Question of the Week: What is Reduction Roasting?

Reduction roasting is the removal of oxygen from a component of an ore, usually through the use of Carbon Monoxide (CO). The CO is typically supplied by mixing a carbonaceous material such as coke or coal with the ore, or by feeding it separately. An example is the reduction roasting of a hematite containing material to produce magnetite that ...

Lithium Ore – Spodumene – Alpha Thermal Process

Lithium can be extracted from spodumene concentrates after roasting and acid roasting operations. A concentrate with at least 6% Li 2 O (approximately 75% spodumene) is suitable for roasting. Roasting is performed in rotary kilns at about 1050°C (1922 F), during which spodumene goes through a phase transformation from α-spodumene to β-spodumene.
