    Bagration states that the solution of metallic gold in cyanide of potassium is facilitated by a rising temperature. Little attention was paid to this point in the early days of the cyanide process, but in 1899 Loewy stated that experiments at the May Consolidated Gold Mine in 1893 yielded 10 to 14 per cent higher extraction when heat was applied.
