Flotation Conditioners -Modifiers -Activators -Depressants

Depressants This is a group of chemicals that react with the minerals to prevent them from floating with the collector. These four are the main classifications of mining reagents that we will deal with. There are others but they either are special use reagents or are used in other processes. These four types of reagents are basic for use in a flotation circuit.
