Water treatment technology: The tailings pond is a large-volume sedimentation-storage pond that can be built on a dam, using slopes on slopes, slopes, rivers or flats. A drainage well and a drain pipe are arranged in the pool, or a drainage ditch is opened along the edge, and the tailings water is clarified and purified in the pool and discharged. The suspended solids in the tailings water are stored at the bottom of the tank. The wastewater stays in the pool for at least one night. This method can effectively remove suspended solids in wastewater, flotation agents and heavy metals content is decreased. The longer the residence time, the better the treatment. The overflow water in the tailings pond can be recycled. Re-election, magnetic separation and simple flotation of a single metal ore have low water quality requirements, water recycling rate of up to 80%, or no drainage at all. When the tailings particles are extremely fine and partially colloidal, a coagulant can be added to the tailings water to accelerate the clarification process and improve the treatment effect. If lime is added to the tailings water, 60-70% of the xanthate and black medicine can be removed. If the supernatant of the tailings pond does not meet the discharge standards, it should be further processed. Commonly used treatment methods are: 1 removal of heavy metals by lime neutralization and roast dolomite adsorption. To remove 1 mg of copper, 0.81 mg of lime is needed, 1 mg of nickel requires 0.88 mg of lime, and the pH requirement is controlled to be 8.5 or more. Copper and lead ions can be removed by adsorption of calcined dolomite having a particle size of less than 0.1 mm. Removal of 1 mg of copper requires 25 mg of dolomite, and 1 mg of lead requires dolomite 2.5 mg. â‘¡ removing ore by flotation adsorption, organic lead zinc ore flotation agent can be adsorbed to remove the 1 mg for an organic lead-zinc ore flotation agent 200 mg. Treatment with activated carbon adsorption is more effective, but expensive. Cyanide Wastewater â‘¢ major chemical oxidation, such as oxidation bleach; ferrous sulfate can also be used in addition to lime method and the method of lead-zinc ore cyanide, cyanide was added 200 g per gram of ore, simple cyanide may be removed about 90%, or complex cyanide The compound is about 70%. High concentration of cyanide-containing wastewater can recover sodium cyanide Anti-overflow Emergency Absorbent Kits Suitable for cleaning, oil and chemical leakage areas, 30L-240L absorb volume Wuxi Huanawell Metal Manufacturing Co., Ltd. , https://www.wxhnwmetal.com
