MultiDimFlot - efficient multidimensional ultrafine particle separation using a mechanical flotation cell combined with froth fractionation

MultiDimFlot代表一项旨在通过转子-定子槽中的强化机械浮选和深层泡沫中的分馏相结合来高效多维分离超细颗粒（x < 10 µm）的技术开发，作为为期六年的优先计划DFG SPP 2045 MehrDimPart的一部分。分离是指多维的（基于各种分离参数），通常是协同的，通常是统计分布的颗粒性质：尺寸，形状（包括粗糙度）和表面能（包括表面组成）。主要目标是：（i）扩大传统浮选工艺的范围（10 µm < x < 200 µm）对超细颗粒，在原材料和回收分支内建立可持续的价值链，避免处理矿泥，同时（ii）通过深入了解微观尺度和用途，实现高效的多维分离技术（iii）井的技术转让-MultiDimFlot的应用目标是开发基于几种甚至组合的颗粒特性（尺寸、形状、粗糙度和表面能（润湿性））分离超细颗粒的处理技术概念。该概念基于泡沫浮选，结合了机械槽中高碰撞率的优势和基于超细粉浮选最新知识的深度水洗泡沫的分馏特性。该技术也适用于从资源工业到一般化学工业的广泛应用范围的大量材料。通过对微观尺度的研究以及对颗粒和工艺性能关系的研究，设想在化学工程界特别是界面工程和颗粒技术中遵循高影响力研究结果的科学目标。它被认为有助于提高对超细粉体行为的理解，为新型，高效和可持续的工艺开辟道路。让MultiDimFlot成为DFG SPP 2045优先计划的一部分，旨在通过讨论和联合使用研究基础设施，通过强大的网络能力，从一组研究人员之间的知识转移中获益。

MultiDimFlot stands for the development of a technology aiming for the efficient multidimensional separation of ultrafine particles (x < 10 µm) by a combination of intensive mechanical flotation in a rotor-stator cell and fractionation in a deep froth, as part of a total of six years lasting priority program DFG SPP2045 MehrDimPart. The separation is meant to be multidimensional (based on various separation parameters) with respect to the following, often synergistic and usually statistically distributed particle properties: size, shape (including roughness) and surface energy (including surface compositions). The main aims are: (i) expand the limits of conventional flotation processes (10 µm < x < 200 µm) towards ultrafine particles, for a sustainable value chain within the raw materials and recycling branch avoiding disposal of slimes and at the same time (ii) enabling the efficient multidimensional separation technology through an in depth understanding on the microscale and usage for (iii) the technology transfer of the well-known method from the raw materials industry to the German and European based chemical industry of the production and processing of ultrafine particles.MultiDimFlot has as an applicative goal the development of the processing technology concept of separating ultrafine particles based on several, even combined particle properties: size, shape, roughness and surface energy (wettability). The concept is based on froth flotation bringing together the advantageousness of high collision rates with in a mechanical cell and the fractionating properties of a deep, water-washed froth based on the latest in knowledge on the flotation of ultra-fines. The technology shall be valid also for larger amount of material for a broad application range from resource industries to the general chemical industry. By through investigations on the micro scale and investigations on particle and process property relations it is envisaged to follow the scientific goal of high impact findings within the chemical engineering community especially for interface engineering and particle technologies. It is thought to serve the improved understanding of the behavior of ultra-fines in general, opening up the path to novel, efficient and sustainable processes. Having MultiDimFlot be part of the DFG SPP2045 priority program aims to profit from the improved transfer of knowledge amongst a group researchers by strong networking capabilities, through discussions and joint usage of research infrastructure.
