On the basis of this, a wholly-owned subsidiary was established in Chongyang in March 2006. On April 28 of the same year, the ground-breaking project for stone and vanadium extraction was started.

1. Industrial background of pilot projects The grades of stone coal and vanadium mines in China vary considerably, with 60% of grades below 0.5%. Strictly speaking, grades below 0.8% are not suitable for industrial production. Hubei Province is a large province of stone coal vanadium ore, with high grade, and comprehensive development and utilization of stone coal has broad development prospects. At present, there are more than 20 vanadium extraction enterprises in the country, and the production scale is mostly 100-200 tons per year. The production process is flat kiln sodium roasting. The traditional stone coal vanadium extraction process is facing elimination due to the existence of two fatal defects. It is also the two world-wide technical problems that are common in the stone-steam extraction industry: one is the pollution control problem; the other is the problem of increasing the conversion rate and recovery rate of vanadium. Hubei Hanhai Mining Investment Co., Ltd. invested more than 35 million yuan to set up its own R&D center, and built a stone coal-raising pilot base with a design capacity of 300t/y vanadium pentoxide in the mining area. After more than three years of technical research, a new set of new processes for the extraction of vanadium from stone coal has been successfully developed. The process has three national invention patent technologies, which completely solves the above two technical problems and realizes the continuous industrial production of safe and environmentally friendly vanadium extraction. 2. Approval of project approvals Chongyang County Development and Reform Commission's project record for the pilot project Chongyang Hanhai Mining Development Co., Ltd. 3, the stone coal vanadium pilot project production line pilot site real-life map through the Hubei Provincial Department of Land and Resources and Chong Approved by the Yangxian County People's Government, Hubei Hanhai Mining Investment Co., Ltd. invested in a production line with a designed capacity of 300t/y vanadium pentoxide in Xiaoyuanchong Mining Area. The production line adopts a new process of introducing vanadium from environmentally friendly stone coal with independent intellectual property rights researched by Hanhai Mining. The production line started on April 28, 2006. After more than two years of pilot work such as civil construction, equipment installation and process commissioning, more than 4,000 hours of rotary kiln roasting, the exhaust emission reached the national standard, and the product recovery reached the design goal. It fully proves that the new process can solve two major problems in the process of extracting vanadium from stone coal. At present, the pilot work is nearing completion, and the company plans to finance large-scale production.

4. Key scientific and technological research projects The 2007 pilot projects were selected by the Science and Technology Department of Hubei Province as key scientific and technological projects. Domestic experts and scholars have high hopes for the research topics of the project. The industry calls it a revolutionary experiment in the stone and vanadium extraction process. Provincial Science and Technology Department Science and Technology Research Project Query Website (Project No.: 2007AA101C66) The pilot project has stood out from a large number of declared projects. The Provincial Science and Technology Department allocated 40,000 yuan as project funds to encourage research and development of the project. 5. Pilot project innovation process (three items) National invention patent technology) The rotary kiln is the first in the domestic trial roasting equipment. It has the advantages of small floor space, large processing capacity and elimination of disorderly discharge of exhaust gas. Compared with the existing traditional processes, the process determined by the pilot project has different characteristics and innovations, which are manifested in three aspects: 1) The new environmentally friendly composite additive for stone and vanadium roasting replaces the salt and calcium to roast, and solves the chlorine gas. The source of hydrogen chloride gas, vanadium conversion rate of more than 70%, up to 75.2%. 2) Resin in the process of extracting vanadium from stone coal vanadium ore. The pulp ion exchange uses D-XXX macroporous weakly basic anion resin. The resin flows upward from the lowest-end adsorption exchange tank with the lowest position, and realizes the slurry. Dynamic countercurrent exchange, the resin is saturated and then enters the next process. Compared with the conventional process, the total recovery of vanadium is increased from 30 to 40% to 60 to 65%. 3) New technology for control and treatment of roasting waste gas from stone coal vanadium ore. The exhaust gas generated by the rotary kiln roasting is absorbed by the dry cyclone dust removal and turbulent foam absorption tower with different absorption liquids, so that the exhaust gas discharge reaches the standard.

6. Resources of the two vanadium mining areas of Chongyang Company 1) Xiaoyuan Chongyan Mine is located in Guihuaquan Town, Chongyang County. The exploration license number is 4200000730198, and the registered area of ​​mineral rights is 1.90 square kilometers. The ore reserves were found to be 2 million tons, the average grade (V2O5%) was over 0.8%, and the V2O5 reserves were 16,000 tons. The potential amount of vanadium metal is expected to be between 3 and 4 million tons (according to the current market economy value of more than 6 billion). The exploration unit has completed the detailed investigation report of geological exploration. 2) Wanjiakou vanadium mine is located in Dayuan Township, Chongyang County. The exploration license number is 4200000730199, and the registered area of ​​mineral rights is 5.99 square kilometers. The ore reserves were found to be 1.3 million tons, with an average grade of 1.0% or more and a vanadium metal content of 12,000 tons. The potential vanadium metal is more than 80,000 tons (economic value is 16 billion). The exploration unit has completed the detailed investigation report of geological exploration. 7. Economic Benefit Analysis of the Pilot Project The existing pilot production line with a designed capacity of 300t/y vanadium pentoxide is 120-130t/y due to the limitation of the capacity of the roasting equipment. On the basis of the original production line, a new investment of 6 million yuan is mainly used to add 1 φ3×42m rotary kiln and supporting facilities, which can actually reach a production capacity of 300t/y. According to the technical and economic indicators of the vanadium-vanadium mine pilot production line, the current market price is 200,000 yuan/ton, the production cost is 100,000 yuan/ton, and the annual profit is more than 30 million yuan. 1.
