在采矿和冶金工业中，固液分离是几乎每一个工艺的基本组成部分。在运到冶炼厂以前，产品的脱水是选矿工艺中的最后工序。浸取渣的分离和洗涤也是许多冶金过程的一个重要部分。在这些工业的众多部门中，脱水效率的提高能导致能耗、操作费用和废水处理成本的降低。这在许多情况下，通过用压滤机替代现行脱水设备能获得成功。 In the mining and metallurgical industries, solid-liquid separation is an essential part of almost every process. Prior to shipment to the smelter, product dehydration is the last step in the beneficiation process. Leaching residue separation and washing is also an important part of many metallurgical processes. In many sectors of these industries, increased dewatering efficiency can result in lower energy costs, operating costs, and wastewater treatment costs. In many cases, this is successful by replacing existing de-watering equipment with filter presses.
