One of the factors affecting the quality and performance of the building stone polishing process is the quality of water used. Generally, water used in stone processing plants is constantly being recycled and reused, so it always contains suspended particles. These suspended particles can have detrimental effects on the surface quality of processed rock. Flocculant is one of the most common uses in industry, which leads to the deposition of suspended particles and improves water quality. In this study, the effect of concentration of two types of flocculants (anionic and cationic) on the performance of the polishing process has been investigated. For this purpose, two common building stones including granite (Natanz black) and marble (Lashter) were tested for polishing and the effect of flocculants on the roughness and gloss of the rock surface after polishing and abrasion of polishing pieces was eva‎luated. Studies have shown that in general, increasing the concentration of flocculants leads to increased polishing performance and reduced costs (bite consumption). The results also showed that the use of cationic flocculant for granite (Natanz black) and the use of anionic flocculant for marble (Lashter) has better results.
