Concentrates & Ore
An Ore is a naturally occurring material in shape of rock which contains a metal compound. When extracted from the mine ore is typically crushed, ground and run through a beneficiation process to produce enriched ore called Concentrate . One of the most widely used ore beneficiation process is called froth flotation where the minerals are separated from each other. The chemical modification enables the mineral particles to attach to an air bubble in the flotation cell and rise through the pulp towards the surface of the froth. The mineral is then physically separated from the remaining pulp material and removed for further processing. The economics of extracting and further processing of a particular ore are changing with the time as some metals are becoming very rare and despite the cost of their extraction they are currently being mined when it was previously considered too expensive.
