The grinding performance was reduced by the addition of Ca 2+ ions when there was a high clay percentage (40%) and a high solid percentage (70%). This paper demonstrated the importance of controlling Ca 2+ concentrations in plant water to maximize the grinding performance of kaolin-containing ores. Previous article.
