dc.description.abstractCoagulation is a process usedto facilitate the agglomeration of particles with the contribution of variousfactors. Although the effects and contributions of many parameters forcoagulation have been reported in the literature, to our knowledge, there arevery few detailed studies on the effects of particle roughness. In this study,the effects of particle roughness obtained with different grinding conditionsand the role of different coagulants such as NaCl, CaCl2, AlCl3, and FeCl3 andtheir contribution to the coagulation of particles were investigated in detail.The results showed that by changing the salt type and major cation type duringthe sedimentation tests, the settling rate values for ball-milled chromitesamples increased from 0.086 cm/s to 0.095 cm/s with NaCl and AlCl3 salts, respectively,while a similar trend but a slightly higher settling rate values varied from0.092 to 0.101 cm/s for rod-milled chromite samples. Accordingly, the sampleswith rougher surfaces, as the rod mill product (2.581 mu m),settled slightly faster than those with the ball mill product (1.920 mu m). From this point of view, it can be suggested that theadjustment of grinding conditions should be taken into consideration during thecoagulation of very fine-sized materials. La coagulation est un proc & eacute;d & eacute; utilis & eacute; pour faciliter l'agglom & eacute;ration des particules gr & acirc;ce & agrave; divers facteurs. Le facteur le plus important qui rend ce proc & eacute;d & eacute; possible est l'interaction des forces qui poussent et attirent les particules ensemble. Par cons & eacute;quent, plusieurs param & egrave;tres tels que le pH, la granulom & eacute;trie, le type et la concentration de coagulant, le temps, etc. peuvent influencer le succ & egrave;s de ce proc & eacute;d & eacute;. Bien que les effets et les contributions de ces param & egrave;tres aient & eacute;t & eacute; rapport & eacute;s dans la litt & eacute;rature, & agrave; notre connaissance, il existe tr & egrave;s peu d'& eacute;tudes d & eacute;taill & eacute;es sur les effets de la rugosit & eacute; des particules. & Agrave; cette fin, dans cette & eacute;tude, on a examin & eacute; en d & eacute;tail les effets de la rugosit & eacute; des particules obtenue par diff & eacute;rentes conditions de broyage et le r & ocirc;le de diff & eacute;rents coagulants, tels que NaCl, CaCl2, AlCl3 et FeCl3 au m & ecirc;me pH d'environ 8, ainsi que leur contribution & agrave; la coagulation des particules. Les r & eacute;sultats ont montr & eacute; qu'en changeant le type de sel et le type de cation majeur pendant les essais de s & eacute;dimentation, les valeurs de taux de s & eacute;dimentation pour les & eacute;chantillons de chromite broy & eacute;s par des boulets ont augment & eacute; de 0.086 cm/s & agrave; 0.095 cm/s avec les sels de NaCl et d'AlCl3, respectivement, tandis qu'une tendance similaire mais avec des valeurs de taux de s & eacute;dimentation l & eacute;g & egrave;rement plus & eacute;lev & eacute;es variait de 0.092 & agrave; 0.101 cm/s pour les & eacute;chantillons de chromite broy & eacute;s par des barres. Cela d & eacute;montre que les valeurs de taux de s & eacute;dimentation sont affect & eacute;es non seulement par la valence et le type de cation majeur, mais & eacute;galement par les valeurs de rugosit & eacute; des & eacute;chantillons. Les & eacute;chantillons avec des surfaces plus rugueuses, comme le produit du broyeur & agrave; barres (2.581 mu m), ont s & eacute;diment & eacute; l & eacute;g & egrave;rement plus rapidement que ceux avec le produit du broyeur & agrave; boulets (1.920 mu m). On peut sugg & eacute;rer que l'on devrait prendre en consid & eacute;ration l'ajustement des conditions de production lors de la coagulation de mat & eacute;riaux de tr & egrave;s petite taille.
