The efficiency of copper ore comminution: A thermodynamic

Aug 01, 2017This study analyzes the exergy efficiency of comminution using a laboratory sized dry ball mill and a copper mineral ore from central Chile. In this research, we develop a minimum work index from uniaxial compression tests results on the ore fitted to Morrell’s comminution energy equation using Hukki’s constant mineral parameter.

Copper Ore an overview ScienceDirect Topics

Aniko Toth, Elemer Bobok, in Flow and Heat Transfer in Geothermal Systems, 2017. Abstract. In the 1970s an important copper ore mine was implemented in Recsk, Northern Hungary. Unfortunately, as soon as the roadways were finished the activities were suspended, because of the decreasing price of copper in the international market.

Copper Mining and Processing: Processing of Copper Ores

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively,
