On July 10th, geological expert Mr. Li came to our institute for training on mining knowledge such as exploration, mining, and beneficiation. During the training period, Mr. Li explained professional theoretical knowledge to all staff members of our institute. Our staff listened attentively and thought carefully, and consulted Mr. Li for any questions they did not understand. Mr. Li answered questions with humor and wit.

In the later stage of the training, Mr. Li talked about the issues of mine greening and comprehensive resource utilization. "Mine greening" refers to the comprehensive treatment of geological environmental problems caused by mining through the use of engineering, biological and other technological means, in order to achieve stable geological environment and restore ecological environment in mines. The commonly used methods for mine greening include soil cover greening, retaining wall slope greening, excavation platform greening, slope drilling greening, fish scale pit soil storage greening, hanging net spraying greening, ecological bag greening, ecological grass carpet greening, floating platform greening, and planting concrete greening. The comprehensive treatment and utilization project of tailings resources is a key research and development project of our institute in recent years. Currently, we have participated in the development and investment of several tailings projects for different non-ferrous and precious metals both domestically and internationally.

The comprehensive management and circular utilization of tailings resources are the persistent goals of our institute. In response to national policies, we promote the construction of standardized green mines, formulate standards and related methods for green mine construction, establish typical green mines, promote green mine construction models, and take a big step forward in the construction of green mines, promoting safe, environmentally friendly, a
