Recently, Chongqing Bosesai Mining (Group) Co., Ltd. (referred to as “Bosesai Group”) plans to invest another 11.5 billion yuan in Wanzhou to carry out two projects: the intelligent upgrading of alumina production and capacity replacement, as well as the construction of a new green circular industry integrating coking, electricity generation, and chromium production. Previously, the 3.6 million-ton special aluminum new material project invested and implemented by Bosai Group in Wanzhou was completed and put into operation, generating output value of 7.46 billion yuan last year. In January 2020, Bosai Group took advantage of Wanzhou’s strengths in river transportation and logistics, and signed an investment agreement with the people’s government of Wanzhou District for a project involving 3.6 million tons of special aluminum new materials, with a total investment of 7.5 billion yuan. As a result, Chongqing Jiulong Wanbo New Materials Technology Co., Ltd. (hereinafter referred to as Jiulong Wanbo) was established. Kowloon Wanbo will construct four production lines using the low-temperature leaching Bayer process, with an annual production capacity of 900,000 tons each, in one go. These lines will be equipped with a 5G intelligent system, systems for the comprehensive recovery and utilization of waste heat and by-products, as well as environmental protection and fire safety facilities. This is the largest key industrial project to be invested in in Wanzhou in recent years, with environmental protection measures alone costing 500 million yuan. Kowloon Wanbo uses the most advanced Bayer process technology in the alumina industry today; its equipment is large-scale and integrated, with a standard coal consumption of only 290 kilograms per ton of alumina, which is significantly lower than the 370 kilograms used in the same industry. A responsible official from Kowloon Wanbo said that, building on the existing production capacity of 3.6 million tons of alumina, the facility will undergo intelligent upgrades and capacity replacement, resulting in an additional 2 million tons of production capacity. By the end of 2023, the alumina production capacity will reach 4.6 million tons, and by the end of 2024 it will reach 5.6 million tons, generating an additional revenue of 6 billion yuan. Not long ago, Bosai Group decided to invest another approximately 6 billion yuan in Wanzhou to establish a green circular industry project integrating coking, electricity generation, and chromium production, following the Jiulong Wanbo Special Aluminum New Materials project. This new project will have an annual production capacity of 1.8 million tons of coke and 650,000 tons of ferrochromium. Coke is produced through carbonization, and this coke is used to manufacture high-carbon ferrochrome, thereby gradually establishing a complete industrial chain of “coke + electricity + ferrochrome + iron smelting + stainless steel”. The main products of this project are coke and ferrochrome. A small portion of the coke is used directly in the production of ferrochrome, while the remaining coke and ferrochrome are all sold to steel mills and stainless steel plants along the Yangtze River as well as in the Yangtze River Delta and Pearl River Delta regions. Transportation is mainly by water, which results in lower logistics costs. It is understood that the integrated green circular industry project for coking and chromium production is the first of its kind in the country. It adopts an integrated production approach that combines coking, power generation through comprehensive resource utilization, and ferrochromium smelting. Coking is carried out using negative-pressure heat recovery, which represents a combined coking and electricity generation production process. During this production process, no phenol-cyanide wastewater, hazardous waste, or dangerous chemical products are generated, and there are no emissions of toxic or harmful gases. Compared to other processes for producing the same amount of coke and electricity, the negative-pressure heat recovery coking process can also significantly reduce carbon dioxide emissions. It is recognized as an environmentally friendly method for coke production and holds a strong competitive advantage in the industry. The reporter learned that the project can also generate electricity using the waste heat produced during the coking process, as well as the clean gas obtained after dust removal during the chromium ore reduction process; the annual electricity production amounts to about 2.1 billion kWh, all of which is used for the integrated coking, electricity generation, and chromium production project. Officials from Wanzhou District said that the project aims to start construction by the end of this year and begin operations by the end of 2024. Once fully operational, it is expected to generate an annual output value of around 12 billion yuan, as well as annual tax revenues of about 500 million yuan, while also creating more than 1,000 job opportunities.
