Sensor-based ore sorting is a technology used to classify high-grade mineralized rocks from low-grade waste rocks to reduce operation costs. Many ore-sorting algorithms using color images have been proposed in the past, but only some validate their results using mineral grades or optimize the algorithms to classify rocks in real-time.

The magnet test can identify gold and other associated metals, including iron or placer gold. Pure gold is non-magnetic, but the magnet test can still help identify a specimen and gold alloys. Types of Rocks That Contain Gold. Several host rocks contain gold and you should familiarize yourself with these rocks.

Although there are about twenty different gold minerals, all of them are quite rare. Therefore, most gold found in nature is in the form of the native metal. Gold occurs in hydrothermal veins deposited by ascending solutions, as disseminated particles through some sulfide deposits, and in placer deposits.

Gold Processing. The first step entails processing of the gold ore. The gold ore once mined is processed by separating the gold mineral from the crude matter holding it together. The ore is then pulverized using pressure to create very fine particles. The fine particles are then heated in a furnace to temperatures over 1,064 degrees Celsius ...

Since gold is much denser than the host rock (19.3 g/cm³ vs 2.5-3.0 g/cm³), the heavy gold particles sink into the table's ridges while the lighter waste washes off. Other gravity methods like spirals and centrifugal concentrators also exploit this density difference between gold (19.3 g/cm³) and the rock (2.5-3.0 g/cm³) to separate the ...
