This series of patented equipment developed by our company in cooperation with Central South University is mainly adopted to treat arsenic alkali slag, arsenic filter cake, and other arsenic contented materials from copper smelter,lead smelter and zinc smelters. The main process is: hydrometallurgy + pyrometallurgy combined to turn the arsenic-containing hazardous wastes into pure arsenic trioxide, and then reduced to metallic arsenic, metallic arsenic can be sold according to local market demand or rigid landfill disposal. The main patented equipment of this process, As2O3 purification furnace and arsenic reduction furnace, is widely praised for its high level of environmental protection, high level of automation, and large treatment capacity during industrial application. Arsenic Reduction Furnace is a type of industrial equipment used in metallurgical processes to remove or reduce the arsenic content in ores, concentrates, or other materials. Arsenic is commonly found in copper, lead, and zinc ores and can pose environmental and health hazards if not properly managed. The reduction furnace typically uses high temperatures and specific reducing agents (such as carbon or hydrogen) to convert arsenic compounds (often in the form of arsenic oxide) into more stable or less toxic forms that can be safely captured or neutralized. Key Components: Reactor Chamber: The primary area where the thermal reduction process occurs. Heat Source: Often electric or fuel-based, it provides the necessary temperature to initiate the reduction reactions. Reducing Agent: Materials like carbon, hydrogen, or other chemicals that assist in breaking down arsenic compounds. Scrubber or Filter System: Captures or neutralizes the arsenic gas or vapor produced during the process to prevent atmospheric release. Applications: Mining and Metallurgy: Commonly used in smelters where copper, lead, or zinc ores are processed, and arsenic is a byproduct. Environmental Management: Helps reduce the risk of arsenic contamination in the environment by stabilizing arsenic compounds.

The principle of fuming is a reduction and volatilization process, which is to blow air and pulverized coal into the slag in the fuming furnace, generate heat and carbon monoxide after combustion, keep the slag at high temperature, and make the compounds and free ZnO and PbO in the slag reduced to Zn and Pb vapors, the vapor will rise to the upper space of the furnace, meet CO2 or inhaled air and oxidize to zinc oxide and lead oxide again, and are collected in the state of soot. The four walls of the fuming furnace are all composed of water jackets. The lowermost water jacket on the side is provided with a tuyere. The inner wall of the water jacket is welded with Φ16mm and 50mm long pins, and the distance between the nails is 50mm, so that the condensed slag adheres to it and forms slag layer protects the water jacket and reduces heat loss. There is a slag outlet on the water jacket at the front end of the furnace. The lower layer of the water jacket and the inclined flue are water-cooled and circulated, and the upper layer of the water jacket is cooled by vaporization. The tuyere structure adopts a tuyere with a ball valve, and there are two branch pipes. The one near the water jacket is called the primary air coal pipe, and the one outside is the secondary air pipe. In order to prevent pulverized coal from escaping out of the furnace, the secondary air pressure is slightly higher than the primary air pressure (about 100mmHg). There are three air outlets on the upper part of the furnace, which is convenient for operation and observation, and can inhale air oxidized metal vapor.   Fuming Furnace Operational In order to achieve good results in the fuming process, the following conditions must be well controlled:temperature, fuel and air supply volume, slag composition, molten pool depth.   1. Temperature If the temperature is too high (such as exceeding 1350°C), iron deposits or Zn-Fe, Sn-Fe alloys may be formed, which is harmful to the fuming operation. If the temperature is too low, the reduction rate of metal oxides will slow down, the volatilization rate will decrease, the fluidity of the slag will deteriorate, and there may even be a danger of furnace formation, so the temperature in the fuming practice is kept in the range of 1150-1300 °C.   2. Fuel and air supply volume The most active factor affecting the volatilization rate in the fuming process is the air supply volume. Because the temperature in the furnace, the ratio of CO/CO2, the amount of gas, and the vapor pressure of the metal are all related to the air supply volume. The volume of the air supply depends on the pulverized coal consumption and the air utilization coefficient (α). The larger the air utilization coefficient, the higher the thermal effect of the fuel, the greater the partial pressure of CO2, and the higher the temperature in the furnace; the smaller the air utilization coefficient , the thermal effect is reduced, the partial pressure of CO becomes larger, and the reducing ability is enhanced. Pulverized coal is both a reducing agent and an exothermic agent in the fuming process, so the CO/CO2 should have an appropriate ratio during combustion. The air utilization factor actually adopted by the factory is variable. Usually, at the beginning of fuming, an air utilization factor close to 1.0 causes almost all carbon to be burned into CO2 to increase the temperature of the slag. In the reduction stage, adjust the air utilization factor to make carbon into CO as much as possible to improve the reduction ability. 3. Slag composition In practical the actual zinc content of the slag feed into the fuming furnace should be >6%. Below 4%, fuming treatment is uneconomical. Regarding the effect of slag composition on the volatilization rate of zinc, it can be summarized as follows: The increase of CaO content can increase the volatilization rate of zinc; The increase of FeO content in slag has little effect on ZnO activity; The content of SiO2 increases, and the volatilization rate of zinc decreases. Therefore, the silicic acidity of the slag is preferably in the range of 1.1 to 1.2.   4. Molten pool depth The thickness of the slag layer in production is generally in the range of 700- 1000mm above the tuyere area.

As the demand for lithium-ion batteries (Li-ion) continues to grow, especially in electric vehicles (EVs), consumer electronics, and renewable energy storage, the need for efficient recycling processes has become increasingly important. Lithium battery recycling production lines are designed to recover valuable materials from used batteries, reducing environmental impact and providing a sustainable source of raw materials for new batteries. How a Lithium Battery Recycling Production Line Works Collection and Sorting Collection: Used batteries are collected from various sources, including EVs, consumer electronics, and industrial applications. Sorting: Batteries are sorted based on their chemistry (e.g., lithium cobalt oxide, lithium iron phosphate) and condition. This step is crucial because different battery chemistries require different recycling processes. Discharging Safe Discharge: To prevent fires or explosions during processing, batteries are fully discharged in a controlled environment. This step neutralizes the electrical energy stored in the batteries, making them safe for further handling. Shredding and Size Reduction Mechanical Shredding: Batteries are mechanically shredded into smaller pieces, breaking down the battery cells into fragments. This process separates the battery components such as the casing, electrodes, electrolyte, and separator materials. Size Reduction: Additional milling or grinding processes may be employed to further reduce the size of the particles, enhancing the efficiency of subsequent separation steps. Separation and Extraction Magnetic Separation: Magnets are used to separate ferrous materials, such as steel casings, from non-ferrous components. Hydrometallurgical Processing: Involves chemical leaching to dissolve and extract valuable metals like lithium, cobalt, nickel, and manganese from the shredded battery materials. The resulting solution is processed to recover these metals as salts or oxides. Pyrometallurgical Processing: High-temperature furnaces are used to smelt the shredded material, recovering metals in a more concentrated form. This process is often used for recovering cobalt, nickel, and copper. Purification and Refining Precipitation and Filtration: The dissolved metals are precipitated out of the solution, filtered, and purified. This step may involve multiple stages of refining to achieve high-purity metal compounds suitable for reuse in new batteries. Electrolysis: Metals like lithium can be further purified through electrolysis, where an electric current is used to deposit pure metal onto electrodes. Recovery of Non-Metallic Materials Plastics and Electrolytes: The plastics and separator materials are typically separated through flotation or solvent extraction techniques. These materials can be recycled into new products or safely disposed of. Graphite Recovery: Anode materials, often composed of graphite, can be recovered and processed for reuse in new battery anodes. lithium battery recycling plant Advantage: 1.
