Ore processing is a chain of processing applications which treats run of mine to firstly high-grade concentrate (concentration of ores) and then to the pure mineral or metal. The refined ore is used in manufacturing equipment and machinery in numerous industries, or is for sale in industry, commerce and consumer industries.
To achieve this, ore processing separates the different mineral characteristics using various ore dressing (ore processing) methods. The primary processes are crushing and grinding of ore, ore sizing and separation. To separate the ore into applicable sizes for further processing, screening, classifying, concentration separation, heavy medium separation, gravity and/or magnetic separation, and flotation applications are used.
Subsequent to these processes, separating the from the concentrate produced or from gangue (waste material) is necessary. This is known as dewatering and allows for the water used in ore separation processes to be recycled and reused. It is subsequently sent to beneficiation plants for further processing.
