Fluidized bed roasting of micro-pelletized zinc concentrate : Part I-Pellet strength and roasting kinetics

Heukelman, S.; Groot, D.R. (Southern African Institute of Mining and Metallurgy, 2011-11)

Zincor, a zinc refinery in South Africa, uses oxygen enrichment of up to 26% O2 in its fluidizing air to increase concentrate-throughput in its fluidized bed roasters. The aim of the study is to determine whether O2 ...
Fluidized bed roasting of micro-pelletized zinc concentrate : Part II-Particle entrainment and residence time

Heukelman, S.; Groot, D.R. (Southern African Institute of Mining and Metallurgy, 2011-11)

Zincor uses O2 enrichment (up to 26% O2 in the fluidizing air) to increase the processing rate of zinc concentrates in the fluidized bed roasters. The aim of this study is to determine whether O2 enrichment can be reduced ...
