Abstract: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-saving 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 temperature gradient. The energy-saving measures provided reference for construction of concentrator in severe cold region and cold region.
