Autogenous and Semi-Autogenous Mills - ScienceDirect

The AG/SAG mills generally receive ore directly from the crushing plants with alternative arrangements made to receive ore from a stockpile. In rare cases, the feed is directly from the mine. Schematic diagrams of a typical semi-autogenous mill with large D/L ratio and a square mill are illustrated in Figure 9.1, Figure 9.2.

To a more significant degree than in other comminution devices, SAG Mill Liner Design and Configuration can have a substantial effect mill performance. In general terms, lifter spacing and angle, grate open area and aperture size, and pulp lifter design and capacity must be considered.

Geometallurgy - Wikipedia

Geometallurgy relates to the practice of combining geology or geostatistics with metallurgy, or, more specifically, extractive metallurgy, to create a spatially or geologically based predictive model for mineral processing plants. It is used in the hard rock mining industry for risk management and mitigation during mineral processing plant design.
