2004年秋季,一家专门用于处理矿物废料的土壤清洗厂在瑞士的雷根施陶夫(Regensdorf)地区投入使用。工厂的设计处理能力为6万t/a,并配备了几台高效擦洗机。初步的操作指标证实,这一工序能很好地适用于清洗尾砂组分。通过清洗土壤回收的砂料和砾石产品,已被用作再回收的高质量建筑材料。工厂的经营者是瑞士Boden资源再回收公司,一家于2004年4月在雷根施陶夫地区成立的公司。这也是第一家配备着德国阿姆贝格高岭土公司(Amberger Kaolin-werke GMBH)的专利高效擦洗机的土壤清洗工厂。
In the autumn of 2004, a soil cleaning plant dedicated to the treatment of mineral waste was commissioned in the Regensdorf region of Switzerland. The plant has a design capacity of 60,000 t / a and is equipped with several high-efficiency scrubbers. Preliminary operational indicators confirm that this procedure is well suited for cleaning tailings components. Sand and gravel products recovered by soil washing have been used as high quality building materials for recycling. The plant is run by Boden Resource Recycling, a Swiss company founded in Regenschutz in April 2004. This is also the first soil cleaning plant to be equipped with a patented high-efficiency scrubber at Amberger Kaolin-werke GMBH.
