Sensor-Based Ore Sorting to Maximise Profit in a Gold

2021. 7. 8.  Sorting requires material to be suitably prepared and presented to the machines and typically this consists of crushing and screening to limit top size and optimise liberation. However, where material streams are suitably sized and prepared, additional equipment may not be required (e.g. the sorting of semi-autogenous grinding (SAG) Mill pebble streams).

As a high Gold recovery is a condition for the economic feasibility of a sensor-based ore sorting installation, it becomes clear why previous COLOR-based gold ore sorting attempts have often failed . The development has led to two pilot installations: one at Björkdals Mine in Sweden [ 81 ], and the other one, in combination with an XRT-baser sorter,

Sensor-based ore sorting to maximise profit in a gold

Sensor-based ore sorting is being increasingly used to reduce the amount of low-grade and waste material processed in mineral concentrators. This type of preconcentration provides bottom-line benefits to users by reducing the amount of energy, water and consumables, as well as reducing capital cost. Existing operations can increase metal production, while previously uneconomic deposits and low
