Which of the following ores is most suitably concentrated by the froth flotation process?

1. Galena
2. Malachite
3. Magnetite
4. Siderite

Correct answer: Galena

Solution

Galena, which is primarily composed of lead sulfide, is effectively concentrated using the froth flotation process due to its hydrophobic properties, allowing it to separate from other minerals in an aqueous solution.
