The froth is separated and dried. So, the oil used as a frothing agent in the Froth flotation process is pine oil. Therefore option (D) pine oil is correct. Note: Froth floatation is mainly used for sulphide ores. Froth flotation separates the gangue from the ore but this method can also be used to separate the two sulphide ores.
Solution. Verified by Toppr. Pine oil is added in the froth flotation method to create froth or bubble so that metal can be purified easily because pine oil prevents the ore from gangue for further mixing. Pine oil also acts as the best substance for forming froth for the minerals. It also increases the non-wettability of mineral particles.

The froth flotation process is typically used for treating <0.5-mm size coal and is currently the only technique both effective and economical to clean coal on a commercial scale. In the USA, the majority of coal preparation plants discard the <0.5-mm coal owing to the high cost of processing of the fine coal.
Answer: In the froth flotation process, pine oil acts as a frothing agent, helping in the creation and stabilization of froth. It reduces the surface tension of the pulp, making air bubbles stable and more persistent, which enables the successful separation of desired minerals from unwanted gangue particles. The steps involved in the process ...

The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10].

Pine oil is a frother in froth flotation. It is added to the flotation cell to produce a stable layer on the surface of the slurry. The layer is important because it provides a means of collecting the target mineral particles and separating them from the rest of …
(4) Pine oil is used in Froth floatation. Ans. Froth flotation is a process to purify sulphide ores, in presence of pine oil. The oil acts as a hydrophobic agent and forms froth with hydrophobic impurities which is skimmed off from the surface leaving behind the concentrated mineral.

Solution. Froth flotation is a process to purify sulfide ores, in presence of pine oil. The oil acts as hydrophobic agent and forms froth with hydrophobic impurities (gangue) which is skimmed off from the surface leaving behind the concentrated mineral. Wet pine oil is used in froth flotation process because it does not have an affinity towards ...
So, pine oil is used in froth floatation methods to purify sulfide ores to remove the dirt leaving behind the cleaned ores. Note: We should know why pine oil is hydrophobic in nature. Pine oil is an essential oil obtained by the steam distillation of needles, twigs and cones from a variety of species of pine. Chemically, pine oil consists ...

Froth stability is a critical factor for flotation and even a small decrease in froth stability causes a decrease in the recovery of desirable minerals (Hadler and Cilliers, 2009, ... with or without an additional collector), pine oil is widely used in the flotation of zinc and iron (Deng et al., 2017, Ilkhechi et al., 2017, ...
For successful exploitation of differences in surface properties most ore minerals must be ground finer than 48–65 mesh. A light mineral such as coal (density circa 1.4) can be floated at 10 mesh, provided the bubble system on which it is borne is developed as a quiet layer of froth. Random changes of direction, acceleration, and collision ...
