An overview of kaolin and its potential application in …
Primary kaolin deposits are formed when kaolinite-rich rocks undergo weathering and alteration. This process breaks down the rocks into smaller pieces, which are then carried away by wind or water. Secondary kaolin deposits are formed when the pre-existing kaolin deposits are reworked by alteration or other geological processes.

Abstract Secondary kaolins in Upper Devonian deposits are developed within the tectonic depression in the south of the Voronezh Anteclise. They formed as a result of erosion of the weathering crust developed on Precambrian crystalline rocks. With this, the Mamon sand–kaolin stratum (SKS), in which kaolins are interbedded with …

Secondary operations of plastics | Technology by Covestro
Machining refers to a variety of subtractive processes in which a cutting tool removes unwanted material from a part to produce the desired shape. Machining plastic parts may be cost-prohibitive in high-volume manufacturing, but is commonly used as a secondary process where material removal is minimal and cycle times are short.
