Benzotriazole - Wikipedia
Benzotriazole is an effective corrosion inhibitor for copper and its alloys by preventing undesirable surface reactions. It is known that a passive layer, consisting of a complex between copper and benzotriazole, is formed when copper is immersed in a solution containing benzotriazole.

Benzotriazole - an overview | ScienceDirect Topics
Benzotriazole is a bicyclic nitrogen heterocycle formed by the fusion of the benzene ring with the 4,5-positions or the “ d” site of 1H-1,2,3-triazole.It is also known as 1H-benzo[d]-1,2,3-triazole and exists in two tautomeric 1H- and 2H- forms in which the 1H- form predominates (99.9%) over the 2H- form at room temperature in both gas and solution phases.

Froth flotation - Wikipedia
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Flotation Reagents - Mineral Processing & Metallurgy
Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.
