Abstract: Process for the continuous production of carbon monoxide and hydrogen as separate products utilizing as raw materials water and carbon, such as coal, char, coke and other carbonaceous materials. Hydrogen is produced by oxidation of phosphorus with steam in the first step of the process. The resulting phosphorus oxides are reduced with carbon in the second step of the process to produce carbon monoxide and elemental phosphorus which latter is recycled to the first step. Essentially no phosphorus is consumed.

Abstract: A process is disclosed for recovering copper from an aqueous solution containing a copper salt, as well as other metal salts, which comprises contacting the aqueous solution with a waterimmiscible organic solution containing a hydroxy-oxime selective extractant for copper, and thereafter stripping the copper from the organic solution. In this particular process, the speed of extraction, the breadth of the pH range for extraction, the Cu/Fe ratio and the efficiency in stripping the copper from the organic solution are all improved considerably by having a small amount of a sulfo compound, preferably a dialkyl sulfosuccinate, present in the organic solution. The copper is recovered in a form suitable for electrolytic deposition of metallic copper.
