11.27 Feldspar Processing
Conventional open-pit mining methods including removal of overburden, drilling and blasting, loading, and transport by trucks are used to mine ores containing feldspar. A froth flotation process is used for most feldspar ore beneficiation. Figure 11.27-1 shows a process flow diagram of the flotation process.

Open Pit Mining
8.2.3.1 Open pit mining. Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.

An overview of sampling best practice in African mining
RC drilling is the preferred primary sampling method in open-pit mining operations. Once the broken RC drill cuttings are recovered, several methods of secondary sampling are used. RC rigs are usually accompanied by a cyclone ( Figure 3a ) which is used to collect the borehole cuttings, usually at 1 m intervals.

Exploring digital twin systems in mining operations: A review
Autonomous production drilling systems, together with autonomous trucks, are perhaps the closest to a full digital twin system in mining operations, particularly in open-pit environments. Even if an operator is involved in a remote operation, if the drills are fully autonomous, the operator's role is mainly for monitoring purposes.
