In the process presented in this paper, it will be shown, in contrast with the above quotation, that there will be no need for the addition of any external alkali, in order to extract ferric iron into the organic phase. The process makes use of the alkaline property of the calcine material itself by starting the process with organic leaching, i.e. leaching zinc oxide with the organic carboxylic acid RH.

Steel making the basic oxygen process. Impurities in the iron from the Blast Furnace include carbon, sulphur, phosphorus and silicon. These have to be removed. Removal of sulphur. Sulphur has to be removed first in a separate process. Magnesium powder is blown through the molten iron and the sulphur reacts with it to form magnesium sulphide. This forms a slag on top of the iron and can be removed.
