difference between washing and screening of iron ore

Beneficiation process and separation method,crushing ...

 · Ore washing: In order to avoid clogging of the crushing and screening equipment by the mud in the mud-containing mineral raw materials, ore washing is required. If the raw materials contain soluble useful or harmful ingredients, they must also be washed. Ore washing can be carried out in a scrubbing machine or in a screening and grading equipment.

What is a Copper Cathode? (with pictures)

One of the most common types of copper ore is a mixture of copper, iron and sulfur. This ore is called chalcopyrite. After the ore is mined, it is heated in a furnace to 2,012° F (1,100° C). At this temperature, oxygen reacts with the iron in the ore, turning the ore into three substances, iron oxide, sulfur dioxide and copper sulfite.
