ABSTRACT:
The invention relates to the treatment of a liquid with a gas. A gas injector, for example oxygen, is surrounded with a sheath to carry a flow of a liquid under treatment (for example lead) which is taken up and circulated by the pump. The end of the injector is thereby protected by moving away the bubbles of oxygen. Application for example in the refining of metals, for example non ferrous metals, food liquids, paper pulps and the production of sulfur.
