Question
Chapter 21, Problem 21.5QP
Interpretation Introduction
Interpretation:
The main steps involved in the preparation of ore has to be described.
Concept introduction:
Ore: Ore is naturally occurring solid material from this solid we get metals and valuable minerals profitably.
- Preparation of ore is nothing but the separation of mineral from the naturally occuring ores shuch as crust in the form of silicates.
- These crust and silcate minerals are collectively said to be gangue.
- In preparation of ore the first step invloves dressing of ore, it means finely grinding it as powder. Then this poweder allowed to concentrate, this is called concentration of ore.
