Our aim is to create a better tomorrow, and our responsibility is to protect environment for the society.

We have focused on sustainable development of the nonferrous metals industry when performing R&D work, and put our priorities on key technology R&D and popularization for energy efficiency and environmental protection in this industry:

Ø The process of oxygen bottom-blown smelting – reduction smelting of lead in blast furnace makes the comprehensive energy consumption being the highest level of the world.

Ø The new technology of oxygen bottom-blown smelting - side-blown direct reduction of liquid lead slag based on the process of oxygen bottom-blown smelting - reduction smelting of lead in blast furnace makes the comprehensive energy consumption being the highest level of the world.

Ø For the technology of copper smelting with bottom-blown oxygen, no additional fuels are required during the smelting process.

Ø The bottom-blown continuous copper matte converting technology has effectively addressed the current worldwide problem, i.e. fugitive SO2 at low altitudes during converting in PS converter;

Ø The introduction of the rotary kiln - electric furnace technology into China has changed the backward ferro-nickel smelting method, small equipment capacity, high energy consumption, low-grade ferro-nickel, high impurity content, poor environment and severe pollution in China;

Ø Take the lead in establishing China's first largest industrial demonstration line with independent intellectual property rights and closed cycle, and achieving low energy consumption and harmless production of polysilicon.

Ø Conduct studies of the dust collection system, improve its design, and make the technology characterized by a short process, low energy consumption, etc.

In the project design, construction and operation process, we always adhere to standard designs, stable operation, standardized emissions and information disclosure to achieve harmonious development of the living environment, social responsibility and economic benefits.

In production and business activities, we establish environmental management systems based on internationally recognized standards, identify potential environmental factors, make plans, implement controls, meet regulatory requirements and achieve sustainable development.
