Mineworm environmentally friendly gold extraction agent is an efficient gold extraction agent developed specifically for the wet leaching process of gold ore (pool leaching, heap leaching, charcoal slurry). Mineworm environmentally friendly gold extraction agent has the universality of general easily leachable gold ore (replacing traditional sodium cyanide), and has certain anti-interference ability for elements containing copper, lead, zinc, arsenic, carbon and other serious interferences or consumption agents. The use of an enhanced combination of "Mineworm gold extraction agent+specialized leaching aids" can further improve the indicators of gold. The mineral insect environmental gold extraction agent has been used in Xinjiang, Gansu, Hainan, Yunnan, Liaoning, Henan, Qinghai, Laos, Myanmar and other places. After extensive on-site use and repeated adjustment of the drug formula, the effect has been further improved, the performance is stable, and the cost-effectiveness is reasonable.
KY301 environmentally friendly flocculant is an inorganic polymeric flocculant that strongly attracts colloidal particles. Through adhesion, bridging, and cross-linking, it promotes colloidal aggregation. Simultaneously, it undergoes chemical and physical changes, neutralizing the surface charge of colloidal particles and suspended matter, lowering the potential, thereby causing colloidal ions to attract each other, disrupting the stability of the flocs, and promoting particle collision to form flocculated sediment. Through lead and copper separation experiments in different mines and multiple comparative tests with traditional lead inhibitors such as potassium dichromate, our independently developed inhibitor shows a more significant effect. Main advantages and applications: non-toxic, fast flocculation and sedimentation, unaffected by water temperature; applicable to a wide range of conditions; used to treat industrial wastewater, domestic wastewater, and mine tailings dams, promoting water clarification and accelerating sludge settling.
The Xi'an Mining Source Non-ferrous Metallurgy Research Institute has conducted a large number of targeted tests on a certain copper, lead, and zinc mine in Indonesia at our beneficiation and metallurgy technology research and development center, and finally successfully used a non-toxic combination of reagents to overcome the difficulties in copper and lead separation in this mine. At the same time, a large number of comparative tests were conducted on copper and lead ore of different properties, and the test results all show that the non-toxic combination reagent KY101 is an innovative product that can completely replace the highly toxic potassium dichromate. KY101 is a non-toxic and environmentally friendly reagent for copper and lead separation developed by our company and has full independent intellectual property rights. It is a completely environmentally friendly product that can completely replace the highly toxic potassium dichromate. This product is non-toxic, environmentally friendly, and has stable performance. It is suitable for the separation of copper and lead mixed ore and is a good medicine for inhibiting lead in copper浮选. Main advantages and fields: It is used in mineral resources, industrial wastewater industries, and can effectively carry out solid-liquid flocculation precipitation, with a precipitation time far lower than that of ordinary flocculants in the industry; low cost, non-toxic, short precipitation time.
Copper and lead separation has always been a major problem in the beneficiation industry. The traditional separation of copper and lead, inhibiting copper and floating lead: sodium cyanide method and sodium thiosulfate or its upgraded reagents, sodium cyanide will cause serious pollution to the environment, sodium thiosulfate is particularly sensitive to the effect of drug removal and the amount of drug, which is difficult to control in actual production. The professional R&D team of Xi'an Mining Source is committed to the research of copper and lead separation reagents, and after a large number of tests, after the KY301 lead inhibitor, the KY302 copper inhibitor has been developed. This reagent can completely replace the traditional sodium cyanide and sodium thiosulfate and other reagents. When there is secondary copper, it can be matched with zinc sulfate, and the effect will be better.

The pipeline sampler mainly consists of a sampler, a sampling tube, valves, a motor, and a control system. Among them, the sampler is the core component of the entire sampler and is the key to achieving the sampling function. The working process of the pipeline sampler includes the startup of the control system, the operation of the motor, and the operation of the sampler. First, the control system starts, controls the motor to start and drive the sampler to work. The sampler enters the pipeline and moves, bringing the fluid to be sampled into the sampling tube. When the fluid passes through the sampler, a part of the fluid is sucked into the sampling tube. This sampling method can ensure the accuracy and reliability of the sample. The sampling principle of the pipeline sampler 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 action force of the fluid, the fluid will produce a certain separation effect. At this time, the fluid containing solid particles or suspended matter will be sucked into the sampling tube, ensuring the accuracy and reliability of the sample.
The belt automatic sampling machine is driven by a motor through a reducer to rotate the swing arm shaft, so that the front end of the swing arm takes samples of the material on the belt. The middle primary sampling machine is installed in the middle of the coal belt machine and is directly controlled by PLC. It takes samples of the material in the middle of the belt machine at a fixed time interval. The material taken is entered into the belt feeder through the chute, and the belt feeder evenly and continuously feeds the material into the crusher. The crusher crushes the material according to the specified particle size. The crushed material is subdivided by the subdivider, and the samples are automatically collected. The final sample is used for moisture and composition sample determination in the laboratory, and the remaining material is returned to the current running belt. The system mainly consists of a middle sampling machine, a primary feeder, a crusher, a secondary feeder, a subdivider, a sample collector and other equipment.
The automated dosing machine is a precise quantitative mining dosing device that is remotely automatically controlled and regulated. It is mainly used for the quantitative automatic addition of various mining chemical flotation reagents (such as yellow reagent, amine yellow reagent, sodium sulfide, No. 2 oil, copper sulfate, oleic acid, etc.) for ore dressing. Our researchers aim to obtain the best process indicators by improving the accuracy and reliability of the dosing metering control system. This not only saves reagents but also reduces the contact between dosing workers and harmful reagents. Therefore, the system can achieve automatic addition, adjustment, and metering of reagents in the ore dressing process. The automated dosing system in the carbon pulp plant is a complete set of equipment that integrates automated control of reagents, reagent mixing, and reagent addition. Based on the water quality data returned by relevant sensors, the system automatically selects the dosing scheme. According to the dosing scheme, the system mixes the reagents in proportion. The chemical metering pump adds the relevant reagents at a precisely controlled rate.
