Mining chemicals can be broadly classified into several categories, including collectors, frothers, depressants, and flocculants. Each type serves a distinct purpose that is crucial to the overall mining process. Collectors, for example, are used in flotation processes to help separate valuable minerals from ore by making them hydrophobic. This property allows the minerals to attach to air bubbles, rising to the surface where they can be collected as a concentrate. Frothers aid in stabilizing the froth formed during flotation, while depressants are used to selectively inhibit certain minerals from floating, ensuring a higher purity of the desired product.
