Energy. Rock drilling, blasting, and comminution (crushing and grinding) consume a vast amount of energy in hard rock mines. As mentioned in Sect. 1, statistics from hard rock mines indicates that drilling and blasting consumes 2% and comminution does 53% of the total energy input in the whole production chain from mining to mineral processing (Spathis 2015), see Fig. 1.

The Mining Model corresponds to the modeling of the mineral extraction using geostatistical simulations, and the further SAG mill feed management to achieve the demandside management (DSM). This way, the energy consumption of the mill can be controlled as a way to look if a deeper integration of the solar energy can be achieved.

Mineral processing Concentration, Separation, Flotation: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In largescale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic ...

Grinding Mills. Barry A. Wills, James A. Finch FRSC, FCIM,, in Wills' Mineral Processing Technology (Eighth Edition), 2016 Circuit Operation. Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number of grinding circuits in parallel, each circuit taking a definite fraction of the feed.

Crushing, a form of comminution, one of the unit operations of mineral processing. In the field of extractive metallurgy, mineral processing is the process of separating commercially valuable minerals from their ores. [1] Depending on the processes used in each instance, it is often also known as ore dressing or ore milling .

Reliable prediction of grinding media consumption can therefore play an important role in the management and control of these costs, and the overall cost of mining operations. The cost associated with grinding media is chiefly determined by two factors, viz. the price and wear performance of the grinding media.

Comminution, consuming close to 40% of total energy contains a single piece of equipment—the grinding mill—that is typically the largest single consumer in a mining operation. Noting that the comminution area also includes crushing, pumps and other equipment—the grinding mill(s) are normally the largest single energy consumer.
