Italian Tannin GIant Silva Group Comes into China Green Mine Market

On 10th May 2025, Dr. Guo Linxia, Founder of Hanlin Global, Yang Zuolin, General Manager, Zhang Yu, Deputy General Manager and Zhao Songbo, Ecology Expert of Hanlin Think Tank, met with Sergio Conti, President of Silva Group China, and Pu Anzhi, Country Manager of Silva Group China, in Beijing. Silva Group, the world's leading tannin company with 171 years of history, and Hanlin Global, the green pioneer of China's mining industry, are closely linked to start a new track of green transformation in the mining industry.

Silvateam is a "century-old giant" in the tannin field. Founded in 1854, Silvateam has built up an industrial matrix covering subsidiaries such as SILVACHIMICA, LEDOGA, INDUNOR, etc., and set up production bases in Italy, Argentina, Peru, etc., and its products are sold well in more than 60 countries around the world, making Silvateam the leading company in the industry of all kinds of plant tannins. Today, this century-old company is extending its tannin technology to the field of mining and environmental protection with disruptive innovation.

"Tannins are a natural green mining solution!" Sergio Conti, President of Silvateam, pointed out during the meeting that as natural polymer compounds, tannins show irreplaceable advantages in enhancing metal recovery and reducing pollution of mineral processing chemicals, which is highly compatible with the demand for green transformation of the global mining industry. Silvateam hopes to develop the green mining market in China together with Hanlin Global by virtue of its global leading technology system.

Dr. Guo Linxia responded that Hanlin has developed core competencies in sustainable mining, beneficiation, R&D, ecological remediation, bioleaching technology, etc. based on its mature mining technology service system, which has great potential for synergy with Silvateam's tannin-assisted beneficiation solutions. The two sides intend to launch two important cooperation plans: one is to set up a joint laboratory with top universities in the United Nations to study the improvement of tannin beneficiation chemicals; the other is to select typical mines in China to build intelligent chemical dosage system demonstration projects, which will provide localised data support for the landing of tannin technology in China.

This cooperation is called the industry change "catalyst". According to professional data, if the tannin technology is successfully applied, it will reduce the energy consumption of mine flotation by 15-20% and effectively control the pollution of acidic wastewater. Hanlin International has always been committed to green mines and ecological restoration, and the cooperation with Silvateam not only creates a precedent in the cross-border application of biobased materials, but also sets a new benchmark for international technical cooperation under the goal of "dual-carbon", which will surely push China's mining industry towards the road of high-quality development with green and low-carbon.
