发明名称 Processo e dispositivo para a recuperação de materiais de valor
摘要 <p>The invention relates to a process for recovery of valuable material by reduction of oxygen-bonded metals in metallurgical vessels, and a melt furnace plant having a partition projecting into the vessel from the furnace ceiling dividing the furnace into two parts, having a device for supplying thermal (heat) energy, material feed and melt discharge apparatuses and a connection to a gas purification unit, for carrying out the process. The process is characterised according to the invention in that a solid or liquid charge in the first reaction zone is subjected to thermal energy until, in the case of a solid charge, a melt bath forms, or in the case of a liquid charge a melt bath is maintained, in which liquid slag floats on a metallic melt bath, in that the melt bath is fed to a second reaction zone in which the slag comes into intimate contact with a reducing agent, and in that thermal energy preventing solidification is additionally supplied to the melt in the reduction zone. <IMAGE></p>
