Abstract: A froth collection launder for a collection of froth from a mineral flotation includes a first and a second sidewall which are joined to form a bottom including a tip extending along the bottom, the first sidewall including a first end and the second sidewall including a second end at their open ends, at least one of the first and the second ends includes a froth overflow lip, and when the froth collection launder is positioned at its operation position a centre line is located in the middle of the first and the second end in the cross direction (x) of the froth collection launder. The tip is located between the centre line and one of the first and the second end in the cross direction (x) of the froth collection launder and the tip forms the lowest point of the froth collection launder.

Abstract: A froth flotation unit for treating mineral ore particles suspended in slurry includes a tank, a gas supply for introducing flotation gas into the slurry to form froth, and a first froth collection launder including a first froth overflow lip facing towards the centre of the tank. The froth flotation unit has a pulp area of at least 15 m2 measured at a mixing area. The froth flotation unit further includes a second froth collection launder with a first froth overflow lip facing the perimeter of the flotation tank, and a froth blocker arranged between the first froth overflow lip and the second froth overflow lip. A froth flotation line, its use, and a froth flotation method are also disclosed.

Abstract: A stanol composition containing in addition to sitostanol as the main component, also a substantial amount of at least 10% campestanol has been found to effectively lower serum cholesterol levels when incorporated in edible commodities. Upon esterification the composition is especially useful in edible fats and oils and in fat-containing foods.
