operations required before the iron ore is considered a finished product include: • Crushing Screening • Grinding • Concentration • Agglomeration Crushing and Screening Following blasting, the fragmented ore is loaded on a mining truck and hauled to the crusher for primary crushing.
It has been estimated that grinding consumes up to 4% of global electrical energy and accounts for more than 50% of the total energy used in mining operations. In addition, more than 90% of the total energy supplied in beneficiation plants is dissipated as heat, kinetic energy, noise, and inefficient breakage of ores/raw material.
Geology, deposit types, and ore minerals. There are more than 200 minerals that contain REE. 7,8 The most common rareearth minerals are monazite and bastnäsite (Figure 1ab and Table II).Monazite exists as a group of arsenates, phosphates, and silicates, but the primary REEbearing monazite is a complex phosphate. 5 Bastnäsite, also known as bastnaesite and bastnasite, is a fluorocarbonate.

Concentration methods are employed to remove worthless gangue material and concentrate the valuable minerals of the crude ore in a smaller bulk.
This process starts with the crushing of spodumene ore. The cause behind the grinding of the spodumene is an acceleration of the heat transfer between the surrounding atmosphere and the mineral. The crushed mineral is then heated in a furnace at, at least, 1000 °C for 30 min. It is stated that almost any kind of furnace will do for this part ...
