COMMINUTION Comminution, the first step in the extraction of a metal, involves the breakage and pul verization of the ore until reduced to particles which are fine enough for the mineral of interest to become available for further processing. Comminution is necessary where the metal of interest occurs in a lode or a vein deposit, also defined as a massive ore, because in such an …

Although comminution facilities are typically established taking into consideration the nature of the ore (Connelly 2013), however, a primary challenge is to continuously optimize energy consumption coupled with reduction in CO2 footprint during minerals processing operations. In the processing of ROM ore, the effectiveness of operations strongly depends on the energy …

Comminution is important in mineral processing, where rocks are broken into small particles to help liberate the ore from gangue. [3] Comminution or grinding is also important in ceramics, electronics, and battery research. [4] Mechanical pulping is a traditional way for paper making from wood. The mastication of food involves comminution.

With regard to water consumption in mineral processing a dry comminution process allows greater control of water use. The addition of process water would be steered solely by processing downstream of the comminution circuit, flotation or leaching for example, and not by milling and classification requirements.

Comminution Because most minerals are finely disseminated and intimately associated with the gangue, they must be initially “unlocked” or “liberated” before separation can be undertaken. This is achieved by comminution in which the particle size of the ore is progressively reduced until the clean particles of mineral can be separated by such methods as are available. Comminution in …
