如何降低选矿成本？知乎

选矿成本主要包括原料成本、设备成本、场地投资、人工费用等。其中占主要费用的是设备成本。设备是我们选矿领域的重中之重，它决定了我们的产品质量和经济收益。选矿设备主要包括：破碎机、制砂机、磨粉机、筛分设备、输送设备、磁选机、浮选机等。这里的矿物加工领域中破碎、磨矿能耗约占选矿工艺总能耗的40% ~60%, 大型选矿厂用于碎磨作业的成本通常占选矿总成本的50% 以上,世界能源的10% 以上都消耗在破碎和磨矿作业中矿山碎磨设备节能降耗现状及发展趋势矿山系统工程研究所干选只适应于破碎产品预选抛废石、缺水地区选矿，成本要看选矿流程及磨矿否，如果是破碎产品预选抛废，铁矿石加工铁精粉干选成本5~10元/吨；干选的优点是产品无需脱水；缺点是选矿效率差，难以得到纯度较高的产铁矿石加工铁精粉的方法与成本知乎知乎专栏
