董事长专访｜山东鸿承集团刘泽铭：做好“黄金危废终结者”

Core Viewpoint - Shandong Hongcheng Group has transformed hazardous gold tailings into high-quality sulfur iron concentrate through a multi-stage flotation enrichment process, establishing itself as a leader in hazardous waste treatment in Hong Kong's stock market within 12 years of its founding [1][3]. Group 1: Company Background and Development - Founded in 2013 with a registered capital of 38 million yuan, Hongcheng Group was initiated by Liu Zeming, who was inspired by the potential of resource recovery from gold tailings [4]. - The company faced significant challenges in its early years, with two consecutive years of underperformance after its 2014 production launch, but achieved a breakthrough in 2017 with a utilization of over 500,000 tons of gold waste and revenue of 100 million yuan [4]. - By 2021, the company had transitioned from struggling to industry leader status, successfully listing on the Hong Kong Stock Exchange [4]. Group 2: Technological Innovations - The company developed a proprietary technology called "Selective Waste to Treasure Sulfur Iron Resource Efficient Enrichment Technology," which purifies sulfur and iron content from cyanide tailings from 40% to over 90% [6]. - The technology processes 1.2 million tons of tailings annually, producing 600,000 tons of sulfur iron concentrate with an annual revenue of 210 million yuan [6]. - The sulfur recovery rate from the process reaches 92%, and the sulfur content in the tailings is reduced to below 5%, exceeding national first-class product standards [6]. Group 3: Industry Impact and Future Plans - Hongcheng Group aims to create a complete gold industry chain, focusing on the high-value utilization of high-silica flotation tailings, which amount to millions of tons annually in Shandong [6][8]. - The company has initiated a project to process 1 million tons of high-silica flotation tailings, converting residual materials into construction aggregates and recovering iron elements [7]. - Future plans include establishing a comprehensive cyanide tailings utilization industrial park, with projects for producing 200,000 tons of nano-silicon-based materials and 600,000 tons of low-carbon cementing materials [10].
