Copper ore crushing process 1. Beneficiation methods of copper sulfide ore Copper sulfide can be divided into single copper ore, copper sulfur ore, copper-molybdenum deposit, copper nickel, carrollite and so on. Basically, only flotation can be considered in its separation. Almost all copper sulphide ores contain iron-bearing sulfides, so in a ...

Gravity separation is the oldest known ore beneficiation technique and is practiced extensively in 'Nature'. Earliest recorded human use of gravity separation was recovery of gold by panning from the Upper Nile by ancient Egyptians, dating back to 1900 BCE. Gravity separation is a physical process which consists of the separation of ...

Process removing the gangue minerals of an ore resulting in a higher grade product. In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product ( ore concentrate) and a waste stream ( tailings ).
