Concentration of Ores | eMedicalPrep

When an ore has a low percentage of the desired metal, a method of physical concentration must be used before the extraction process begins. In one such method, the ore is crushed and placed in a machine where, by shaking, the heavier particles containing the metal are separated from the lighter rock particles by gravity.

Concentration of Ore - YouTube

All ore deposits are mineral deposits, but the reverse is not true. Ore deposit is an economic term, while mineral deposit is a geologic term. Whether a given mineral deposit is also an ore deposit depends on many factors other than the level of concentration and the size of the deposit; all factors that affect the mining, processing, and transporting of the ore must be considered as well.

Mineral processing - Wikipedia

In this process, the particle size is of particular importance. Unwanted accessory minerals cannot be separated from the ore if the particles are too big and the ore concentrate gathered has a low purity. Overgrinding however leads to low throughput and high milling costs in addition to an increased requirement for chemicals in flotation.
