It can be used to compare different reagent conditions in the same cell, or different flotation cells treating the same pulp. Each particle type in an ore (e.g., chalcopyrite, pyrite, pyrrhotite and quartz) will have its own value of k in any test, and the ratios of these values are a quantitative measure of the selectivity of the operation.

Froth Flotation Process - Mineral Processing & Metallurgy

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.

Reagent - Wikipedia

A reagent / r i ˈ eɪ dʒ ən t / is a substance or compound added to a system to cause a chemical reaction, or added to test if a reaction occurs. The terms reactant and reagent are often used interchangeably—however, a reactant is more specifically a substance consumed in the course of a chemical reaction. Solvents, though involved in the reaction, are usually not called reactants.
