Befesa Steel :: The SDHL-Waelz Process

At kiln operating temperatures of approx. 1,200°C all volatile elements, mainly zinc, are transformed into the gas-phase and re-oxidized to Waelz oxide. By the off-gas treatment facilities the Waelz oxide is recovered and provided afterwards to the zinc industry as a secondary feed material.

How the rotary kiln works. Rotary kilns are pipes that with a low slope to the horizon, with a slow rotation and due to gravity, direct the material from the inlet of the kiln to the outlet of the kiln. The rotary furnace tubes are mounted on steel rollers and rotate around a horizontal axis with the power and operation of suitable gearboxes.

Producing pure recycling zinc with concentrated solar

First, the zinc oxide from the waste dust is reduced to zinc via a reaction with carbon in a rotary kiln at temperatures of around 1,200 degree Celsius. At these temperatures, zinc is gaseous before being oxidised again through the subsequent reaction with the oxygen present in an injected air stream. The resulting dust-like product is referred to as Waelz oxide. Although raw Waelz oxide is 70

A Brief Summary of Zinc Oxide Processing Methods Available

19/06/2017· further calcination of the zinc oxide produced can occur in a secondary rotary kiln at 1000°C to separate the zinc oxide from other elements increasing the product quality to above 90% ZnO, depending on the lead content. Gases leaving the bag filters are treated to meet environmental regulation standards in terms of dioxins. The un-fumed material (slag) leaves kiln at 1050-1150°C and is
