The largest nonferrous metal mine in Qinghai

At 8 o'clock, the sun shines on the Xitieshan mountain on the northern edge of the Qaidam Basin, and the roar of machines has already resounded through the valley. Wang feizheng, a mining engineer with eight years of service, led the mining team to search for non-ferrous metal ore in the dark with rock drilling jumbo.

This is the operation site of Xitieshan branch of Western Mining Co., Ltd., which is located in the middle section of No. 2582 mine of Xitieshan lead-zinc mine. It is also the epitome of the gradual recovery of Qinghai nonferrous metal industrial production capacity.

Xitieshan lead-zinc mine, located in Haixi Mongolian and Tibetan Autonomous Prefecture of Qinghai Province, is the largest non-ferrous metal mine in Qinghai Province. It contains many kinds of non-ferrous metals such as lead, zinc, gold and so on.

Xitieshan branch's mining and beneficiation indexes are in the forefront in China, and the mine has reached a production capacity of 1.5 million tons per year. It is one of the independent lead-zinc mines with large mining and dressing scale in China. Wang Fei said.

In the beneficiation workshop of Xitieshan branch, the jaw crusher is crushing the raw ore transported from 1000 meters underground, and then it is sent to ball mill and semi autogenous mill through conveyor belts. But six months ago, affected by the epidemic situation, the company's production capacity was only 13.27% of the planned amount. The underground ore drawing of Xitieshan was about 1500 tons less than the original plan every day.

The transportation of mining supplies and concentrate materials of the company has changed from highway to railway "On the one hand, we should pay attention to the prevention and control of epidemic situation, and at the same time, we should pay attention to the guarantee of supply and stable production. With the normalization of epidemic prevention and control, the production capacity of our "green mine" has gradually recovered. " Western Mining Co., Ltd. Xitieshan branch party secretary, responsible person Cheng Wuzhong said.

In recent years, green development has become the key to the transformation of old and new kinetic energy and supply side structural reform of Xitieshan branch of Western Mining Co., Ltd.

In the new ore dressing plant, accompanied by the booming machine sound, 48 year old miner Yan RenQian is carrying out ore flotation. Before that, we did not even think of the dust pollution in the factory

The traditional mining technology brings high environmental load, and the extensive development mode relying on low-cost element investment is difficult to sustain. Cheng Wuzhong said.

Today, the company's annual waste water recovery rate reaches more than 90%, and the company's Tailings achieve zero pollution discharge. The recovery rate of the mine has also increased to more than 90%, and the comprehensive utilization rate of resources has been greatly improved.

"The equipment rate of the company's mineral processing automation equipment increased from 9% to 92%. Through the energy-saving transformation, the unit power consumption of the ore dressing plant has been reduced from 23.28 kwh per ton to 18.48 kwh per ton Cai Zeshan, general manager of Xitieshan branch of Western Mining Co., Ltd.

Mining technology innovation reduces industrial solid waste discharge and stabilizes mine production capacity. The improvement of beneficiation process has also greatly reduced the mineral processing cost, unit comprehensive energy consumption and clean water consumption. The unit full production cost in 2019 is 27.74 yuan lower than that in 2015.

"This year, the prices of lead and zinc ore products are down 19% and 24% respectively compared with the same period last year." Next, they will increase the treatment capacity and try to make up for the lack of production in the first half of the year, Cai said. We should not only ensure the normal operation of the company to achieve the planned objectives, but also seek innovative development among green mountains and green waters.
