Abstract

The chapter delves into the crucial initial step of bauxite processing: crushing and grinding. It begins with an introduction to the importance of proper sizing for conveyance and downstream processing. The selection of crushing equipment is discussed, with a focus on the physical characteristics of bauxite and the capacity rates required. Types of crushers evaluated include Jaw Crushers, Cone Crushers, high-speed Impactors, and low-speed Sizers. The chapter also highlights the use of vibrating screens and roller-screens for size separation. Additionally, it explores the use of rotary drum scrubbers for handling sticky bauxite with rock intrusions. The chapter concludes with a discussion on the design requirements and variables for grinding bauxite, emphasizing the variability in grindability among different bauxite types.
