will firmly establish the concept of "chasing the first, creating the first, and ensuring the first", adhere to high-position planning, high-standard calibration, high-quality promotion, comprehensive benchmarking industry leadership and historical excellence, and innovate and apply PDCA (planning, implementation, inspection, action) management model to continuously improve the standard-creating work system. The factory directors, section leaders and team leaders of the company fully mobilize the enthusiasm of the staff and workers and make every effort to promote the development of the standard setting and standard creation work. First of all, they collect the indicators of the same industry at home and abroad, so that they know each other, and then compare them, and finally find out the gap, determine the goal of creating the standard, and achieve the continuous progress and transcendence of the key comparable indicators of the industry.

According to the problems in production, Yuguang Yuchuan smelter has further refined and improved the range of control parameters of key process control points on the basis of the existing post standardization list. including grinding concentration, fineness, flotation concentration, fineness, reagent ratio, flotation machine liquid level height control range, foam layer thickness, etc., reducing the index fluctuation caused by random operation of workers. In 2021, the qualified rate of copper content in tailings of the plant continued to increase and tended to be stable, achieving 0.24% copper content in tailings, the highest in history.

Yuguang No. 1 smelter decomposes several controllable indexes in the comprehensive energy consumption of crude lead, such as water, electricity, oxygen and pulverized coal as the main management measures. Combined with the team standardization work, the factory refines the boiler operation, equipment start and stop, process control and other aspects, the responsibility to the specific operation positions and personnel to ensure that everyone pays attention to the indicators. In 2021, the comprehensive energy consumption of crude lead in the plant is 228.41 kg per ton of standard coal, which is the best in the industry.

Yuguang Zinc Industry No. 1 Plant actively promotes the transformation from planned maintenance system to point inspection maintenance system, breaks the traditional thinking of one-year overhaul, finds out the bottleneck of system production and formulates corresponding countermeasures to promote accurate maintenance. The factory moves the production management gate forward, promotes raw material early warning, warehousing and batching management, realizes the reasonable collocation of impurities and small metals, and ensures the continuous and stable operation of the system from the source. In 2021, the life of the roasting furnace in the first plant of zinc industry is 546 days, and the longest life of the same type of roaster in the same industry in China is 530 days, which is the best in the industry.

Cheng Lijun, head of the third plant of Yuguang zinc industry, led the whole plant to take team standardization as the starting point, pay close attention to detail management, and pay close attention to the silver content of tailings. Throughout the year, tailings contain 40.85 grams of silver per ton, exceeding the industry's best silver content of 57 grams per ton. Lead mud in the leaching section contains 2.03% zinc, exceeding the industry's best 2.80%.

Yang Anguo, chairman of Yuguang Group, pointed out: "to create a standard is to create efficiency, and only by creating efficiency can we increase income." In recent years, by carrying out benchmarking and other work, we have better realized the quality change, efficiency change and power change of enterprise development. This year, Yuguang will adhere to the goal of creating standards, continue to focus on the direct yield of major metals, recovery, energy consumption and other indicators, and maintain the advantage of expanding industry leadership.
