The NP2 reef is the most mineralogically distinctive of the three reef types consisting of the single MCU chromite overlying a predominantly anorthositic footwall. Within the anorthosite there is the development of a troctolite band which marks the downward extent of fluid infiltration from the MCU (Figure 2; Viring & Cowell, 1999).

Frothers. Froth flotation is a process for concentrating minerals from their ores. It selectively separates hydrophobic from hydrophilic materials and is used to recover an array of minerals containing valuable commodities. Quadra offers a wide range of flotation solutions, with the technical expertise to help you optimize your recovery.

Froth Treatment is a process by which water and fine solids are removed from bitumen froth using hydrocarbon-based gravity separation. There are two different types of hydrocarbons used in Froth Treatment: a naphtha-based hydrocarbon and a lighter paraffinic solvent. Both produce a relatively clean bitumen product but only a paraffinic process produces a marketable product stream.

Froth flotation represents the most versatile separation method in mineral processing. It takes advantage of the different surface minerals properties to selectively separate more hydrophobic minerals from less ones towards interactions with air bubbles. Flotation has been initially developed to treat the sulfide minerals of copper, lead, and zinc.

With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.
