What Are Spodumene Flotation Reagents and How to Choose?

Spodumene ore flotation is currently mainly divided into two processes: reverse flotation cationic collector and positive flotation anionic collector. Common reverse flotation cationic collectors are amine collectors, and the most commonly used is dodecylamine. Such agents can reverse flotation of gangue minerals such as quartz …

Handbook of Flotation Reagents: Chemistry, Theory and Practice

There are several types of mica minerals present in the various types of ore bodies that contain lithium, base metal ore, and other oxide ores. In a number of cases mica has to be removed before flotation of either lithium or other oxide minerals. In the literature it has been quoted that flotation properties of various mica minerals are similar.
