Reduction of Fragment Size from Mining to Mineral Processing

2.1 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 Grinding (and/or milling, which is a form of grinding) is accomplished by abrasion and impact of the ore by the free motion of unconnected media such as rods, balls, or pebbles.

Applying statistical analysis to the above data allows the ore to be classified into a specific class. This approach to the design of mineral processing engineering allows for the preliminary development of concept concerning crushing, grinding, classification and flotation process units, together with a forecast of the metal Crushing and grinding is the most costly step in mineral processing because the power needed to liberate the minerals is very high. In this sense, grinding is commonly said to be the key to good mineral treatment and the major consumer of energy, accounting for up to 50% of a concentrator’s energy consumption ( Table 6.3 ).Mineral Processing SpringerLink
