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%.

The fineness of the ore particles produced by grinding is crucial to recover the minerals by flotation. The most common grinding machines are semi-automatic (SAG) and automatic (AG) mills and ball mills. Grinding size Determining an optimal grinding size can maximize the recovery of target minerals in the subsequent flotation process.
