The minerals contained in natural kaolin are mainly divided into clay and non-clay minerals. Clay minerals: mainly contain kaolinite minerals and a small amount of montmorillonite, mica and chlorite; Non-clay minerals: Mainly contain hydrates of feldspar, quartz and calcium. Iron minerals such as hematite, siderite, limonite, etc., titanium …

Weathered granite contains a high concentration of feldspar, quartz, and kaolin. However, while it becomes rich in clay due to strong physical weathering, the granite minerals that are not fully weathered are still very hard, which makes the grinding process more difficult and limits its use. This study proposes a multi-step process …

1. Introduction. Kaolin is a white-brown powdery clay mineral. It has the main constituent of kaolinite of a hydrous aluminum silicate (Al 2 O 3.2SiO 2.2H 2 O) with a single tetrahedral silicate layer linked via oxygen molecules to a single alumina octahedral layer. The most common auxiliary minerals found with kaolin are maternal rocks such as …
