Mining minerals are generally divided into two, namely metallic minerals and non-metallic minerals. Examples of metallic minerals are iron, copper, tin, molybdenum, aluminum. While examples of non-metallic minerals such as phosphate, marble, bentonite, quartz sand to precious stone minerals, namely diamonds. Non-metallic minerals are widely used for various industrial purposes, one of which is the mineral kaolin. What is the mineral Kaolin?
Definition of Caolin
Kaolin is a rock mass which is then composed of clay material which has a low iron content, and is generally white or slightly whitish in color. Kaolin is a fine white clay mineral excavated from the ground. The mineral content in kaolin is mainly in the form of the mineral kaolinite which is composed of hydrated aluminasilicate. Besides kaolinite, there are also other minerals, namely dickite, nakrite and haloisite. You can get kaolin from kaolin clay supplier Indonesia.
Kaolin Formation Process
Kaolin formation (Kaolinization) can be formed by two geological processes, namely weathering processes and hydrothermal alteration processes.
1. Weathering Process
This process occurs in igneous rocks that contain a lot of feldspar with water triggering media, thus changing the feldspar into kaolin. This weathering process occurs at the surface or very close …
