Question

Define minerals and ores with examples.
What is froth-floatation process for the
concentration of ore?​

Answer 1

Answer:

Froth Flotation Method:

The ore is powdered and a suspension is created in water. To this are added, Collectors and Froth Stabilizers. Collectors (pine oils, fatty acids etc) increase the non-wettability of the metal part of the ore and allows it to form a froth. The oil wets the metal and the water wets the gangue.

Answer 2

Minerals and Ores: Natural materials. The Earth is the main source of minerals and ores. ... Minerals are the natural materials in which the metals and their compounds are found in earth. Ores are those minerals from which metal are extracted conveniently and profitably. These ores contain good percentage of metal.

Froth flotation is a process for selectively separating hydrophobic materials from hydrophobic. In some cases, for example, sulphides ores of copper, zinc and lead concentration is brought by this method.
