Mine-to-process integration and optimization

Comminution. Using measured ore characteristics, comprehensive plant surveys, historical operating data, plus our extensive database of over 450 operations globally, we develop site-specific models for any comminution circuit, ranging from primary crushing through to fine and ultrafine grinding. Comminution uses at least 3% of total global electricity production and, according to the Coalition for Energy Efficient Comminution, it accounts, on average, for more than 50% of a mine's energy consumption and 10% of total production costs. Energy-efficiency is one of the pillars of comminution circuit design and ignoring this can be the

method of coal briquetting (Figure 1), and being used in comminution applications since the mid 1980s. However, while HPGR is now commonplace in the briquetting, cement, diamond, and iron ore sectors, its adoption for true hard rock comminution duties has been slow and cautious, and there are still only a very few hard rock operations to have If there will be changes in ore type, one should assess how comminution circuits handle ore variation. In the case of a SAG and ball mill circuit either machine could be the bottleneck. Corrective actions depend on both circuit and how much ore variation is experienced.
