Dear readers,

Achieving the optimum with as little effort and expense as possible – this is the central objective in many areas. Even in processing technology, efficiency plays an essential role, as the various reports in our Focus Industry section will illustrate.

Especially ore processing is particularly energy-intensive, as Dr. Harder explains using copper and gold mining as an example. The second expert contribution addresses – still against the background of efficiency enhancement – the advantages of dry processing of coal by means of air jigging machines from allmineral, in particular in areas with a lack of water.

Even though we are still in the middle of autumn, the report about the anniversary edition of the Mining Calendar 2018 is due to the imminent end of theyear. In the course of the past 25 years, the calendar has developed into a popular gift and a sought-after collector’s item at the same time.

Let yourself be inspired!
