Abstract

PROCEDIMIENTO DE REDUCCION DE MINERALES DESMENUZABLES EN PARTICULAS. CONSTA DE LAS SIGUIENTES OPERACIONES: 1. ESTABLECER Y MANTENER UNA ZONA DE REDUCCION EN LA PARTE SUPERIOR DEL LECHO DE UN REACTOR DE EJE VERTICAL; EN LA PARTE INFERIOR SE ESTABLECE UNA ZONA DE ENFRIAMIENTO DE LAS PARTICULAS REDUCIDAS. 2. INTRODUCIR UN GAS REDUCTOR CALIENTE HACIENDO QUE CIRCULE A TRAVES DEL MINERAL DESMENUZADO. 3. ELIMINAR EL GAS REDUCTOR. 4. CIRCULACION DE UN GAS DE ENFRIAMIENTO QUE CONTIENE CARBONO. 5. INCORPORAR UN GAS DE COMPENSACION QUE CONTIENE CARBONO REGULANDO DE MANERA DIFINITIVA LA PROPORCION EN QUE SE INCORPORE EL GAS DE COMPENSACION. EL GAS RETIRADO DEL CIRCUITO DE ENFRIAMIENTO SE CALIENTA. Y SE COMBINA CON EL GAS REDUCTOR QUE SE INTRODUCE. EL GAS QUE ESCAPA DEL CIRCUITO DE ENFRIAMIENTO DE DESAHOGA DEL CONDUCTO EXTERIOR DESUES DE HABERSE ENFRIADO.
