Where the diatomite sequence is thick, benches from 1.5 to 15 m in height are developed. Benching not only facilitates the removal of ore and waste but also permits immediate access to many ore layers and provides the opportunity to blend layers with differing characteristics.

Diatomite, also known as diatomaceous earth, is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder. It is composed of the microscopic remains of diatoms, which are single-celled algae with skeletons made of silica. These skeletons accumulate over time, forming deposits of diatomite.

Keywords: iron ore, grade, gangue, ilmenite I. INTRODUCTION Iron ores are minerals from which metallic iron can be economically extracted [1, 2] The main iron ores are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Magnetite contains 72.4% Fe and usually black while hematite has 70% Fe and red in colour. Other ore include limonite (2 Fe 2 O 3 _3H 2
