KY3O1 environmentally friendly flocculant is an inorganic polymer flocculant that can strongly attract colloidal particles. Through adhesion, bridging, and cross-linking, it promotes colloidal coagulation. At the same time, chemical and physical changes occur, neutralizing the surface charges of colloidal particles and suspended solids, reducing the potential, and causing colloidal ions to attract each other, damaging the stability of micelles, promoting colloidal particle collision, and forming flocculation precipitation. Through the separation experiments of lead and floating copper in different mines and multiple comparative experiments with traditional lead inhibitor potassium dichromate, our independently developed inhibitor has a more significant effect. Main advantages and fields: non-toxic, fast flocculation and settling speed, not affected by water temperature, applicable range; Used to treat industrial wastewater, domestic wastewater, mining tailings dams, promote water quality clarification, and accelerate the sedimentation rate of sludge.
Xi'an Kuangyuan Nonferrous Metallurgical Research Institute conducted a large number of targeted experiments on a copper lead zinc mine in Indonesia at our metallurgical technology research and development center, and ultimately successfully overcame the difficulty of copper lead separation using non-toxic combination reagents. At the same time, a large number of comparative experiments were conducted on copper lead ores with different properties, and the results showed that the non-toxic combination agent KY101 is an innovative product that can completely replace potassium dichromate. KY101 is an environmentally friendly and non-toxic agent for copper lead separation that our company has completely independent intellectual property rights. It is an environmentally friendly product that can completely replace highly toxic potassium dichromate. This product is non-toxic, environmentally friendly, and has stable performance. It is suitable for separating copper lead mixed concentrates and is a good medicine for suppressing lead in floating copper. Main advantages and fields: Used in the mineral and industrial wastewater industries, it can effectively carry out solid-liquid flocculation and sedimentation, and the sedimentation time is much lower than that of ordinary flocculants in the industry; Low cost, non-toxic, and short settling time.
Copper lead separation has always been a major challenge in the mineral processing industry. Traditional copper lead separation and copper float suppression methods include sodium cyanide method and sodium mercaptoacetate or its upgraded agents. Sodium cyanide can cause serious environmental pollution, while sodium mercaptoacetate is particularly sensitive to drug removal efficiency and dosage, making it difficult to control in actual production. The R&D team of Xi'an Mining Resources is dedicated to researching copper lead separation reagents. After extensive experiments, following the KY301 lead inhibitor, KY302 copper inhibitor has been developed. This drug can completely replace traditional drugs such as sodium cyanide and sodium thioacetate. When it contains secondary copper, it can be combined with zinc sulfate for better results.
The full process automation control system is a large and complex control system, with digital twins as the core and data integration as the foundation. It is an organic combination of crushing automation control, grinding and grading automation control, sorting automation control, and concentration and filtration automation control. Our hospital provides a fully automated control system for the entire process, which is a highly adaptable automatic optimization system that stabilizes the ore dressing production process. While ensuring product quality, it significantly improves the production capacity of the ore dressing plant, reduces energy and material consumption, and improves metal recovery rate. A large amount of instrument installation and debugging, extensive data collection and analysis, and complex software programming work are required in the entire process automation control system.
The pipeline sampling machine mainly consists of a sampler, sampling tube, valve, electric motor, and control system. Among them, the sampler is the core component of the entire sampling machine and the key to achieving the sampling function. The working process of the pipeline sampling machine includes the start of the control system, the operation of the motor, and the operation of the sampler. Firstly, the control system is started, controlling the motor to start and drive the sampler to work. The sampler moves inside the pipeline and brings the fluid to be sampled into the sampling tube. When the fluid passes through the sampler, the sampler will suck a portion of the fluid into the sampling tube. This sampling method can ensure the accuracy and reliability of sampling. The sampling principle of the pipeline sampling machine is based on the principle of inertial separation. Specifically, when the fluid leaves the main pipeline and enters the sampler, due to the geometric structure of the pipeline and the force of the fluid, there will be a certain separation effect of the fluid. At this point, fluids containing solid particles or suspended solids will be sucked into the sampling tube, ensuring the accuracy and reliability of sampling.
After starting, the automatic belt sampler is decelerated by the motor through a reducer, which drives the rotary arm shaft to rotate in a circular direction, allowing the sampling head at the front end of the rotary arm to take full section samples of the material on the belt. The central primary sampling machine is installed in the middle of the coal conveyor belt and is directly controlled by PLC. The material in the middle of the belt is cut across the entire section according to the set time interval. The material is fed into the belt feeder through the chute, and the belt feeder uniformly and continuously feeds the material into the crusher. The crusher crushes the material according to the specified particle size. The crushed material is divided by a reducer, and the sample is automatically collected. The final sample is used for the determination of moisture and composition samples in the laboratory, and the remaining material is returned to the currently running belt. The system mainly consists of central sampling machine, primary feeder, crusher, secondary feeder, splitter, sample collector and other equipment.
An automated dosing machine is an accurate quantitative mining dosing device that is remotely controlled and adjusted automatically. It is mainly used for the quantitative automatic addition of various mining chemical ore flotation reagents (such as xanthate, amine xanthate, sodium sulfide, No. 2 oil, copper sulfate, oleic acid and other foaming agents, collectors, adjusters, etc.). In order to obtain the best process indicators, our researchers improve the accuracy and reliability of the dosing measurement control system, which not only saves chemicals but also reduces the contact between dosing workers and harmful chemicals. Therefore, the system can achieve automatic addition, adjustment, and metering of drugs during the process. The automatic dosing system of the charcoal pulp plant is a complete set of equipment that integrates automatic control of chemicals, mixing of chemicals, and addition and release of chemicals. Automatically select the dosing plan based on the water quality data returned by relevant sensors for treatment. According to the dispensing plan, the system mixes the drugs in proportion. The stoichiometric pump adds relevant chemicals at a precisely controlled rate.
Xi'an Kuangyuan Nonferrous Metallurgical Research Institute Co., Ltd. has undertaken a beneficiation experimental research project for a fluorite mine in Inner Mongolia. The fluorite mine is a quartz calcite type fluorite mine, with fluorite grades of 20-30%, quartz 20-25%, and calcite of about 5% in the original ore, making it difficult to select fluorite mines.
