摘要： It is possible to produce battery grade metallic lithium from naturally occurring or industrial brine by a process comprising the following steps: (i) precipitating magnesium with calcium hydroxide; (ii) removal of boron via extraction of solvents; (iii) precipitation of lithium with sodium carbonate; (iv) transformation of lithium carbonate to bicarbonate of lithium with carbonic acid; (v) decomposition of bicarbonate of lithium into high purity lithium carbonate as a result of heating of the solution.Re-precipitation of lithium carbonate by the formation of bicarbonate of lithium allows for the removal of the majority of contaminants which co-purify with lithium carbonate and yield battery grade highly purified lithium carbonate.

摘要： In a method of extracting lithium from a lithium bearing mineral, the mineral is reacted with a basic material of sufficient strength to dissolve the mineral, in order to produce a product mixture containing lithium. The lithium is then recovered from the product mixture. A method of extracting lithium from a lithium bearing mineral may consist of a two-step process. An industrial scale method of extracting lithium from a lithium bearing mineral can be conducted at a temperature not greater than about 500° C. and without the production of sulfur. A lithium metal can be produced by the method.

C., under a pressure of from 15 to 65 bar and at a suspension density between 8 and 18% by weight for from 0.5 to 3 hours; filtering the suspension to remove insoluble solids and to form a digestion filtrate; adding at least one acid or acid anhydride to the digestion filtrate to adjust its pH to 6 and to form the cesium and rubidium salt-containing solution; and performing an evaporation after the hydrothermal digestion to obtain an increase in concentration of cesium salts and rubidium salts in the cesium and rubidium salt-containing solution and to adjust a density of the cesium and rubidium salt-containing solution to from 1.6 to 3.3 g/cm.sup.3. An optional aeration of the digestion filtrate with carbon dioxide to remove lithium and calcium ions in precipitated carbonates may be performed.
