Abstract
La invención se relaciona con un proceso y sus plantas relacionadas para la reciclaje de residuos de óxido de zinc. Por consiguiente, los residuos de óxido de zinc son granulados en partículas de un tamaño de d80 entre 0,3 y 5 mm, de preferencia entre 0,5 y 2 mm. Estas partículas se alimentan a un horno de calcinación en que se someten a tratamiento térmico a una temperatura en el rango de 500 a 1200 °C, de preferencia 800 a 1100 °C, en un lecho fluidizado para así obtener un calcinado. Los residuos de óxido de zinc se componen de polvo de óxido de zinc cuyas partículas tienen un tamaño d80 menor que 100 um de preferencia d80 menor que 75 um, y y provienen de calderas, hornos sumergidos, hornos de reducción férrica, procesos de galvanización y/o reciclaje, específicamente reciclaje de acero, cobre, plomo, níquel y/o chatarra electrónica, y/o en que los residuos de óxido de zinc provienen de la fundición de plomo y zinc, cenizas y/o espumas de un proceso de Zamak, ceniza de óxido de zinc, catalizadores, fusión y vaciado de Zn y/o escoria de zinc.The invention relates to a process and related plants for recycling zinc oxide waste. Accordingly, zinc oxide waste is granulated into particles of a d80 size between 0.3 and 5 mm, preferably between 0.5 and 2 mm. These particles are fed into a calcining furnace where they are subjected to heat treatment at a temperature in the range of 500 to 1200 °C, preferably 800 to 1100 °C, in a fluidized bed to thereby obtain a calcined product. Zinc oxide waste consists of zinc oxide powder whose particles have a d80 size less than 100 um, preferably d80 less than 75 um, and come from boilers, submerged furnaces, ferric reduction furnaces, galvanization and/or recycling processes, specifically recycling of steel, copper, lead, nickel and/or electronic scrap, and/or where the zinc oxide waste comes from lead and zinc smelting, ashes and/or foams from a Zamak process, zinc oxide ash, catalysts, Zn melting and pouring and/or zinc slag.
