Without reagents there would be no flotation, and without flotation the mining industry, as we know it today, would not exist. Reagents in mineral processing are therefore an inseparable part of the flotation process. Many books, articles and patents exist on development of reagents, reagent chemistry and reagent application. In spite of all this, researchers and those who work on the development of reagent schemes for the treatment of new ores or improvement in existing operations still rely heavily and almost exclusively on the advise of chemical companies and their technical services to select specific collectors or depressants for the plant. Unfortunately, the reagent schemes do not consist of only collectors and frothers. Pulp chemistry in an operating plant is a complex system involving the interaction of all additives, including collectors, depressants, activators, pH regulators, frothers and, most of all, soluble components of the ore and altered mineral surfaces. <...>
