In the field of chemical industry, the company has been committed to the development and application of non-ferrous metal-related chemical projects such as salt lake lithium extraction, ore lithium extraction, comprehensive recovery of waste batteries and waste residue resources, clean vanadium extraction, flue gas acid production, flue gas treatment, and proprietary equipment, etc., with "new process for selective and efficient extraction and separation of lithium products from salt lake brine", "lepidolite salt replacement lithium extraction and comprehensive utilization technology", "gas separation pre-conversion high concentrationSO2 A number of technological achievements represented by "flue gas acid production technology" have reached the domestic leading level, and a number of classic benchmark projects have been successfully created.
In the field of nonferrous metallurgical furnaces, Changsha Nonferrous Institute has successfully developed a series of metallurgical furnaces with independent intellectual property rights and core competitiveness, such as lead flash melting furnace, oxygen-enriched side blowing furnace, copper top blowing furnace, fluidized roasting furnace, fuming furnace, continuous refining furnace, multi-stage roasting furnace, continuous blowing furnace, ISF furnace, lead/zinc rain condenser, distillation tower, electric furnace, rotary side blowing furnace, anode furnace, etc. These core technologies and equipment have been widely used in industries and fields such as copper, lead, zinc, tin, nickel, antimony, zinc leaching slag, and copper-containing solid waste. A number of high-quality projects have been built, leading the development of the non-ferrous metallurgical furnace industry and making important contributions to the improvement of equipment technology level in the non-ferrous industry.
Large Mixing Project of Nickel Smelting and Metallurgy (Indonesia)
In the Indonesia base project of Qingmeibang nickel separation and smelting, the supply equipment of Zhongji Sunward exceeds 0.3 billion yuan, of which the high-efficiency mixing equipment has a maximum specification of Φ 18 × 20m.
Exhaust gas scrubbing equipment
After years of experience, Zhongji Sunward Technology Co., Ltd. and CINF Engineering Corporation Limited have developed proprietary technology and complete sets of equipment for the characteristics of hydrometallurgical tail gas, which are applied to the treatment of pressure leaching system exhaust steam, so that it can be discharged after reaching environmental protection standards. Specially designed for the "non-condensable gas and steam mixture" discharged from the pressure leaching system, the washing efficiency reaches more than 99%; the complete set of equipment integrates the functions of liquid storage, gas-solid centrifugal separation, and multi-stage washing. It has the advantages of compact structure, high washing efficiency, not easy to block, convenient maintenance, safety and reliability. At present, the technology has been applied to non-ferrous metal smelting, steel plants, new energy raw material smelting enterprises.
The main function of the anode cleaning and flapping Machine unit is to transport the anode plate, clean the anode mud with high pressure water and reshape the anode plate. It is one of the core equipment of the zinc electrolysis workshop. For cast zinc electrowinning anode plates that do not need to be flattened, automatic batch chain beating can be carried out, which greatly improves the treatment efficiency of the anode and realizes the automatic operation of the zinc electrowinning workshop equipment.
Upgrading Project of 220kt/a Zinc Electrodeposition Workshop in a Developed Country(备)
In 2022, it will undertake the upgrading and transformation of a complete set of process equipment in a zinc electrowinning workshop in a developed country that has been in operation for more than 40 years and has an annual production capacity of 220000 tons.
