Direct Extraction | Search Minerals Inc.

The mill feed is finely crushed and treated with relatively small amounts of sulfuric acid in a kiln at 180°C (low temperature) to render the REE water-soluble. After water leaching, the REE solution is purified by neutralizing the remaining acid. The REE are then precipitated into a concentrate using sodium carbonate.

Effects of grinding and dehydration on kaolin in a steam ...

Ultra-fine grinding of the filter cake of kaolin (moisture content 23.80%) was conducted using the steam jet milling system. Dehydration of the ground material was caused by the high-speed superheated steam flow. As a result, the moisture contents of ground products were ~1%, thereby meeting the requirement for moisture content M ≤ 2%.
