2 An ore is that mineral in which a particular metal occurs in some significant amount and can be extracted economically Some common examples of iron ore are hematite and limonite etc Extraction of iron The extraction of iron is mainly from its oxide hematite and the process of extraction of iron involves the following steps Concentration
An effective method for directly extracting lithium from Thus lithium extraction from ore has a more effective utilization value [18] limestone roasting [19] [20] chlorination roasting [21] [22] [23] sulfate roasting [24] [25] and alkali autoclaving methods [26] Among them the earliest method is the limestone roasting method
The raw materials used in the extraction of iron are iron ore coke made from coal and limestone Iron ore is the primary source of iron while coke is used as a reducing agent and fuel and
lime or limestone are inexpensive and easy to obtain and no other reagents are needed However excess CaO eventu ally enters the leaching residues producing a large volume of solid waste Meanwhile the extraction yield of lithium is rel atively low compared with other methods The lime roasting
Calcium metallurgy is a metallurgical technology of extracting metallic calcium from calcium containing minerals In 1808 British chemist H David mixed wet quicklime and mercury oxide at a ratio of 3 1 by weight and then electrolyzed to obtain calcium mercury alloy Anhydrous calcium chloride is obtained from limestone ore by hydrochloric
