According to the "gold" magazine in 2003 fifth entitled: "A gold smelter cyanide waste water" zero emissions "production practice" describes an article in a Gold Smelter through the transformation of the washing process, to achieve a cyanide-containing wastewater “Zero emission. Through the adoption of new equipment, new process and other measures to achieve full circulation of various sewage, reduce the discharge of cyanide wastewater. Through the production practice of the plant, it is proved that the “zero emission†of sewage is an effective way of environmental protection.
Because cyanide leaching technology mature and stable, at home and abroad will continue to cyanide gold industry as the preferred agent is selected from gold, making gold processing plant for disposal of waste water containing cyanide has become the subject studied.
A gold smelter adopts 200t/d expansion of sulfur gold mine and the treatment scale reaches 340t/d. The wastewater discharged from the production of the plant has 821.7m 3 /d of waste acid. Production plant effluent discharge has spent acid obtained 220m 3 / d, the acid waste water 477.2m 3 / d, cyanide waste water 821.7m 3 / d, the discharge amount of water per day to a tailings dam 1439m 3 / d, sewage treatment fee 220 Ten thousand yuan / year. In order to improve the utilization of resources, reduce the pressure of tailings dams, and reduce the cost of sewage treatment, the plant reformed the washing process in 1999, and explored and tried to achieve zero discharge of wastewater, so that the entire process is closed with water after the transformation. The circulation, the amount of sewage discharged to the tailings pond is zero, the sewage treatment cost is reduced by 724,700 yuan/year, and the annual creation benefit is 1,727,400 yuan. The economic benefits and environmental and environmental benefits are remarkable.
