Selective comminution and an understanding of the interactions with a subsequent separation step are essential for recovering valuable components from slags that are present in small quantities. Wet comminution has advantages when it comes to further wet processing such as flotation or density separation, higher finenesses and thus degrees of decomposition can be produced and solubilities can be influenced by additives. Based on findings from the selective comminution of two-component mixtures and ores, it is postulated here that different fracture behaviors of the individual components enable selective comminution through specific selection of the stress conditions. This is to be investigated and understood in detail for wet comminution. The starting point for the investigations are three mineral phases frequently occurring in a lithium slag, which are first processed as individual materials, then as mixtures and finally as artificial slag. The aim is to apply the fracture behavior determined from the single-substance comminutions to first mixtures and then slags in order to specifically set suitable selectively acting stress conditions. Consideration of the subsequent separation and also the effect of certain additives is also planned.

选择性粉碎和理解与后续分离步骤的相互作用对于从少量存在的炉渣中回收有价值的组分至关重要。湿法粉碎在进一步的湿法加工如浮选或密度分离方面具有优势，可以产生更高的细度和分解程度，并且溶解度可以受到添加剂的影响。基于从双组分混合物和矿石的选择性粉碎的研究结果，这里假设，各个组分的不同断裂行为使得能够通过特定选择的应力条件进行选择性粉碎。这一点在湿法粉碎中需要详细研究和理解。研究的出发点是锂渣中经常出现的三种矿物相，它们首先作为单独的材料处理，然后作为混合物处理，最后作为人造渣处理。目的是将由单一物质粉碎确定的断裂行为首先应用于混合物，然后应用于炉渣，以便具体地设置合适的选择性作用的应力条件。还计划考虑随后的分离以及某些添加剂的影响。
