25.3 Crushing and milling | Mining of mineral resources,
Sometimes the rocks (ore) are crushed at the mining site to make them easier to transport. Mining trucks are enormous. They are up to 6 meters tall, that's higher than most houses. These trucks can carry 300 tons of material and their engines have an output 10-20 times more powerful than a car engine.

14.3 Mining and mineral processing | The lithosphere,
Once the ore has been mined it is usually crushed into smaller pieces that can be processed more easily. The mineral then needs to be removed from the ore. Ancient peoples soon learnt that fire could be used to refine and purify the metals. This technique is known as smelting. This was the earliest method used to extract the mineral from the ore.

Ore Is Crushed So That The Mineral Can Be Released
253 Crushing and milling Mining of mineral resources. The ore needs to be crushed, as a choc chip biscuit, to get the minerals out. Once we have crumbled the choc chip biscuit, the chocolate pieces can be separated from the crumbs. In the same way in the mining process the valuable minerals can be separated from the unwanted rock.
Ore Is Crushed So That The Mineral Can Be Released
Ore Is Crushed So That The Mineral Can Be Released Iron processing Ores Britannica Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used. The upgraded

Crusher - Wikipedia
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
