Abstract

In the extraction of lithium from silicate ores such as petalite, lepidolite and spodumene, the ore is roasted at 300 to 800 DEG C. with a plurality of reactants, (i.e. two or more different reactants), one being a nitrate or hydroxide of an akali metal, preferably sodium nitrate or hydroxide, and the other reactant or reactant being a carbonate, sulphate, oxide or hydroxide or an alkaline earth metal. The roasted ore is then leached with an aqueous medium for the recovery of lithium, the pH of the medium preferably being controlled by the addition of sulphuric acid to a pH of 4 to 7 to extract the lithium as sulphate. The total weight of reactants should be at least equal to the weight of lithia in the ore and may be 10 to 20 times as great, whilst the percentage of the alkali metal nitrate or hydroxide for example may be from 5 to 75 per cent by weight of the total reactants. A mixture of sodium nitrate and sodium hydroxide in the preferred proportion of 1 part hydroxide to 1 to 6 parts of nitrate may be employed. According to examples (1) a spodumene ore was heated to 1130 DEG C. to convert it to b spodumene. The product was ground and mixed with sodium nitrate and sodium carbonate and heated for 1 1/4 hours at 675 DEG C. The roasted material was extracted with an aqueous solution of sulphuric acid at 95 DEG C. and the resulting slurry was filtered and the residue repulped with water. The combined leach liquor and washings at a pH of 6 were treated with calcium hydroxide to a pH of 12 after which sodium carbonate was added to precipitate calcium carbonate. The filtrate was adjusted to pH 8 by sulphuric acid and after reduction in volume by boiling was treated with sodium carbonate to precipitate lithium carbonate. The filtrates and washings may be recycled. (2) b spodumene was mixed with sodium nitrate and sodium carbonate and heated at 675 DEG C. and equal portions of the roasted product were extracted with hot and cold water with and without added sulphuric acid. The percentage extractions are compared. Further examples describe the treatment of spodumene with sodium nitrate and sodium carbonate, sodium nitrate and sodium sulphate, sodium nitrate and sodium hydroxide, sodium hydroxide and sodium carbonate, sodium hydroxide and calcium sulphate, and sodium hydroxide with calcium oxide.
