The ore is undercut at the top and bottom of the block, providing access for drilling and mucking. Drilling is done by top hammer long-hole drills with holes varying in length between 10 metres and 20 metres long and a hole diameter of 3 inches. Mucking is accomplished by remote LHD units and then loaded to haul trucks.

Introduction: 'Ball milling is a method used to break down the solids to smaller sizes or into a powder. A ball mill is a type of grinder which consists of a cylinder. It is used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. The cylinder rotates around a horizontal axis.

With a growing demand for fine grinding and increases in equipment dimensions, stirred ball mills are becoming an attractive alternative for conventional size reduction equipments in …

The number of discs (grinding stages) depends on the application and can be as high as 20. Feed slurry is pumped into the mill via the bottom connection. When the flow transfers upwards, it passes all consecutive grinding stages. The final product discharges into open atmosphere at the top of the machine.

Hard Rock Mining Tour. Receiving Room - Ore was received at the top of the mill building. Crushing - The raw ore went through several crushers.
