[0002] Lithium ore refers to naturally occurring lithium resources that can be mined economically. More than 150 types of lithium minerals and lithium-containing ores have been discovered in nature. The main mineral raw materials for producing lithium are spodumene, lepidolite, pyroxenite, petalite and ferroxenite, among which the first three minerals are the most important. Slag is a molten material with silicate and aluminosilicate as the main components, which is formed by the reaction of impurities such as silicon dioxide and aluminum oxide in iron ore with lime and other substances during the iron-making process in the blast furnace.
