METHOD AND APPARATUS FOR CONCENTRATING NON-FERROUS METALS SUCH AS ANTIMONY AND TIN BY VOLATILIZATION FROM RESPECTIVE ORES OR BYPRODUCTS, AND PROCESS FOR OBTAINING ANTIMONY AND TIN IN THE METAL STATE

摘要

P THE PROCESS DESCRIBED IN THIS INVENTION IS CHARACTERIZED BY THE FACT THAT, IN A SINGLE STAGE, OIL AND OXYGEN AND CARBON COMPOUNDS ARE OBTAINED ALSO WITH COAL OF LESS GOOD QUALITY, VOLATILIZATION OF SULFIDES ETOU OXIDES, WHICH ARE THEN GRILLED IN THE GASEOUS PHASE, BY THE AIR AND BY OXYGEN. AN APPARATUS FOR CARRYING OUT THE PROCESS IS A TRONCONIC SHAPE REACTOR, COMPRISING A METAL ENCLOSURE 2 INTERIORALLY FITTED WITH A REFRACTORY MATERIAL 3, THAT REACTOR THAT CAN ROTATE AROUND ITS VERTICAL AXIS 1, AND IS MUNICINATED AT THE END OF A HOLE FLOW 5, SO THAT THE SOLID PRODUCT THAT IS CHARGED ADHERE UNDER THE EFFECT OF SEVERAL FORCES IN PLAY, TO THE INTERNAL WALLS OF THE REACTOR AND THAT THE LIQUID SUBSTANCES THAT ARE OBTAINED CAN DRAW THROUGH THE FLOW HOLE 5 / P P USE OF THIS METHOD TO OBTAIN ONLY ONE SB OR SN OPERATION IN THE METAL STATE. / P
