高寒高纬度地区尾矿膏体生产排放实践

THE PRACTICE OF TAILINGS PASTE DISCHARGING TECHNOLOGY IN HIGH AND COLD REGION

在我国大型选矿厂中首次应用世界上最大的深锥膏体浓密机,实现尾矿膏体排放。在极端温度-47℃的严寒地区,创造了夏天尾矿库内基本没有水,冬季尾矿排放不冻结,在大风肆虐的天气干尾矿基本不扬尘的操作方法。对尾矿库安全和环境保护十分有利,经济效益显著。

For the first time in China,the world＇s largest deep cone paste thickener is put in use at an extreme temperature of-47 degrees in the cold area,creating a basictailing-paste pond with little water content in summer,discharging tailings without freezing in winter,no dust generation in windy days. The application of this thickener is very favorable for safety and environmental protection of the tailings pond and has significant economic benefits.
