摘　　要：以内蒙古某多金属矿选矿厂为例,针对严寒天气对选矿的影响,详细介绍了多项适应严寒地区气候特点的节能措施,如多作业共厂房集中布置、设置良好的建筑朝向、采用半自磨工艺、高频细筛与球磨机形成闭路分级、摇床多层立体布置、选用耐磨管道、管道防冻、采用厂前回水和降低采暖温度梯度等,为严寒地区和寒冷地区建设选矿厂提供借鉴。Taking a polymetallic ore concentration plant in Inner Mongolia as an example,aiming at the influence of severe cold weather on beneficiation,this paper introduced in detail a number of energy-sav-ing measures to adapt to the climatic characteristics of severe cold region,such as centralized layout of multi-work workshops,good building orientation,SAB process,closed-circuit classification formed by high frequency fine screen and ball mill,multi-layer layout of shaking table,selection of wear-resistant pipe,pipeline anti-freezing,adopting water returning near concentrator,and reducing heating tempera-ture gradient.The energy-saving measures provided reference for construction of concentrator in severe cold region and cold region.
