The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and directsmelting ores are produced, the bulk of the copper ore mined is concentrated.

Energy costs typically comprise one of the largest ongoing costs of mining operations, of which 70% is devoted to the comminution of the ore (Norgate and Jahanshahi, 2010). Furthermore, the most significant energy cost occurs in the grinding circuit of the Milling section, where up to 97% of the energy cost is incurred (Ballantyne et al., 2012).

Milling also refers to the process of breaking down, separating, sizing, or classifying aggregate material ( mining ore). For instance rock crushing or grinding to produce uniform aggregate size for construction purposes, or separation of rock, soil or aggregate material for the purposes of structural fill or land reclamation activities.

Copper ore with a particle size between 01 mm was used in the experiments. A model was created that determines the relationship between the processing time and efficiency of the grinding, and can be used for the optimization of the process. A comparison of the relative growth of particle size fractions in milling products was performed.

Crushing and milling account for just over 50% of copper mine site energy consumption 3 making them a primary target for cost reduction. The goal is to grind the ore just enough for optimum copper mineral liberation in the froth flotation plant circuit. Undergrinding reduces recovery; overgrinding reduces throughput and wastes energy.

The mines around Mosbach and Volperhausen were part of the Ründeroth district and worked on siderite veins of the Siegerland type. In the beginning of the mining period copper ore was mined, later on up to 1925 the siderite. Most important mines were "Magdalena" and "Georg Sonne". Magdalena mine started in 1890 and closed in 1912.
