摘要： The invention relates to a method for purifying impure lithium bicarbonate by means of a cation exchange resin. In addition to solution purification by ion exchange, the treatment stages include the regeneration of impurity metals bound to the resin. Regeneration consists of washing the resin with water, elution with acid solution, washing with water, neutralisation with alkali solution and washing with water. It is characteristic of the method that neutralisation is performed with sodium hydroxide solution.

摘要： A method and arrangement for recovering lithium carbonate from a raw material containing lithium, which method comprises pulping (1) the raw material containing lithium in the presence of water and sodium carbonate for producing a slurry containing lithium from the raw material containing lithium. After pulping the lithium-containing slurry is leached (2) for dissolving the lithium in the solution thus producing a solution containing lithium carbonate. After pulping and leaching the method comprises carbonating (3) the solution containing lithium carbonate by using carbon dioxide under atmospheric conditions for producing a solution containing lithium bicarbonate and separating (4) the solids form the solution. The solution containing lithium bicarbonate is purified (5) to produce a purified solution containing lithium bicarbonate, and recovering by crystallising (6) lithium carbonate from the purified lithium bicarbonate- containing solution.

摘要： The invention relates to a method for recovering gold in connection with the hydrometallurgical production of copper from a waste or intermediate product containing sulphur and iron that is generated in the leaching of the copper raw material. The recovery of both copper and gold occurs in a chloride environment. The gold contained in the waste or intermediate is leached by means of divalent copper, oxygen and alkali bromide in a solution of copper (II) chloride and alkali chloride, in conditions where the oxygen-reduction potential is a maximum of 650 mV and the pH a minimum of 0.5. The bromide accelerates the dissolution of the gold.
