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).

Different milling conditions, such as wet or dry, and use of different grinding media have a great impact on the flotation performance of sulphide minerals. In the present study, the effects of wet and dry grinding and the use of different grinding media, such as mild steel (MS) and stainless steel (SS), were investigated on a Cusulphide ore. The samples were ground as dry and wet with both ...

Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has remained dominant for over 130 years because of its selectivity and feasibility in the mining industry. For this reason, the industry has been adjusting its methods for the extraction of gold, by ...

Gold milling, which is also known as fine grinding, pulverising or comminution, is a grinding process that reduces materials into a powder or finer sized particles. Milling is used to recover the maximum amount of gold from the ore by finely grinding it so that gold particles can be removed through gravity separation and/or chemical extraction.
