No. 12613.—14th May, 1900.—FREDERICK JOHN CORBETT, of 11, Portland Place, South Yarra, Victoria, Gentleman. An improved process for manufacturing lead-carbonate, PbCO or 2PbCO₃+PbH₂O₂ (white-lead).

Claims.—(1.) The process of manufacturing lead-carbonate, PbCO₃ or 2PbCO₃+PbH₂O₂ (white-lead), by dissolving lead Pb or lead-oxide Pbo (litharge) in a solution of aldehyde C₂H₄O acidulated, or aldehyde C₂H₄O and water H₂O acidulated with any suitable acid, and the precipitation of same by carbonic-acid gas CO₂ or liquid carbonic-acid CO₂ under pressure in an airtight vessel or vessels in which the contents are agitated in any suitable manner, and which on discharge are treated substantially as described.
