SMM12 March 4: today, at the 2020 non-ferrous metals industry annual meeting and long contract Carnival jointly held by SMM (SMM) and China Renewable Resources Industry technological Innovation Strategic Alliance. Lu Dong, general manager of Shandong Hengbang smelting Co., Ltd., Shanghai Qianbang International Trading Co., Ltd., brought a speech with the theme of "". He mainly elaborated on the development status of rare and precious small metals and the production process characteristics of rare and precious small metals in the company. at the same time, he also predicted the development direction of rare and precious small metal smelting technology in the future.
Production characteristics of rare and precious small metals in the company
The use of "one-step smelting antimony" reduces the production time of antimony white, avoids energy waste, metal loss and environmental pollution caused by repeated oxidation and reduction of metal antimony, and improves the recovery rate of antimony metal.
The "vacuum distillation" technology is applied to the precious metal smelting process, which speeds up the treatment of lead anode slime, reduces the refining cycle of silver separation furnace, and reduces the backlog of gold and silver in the intermediate material.
The arsenic-containing materials in the smelting process are opened up with metal arsenic, high-purity arsenic and other products, which can reduce the harm to the environment to the greatest extent.
The company will continue to promote the research and development of 7N high purity antimony, 6N high purity bismuth and 7N high purity tellurium.
Market and application direction
At present, the demand for primary products of antimony, bismuth, selenium and tellurium on the market tends to be saturated.
With the improvement of the overall technical level of the country, high-purity metals are more and more widely used in semiconductors, aerospace, aerospace and other sophisticated fields, and there is still a large demand in the market.
Development Direction of smelting Technology of rare and precious small Metals
The coexistence of many kinds of smelting processes and the coordinated development of new technologies will be the development trend of rare and precious small metal smelting technology, such as the combined treatment process of fire and wet process, the application of vacuum technology, the continuous production of rare and precious small metals, etc.
The technologies of short process "one-step antimony smelting" and "vacuum distillation" will be gradually popularized and applied in the field of rare and precious small metal smelting.
The high purification and high purity compounds of rare and precious small metals will be the expansion of the application of rare and precious small metals, especially with the development of high and new technology and special materials, the requirements for the variety, specification and purity of rare and precious small metals are higher and higher.
Efficient treatment and resource utilization of arsenic materials is an urgent problem to be solved in the industry, and solid waste containing arsenic has become a common problem and problem faced by the industry.
Company profile
The company was founded in 1988 and was restructured into a joint stock limited company with the approval of relevant government departments in February 1994. it was listed on the Shenzhen Stock Exchange in May 2008 (stock code: 002237). It became a holding enterprise of Jiangxi Copper Co., Ltd in 2019.
After 30 years of innovation and development, the company has established a complete industrial system integrating "prospecting, mining, mineral processing, smelting, refining and deep processing", and has begun to lay out in the field of high-purity metal new materials such as semiconductor materials.
The company has more than 6000 employees and total assets of 15 billion yuan. In 2019, the main business income was 28.536 billion yuan and the total profit was 349 million yuan. Ranked 335 among China's Fortune 500 companies in 2020
