发明名称 Stable ferric arsenate precipitation from acid copper solutions whilst minimising copper losses
摘要 A method of which includes the steps of introducing an acidic solution containing (V), copper, ferric iron and ferrous iron into a first tank of a series of continuously stirred tank reactors and, in the first tank, adding air to the solution; heating the solution to an elevated temperature; recycling a portion of selectively precipitated ferric arsenate compounds to the said first tank; and seeding the solution with ferric arsenate compounds.
