Mineral Flotation | SpringerLink

In the extraction of metals from their ores, the process of mineral flotation plays a most important role. Flotation provides the means of separating and concentrating the valuable components of an ore to produce a grade of mineral concentrate suitable for feeding to efficient pyrometallurgical or hydro-metallurgical operations.

Minerals | Special Issue : Iron Ore Flotation

2021-5-12 · Iron ore flotation is a key technique to concentrate intermediate-low-grade ore, in order to reach the market requirements for higher-grade concentrates of iron. The presence of some impurities in addition to quartz in iron ore, aluminium silicates, and minerals containing phosphorus impair productivity in the steel industry and have an impact on iron ore concentrate value.

MINERAL ORE FLOTATION AID - Behr, David Henry

In a froth flotation process, the ore is subject to comminution, such as by crushing and wet grinding, to reduce particle size of the mineral ore. Additives, such as collectors, frothers, and activators, are added to the ground ore, or pulp, to assist in separating valuable minerals from undesirable gangue portions of the ore in subsequent flotation steps.

2016-4-1 · The flotation of rare earth (RE) minerals (i.e. xenotime, monazite- (Nd), RE carbonate mineral) from an ore consisting mainly of silicate minerals (i.e. primary silicate minerals and nontronite clay) and hematite was investigated using tall oil fatty acids (Aero 704, Sylfat FA2) as collector. The RE minerals are enriched with Fe.
